A warning sign is provided in your warranty packet. Please install it at a location near your spa, where it is visible to the user of the spa. For additional or replacement signs please contact your local Jacuzzi Spas dealer and reference item number #6530-082. CAUTIONS . Persons suffering from heart disease, diabetes, high or low blood pressure, and any condition requiring medical treatment, pregnant women, the elderly, or infants should consult with a physician before using a spa. 2. The Consumer Products Safety Commission/USA has stated that the water temperature in a spa should not exceed 04°F (40°C). Immersion in water in excess of 04°F (40°C) can be hazardous to your health. Page 6 3. Observe a reasonable time limit when using the spa. Long exposures at higher temperatures can cause high body temperature. Symptoms may include dizziness, nausea, fainting, drowsiness, and reduced awareness. These effects could possibly result in drowning. 4. Do not use the spa under the influence of alcohol, narcotics, or other drugs. Use of the spa under these conditions may lead to serious consequences. 5. Always test the spa water temperature before entering the spa. Enter and exit the spa slowly. Wet surfaces can be very slippery. 6. Never bring any electrical appliances into or near the spa. Never operate any electrical appliances from inside the spa or when you are wet unless such appliances are built-in by the manufacturer. 7. Proper chemical maintenance of spa water is necessary to maintain safe water and prevent possible damage to spa components. 8. Use the straps and clip tie downs to secure the cover when not in use. This will help to discourage unsupervised children from entering the spa and keep the spa cover secure in high-wind conditions. There is no representation that the cover, clip tie-downs, or actual locks will prevent access to the spa. Page 7 3.0 Choosing A Location IMPORTANT: Because of the combined weight of the spa, water and users, it is extremely important that the base upon which the spa rests be smooth, flat, level and capable of uniformly supporting this weight, without shifting or settling, for the entire time the spa is in place. If the spa is placed on a surface which does not meet these requirements, damage to the skirt and/or the spa shell may result. Damage caused by improper support is not covered under warranty. It is the responsibility of the spa owner to assure the integrity of the support at all times. We recommend a poured, reinforced concrete slab with a minimum thickness of 4 inches (0cm). Wood decking is also acceptable provided it is constructed so that it meets the requirements outlined above. The spa must be installed in such a manner as to provide drainage away from the spa. Placing the spa in a depression without provisions for proper drainage could allow rain, overflow and other casual water to flood the equipment and create a wet condition in which it would sit. For spas which will be recessed into a floor or deck, install so as to permit access to the equipment, either from above or below, for servicing. Make certain that there are no obstructions which would prevent removal of the cabinet side panels and access to the jets components, especially on the side with the equipment bay doors. 3.1 Outdoor Location In selecting the ideal outdoor location for your spa, we suggest that you take into consideration: . 2. 3. 4. 5. The proximity to changing area and shelter (especially in areas subject to colder climates). The pathway to and from your spa (this should be free of debris so that dirt and leaves are not easily tracked into the spa). The closeness to trees and shrubbery (remember that leaves and birds could create extra work in keeping the spa clean). A sheltered environment (less wind and weather exposure can result in lowered operation and maintenance costs). The overall enhancement of your environment. It is preferable not to place the spa under an unguttered roof overhang since run-off water will shorten the life expectancy of the spa cover. Page 8 3.2 Indoor Location For indoor installations, be certain to make provisions for proper ventilation. When the spa is in use, considerable amounts of moisture will escape. This can damage certain surfaces over time. If you have any questions regarding the placement or installation of your spa, consult your authorized Jacuzzi dealer. WARNING: In addition to maintenance of filters and water chemistry, proper ventilation is recommended to reduce the risk of exposure to viruses and bacteria that could be present in the air or water. Consult a licensed architect or building contractor to determine your specific needs if installing your spa indoors. 4.0 General Electrical Safety Instructions Your new Jacuzzi spa is equipped with a "state-of-the-art" equipment system. It contains the most advanced safety and self-protective equipment in the industry. Nonetheless, this spa must be installed properly to insure dependable usage. Please contact your dealer or local building department should you have any questions regarding your installation. Proper grounding is extremely important. Jacuzzi spas are equipped with a current collector system. A pressure wire connector is provided on the surface of the control box, located outside the equipment door (Figure-B, page 3) to permit connection of a bonding wire between this point and any ground metal equipment, metal water pipe or conduit within 5 feet (.5m) of the spa, or copper clad grounding rod buried within 5 feet (.5m) of the spa. Bonding wire must be at least No. 8 AWG (8.4mm2) solid copper wire. This is a most important safety assurance feature. Before installing this spa, check with the local building department to insure installation conforms to local building codes.

(Although the spa shell has been polished at the factory, you may want to treat it with a specially formulated spa cleaner. Consult your dealer for additional information prior to filling spa. Remove filter lid then remove filter cartridge from filter bucket. Fill Spa Place the end of your garden hose into the empty filter bucket. · 2. · CAUTION: Never fill with water from a water softener. If your water is extremely "hard", it is preferable to fill half-way with hard water and the rest of the way with softened water. Or, you may fill entirely with hard water if you use a special water additive available from your authorized Jacuzzi dealer. · Fill spa until water covers all jets but does not touch the bottom of the lowest headrest. DO NOT OVERFILL. IMPORTANT: Always fill your spa through the filter bucket after draining. Failure to do so may cause air to be trapped in either pump, preventing the pump from circulating water. Remove the hose and replace the filter cartridge. Page 4 3. Turn On Power Turn on power to spa at the home's circuit breaker. The heater and filter/circulation pump will automatically activate. If the control panel LCD flashes water temperature and "COOL" or "ICE", refer to section 5.0 (page 4-42) for additional information. Activate Jets Pump 1 Depress the JETS button on the control panel once to activate jets pump #. Add Start-Up Chemicals Add the spa water chemicals as recommended by your authorized Jacuzzi dealer.

To ensure healthy water conditions, always maintain a constant sanitizer reading within the levels recommended by the Association of Pool And Spa Professionals/USA printed on the inside cover of this manual. If sanitizer levels cannot be stabilized, perform the decontamination procedure steps 9-5 on page 6-8. Note: the "decontamination procedure" steps 9-15 should also be used after the spa has been "Winterized" (page 38) or has been sitting without power for an extended period. Set Spa To Heat To warm spa water to a comfortable temperature, follow these steps: The LCD display on the control panel displays the actual temperature of the spa water. Press either the COOLER (Down) or WARMER (Up) button once to display the "set" temperature for 5 seconds. If you want the water to heat to a different temperature, simply press COOLER (Down) or WARMER (Up) within 5 seconds. The set temperature increases or decreases by one degree each time one of these buttons is pressed. The heater will turn off when the temperature corresponding to the thermostat setting is achieved. 4. 5. 6. 7. · · Important Heater Details: · The maximum temperature for which the spa can be set is 04°F (40°C) and the minimum is 80°F (27°C). Page 5 · · Setting the thermostat at maximum will not accelerate the heating process. This will only result in a higher ultimate temperature. The heater operates until the water reaches the programmed "set temperature", then turns off. The heater will reactivate after the water cools to approximately .5° below the "set temperature." Place Cover On Spa Keeping the insulating cover in place anytime the spa is not in use will reduce the time required for heating, thereby minimizing operating costs. The time required for initial heat-up will vary depending on the starting water temperature. DANGER: Risk of injury, always check water temperature carefully before entering spa! 8. · · Decontamination Procedure (Steps 9-15) Steps 9-5 below are only required when sanitizer levels are unstable after performing steps -6 above. Disregard steps 9-5 below if sanitizer levels remain stable at 3 ppm to 5 ppm after performing steps -6 above. 9. Add 2.5 ounces of sodium dichlor for every 00 gallons of water. Refer to the table below for approximate water fill volume by model. CAUTION: Never add chlorine tablets (trichlor) to your spa for any reason! This chemical may damage components within your spa and void the manufacturer warranty. Water Fill Volume by Model Spa Model Approximate Fill Volume J355 ......................................363 US Gallons (,374 Liters) J365 ......................................374 US Gallons (,46 Liters) J375 ......................................480 US Gallons (,87 Liters) J385 ......................................550 US Gallons (2,082 Liters) Page 6 10. Leave spa cover open during this step to allow excessive chemical vapors to exit spa, protecting pillows and plastic knobs from chemical attack. If spa is indoors, open doors and windows for proper ventilation. Turn on all spa jets pumps for one hour, open all air controls, and place all massage selector knob(s) in their center "combo" position as shown (right). Note: You will need to press the jets pump button(s) every 20 minutes since these functions have an automatic 20 minute time-out function that turns them off. CAUTION: never leave your spa unattended for any reason while the cover is open and accessible to small children and animals! 11. Turn off power to the spa at the circuit breaker, then drain tub as outlined in section 13.2 "Draining And Refilling" page 35-36. 12. Fill spa until water covers all jets but does not touch the bottom of the lowest headrest. DO NOT OVERFILL. CAUTION: Never fill with water from a water softener. If your water is extremely "hard", it is preferable to fill half-way with hard water and the rest of the way with softened water. Or, you may fill entirely with hard water if you use a special water additive available from your authorized Jacuzzi dealer. 13. Consult your authorized Jacuzzi dealer for chemical recommendations, then add chemicals to spa water to achieve a constant sanitizer reading within the levels recommended by the Association of Pool And Spa Professionals/USA printed on the inside cover of this manual. 14. Turn on all jet(s) pumps when adding chemicals to ensure proper mixing and leave your spa cover open until the sanitizer level falls below 5 ppm to protect pillows and plastic knobs from chemical attack. CAUTION: Never leave your spa unattended for any reason while the cover is open and accessible to small children and animals. Page 7 CAUTION: To prevent the unlikely possibility of contracting a waterborne illness, maintain water chemistry within step 6 parameters. If you or other bathers experience such a condition, discontinue use and seek medical attention. 15. Establish a sanitizer reading between 3 ppm and 5 ppm, then allow the spa to set undisturbed for 8 hours. Retest water after 8 hours to determine if sanitizer levels are stable. If sanitizer levels are stable, your spa is ready for use. To ensure healthy water conditions, always maintain a constant sanitizer reading within the levels recommended by the Association of Pool And Spa Professionals/USA printed on the inside cover of this manual. If sanitizer levels are not stable at this time, it will be necessary to repeat this procedure in its entirety (steps -5) until stable sanitizer readings are achieved.

Page 23 10.0 Operating Instructions Your Jacuzzi® spa has a touch-sensitive control panel, diverter valves, and air control knobs located on the top rim of the spa (section 9.0-9.2 page 2-23). These controls let you operate many of the special functions of your Jacuzzi spa. By familiarizing yourself with the following information, you will be able to gain the full benefit afforded by the various functions of your spa. 10.1 Set Spa To Heat To warm spa water, follow these steps: . The LCD display on the control panel displays the actual temperature of the spa water. Press either the WARMER ( + ) or COOLER ( - ) button once to display the "set temperature" for 5 seconds. If you want the water to heat to a different temperature, simply press WARMER ( + ) or COOLER ( - ) within 5 seconds. The set temperature advances or decreases by one degree each time one of these buttons is pressed. 2. The heater will turn off when the temperature corresponding to the thermostat setting is achieved. Important Heater Details: · The maximum temperature for which the spa can be set is 04°F (40°C) and the minimum is 80°F (27°C). · If spa is powered by the minimum required amp service (section 5.0, page 0-), turn off all high speed pumps to operate heater. Note: jets Pump 2 and J-385 Pump 3 run only in high speed. · Setting the thermostat at maximum will not accelerate the heating process. This will only result in a higher ultimate temperature. · The heater operates until the water reaches the programmed "set temperature", then turns off. The heater will reactivate after the water cools to approximately .5° below the "set temperature." 10.2 View Pressing this button inverts the main four-digit display on the command center's LCD screen to allow easy reading from either inside or outside the spa. 10.3 Light The spa light offers 6 constant color variations and a unique random mode for enhanced spa enjoyment. Press the LIGHT button once to turn the spa light on in "Random" mode, then Page 24 repeatedly press the button to turn the light off or to select one of 6 constant colors illustrated below. RANDOM OFF RED OFF GREEN OFF BLUE OFF ORANGE Spa Light Sequence OFF TEAL OFF VIOLET OFF You must press the LIGHT button within 5 seconds between each "off" or "color" step in the light sequence to prevent it from resetting. Pressing the button after 5 seconds restarts the sequence at "Random" mode. This mode automatically changes the light color every 8 to 20 seconds. Note: Any time the spa light is manually turned on, it will automatically turn off after approximately 1 hour. If you desire more light at this time, simply turn the light back on. 10.4 Activate Pump 1 The JETS 1 Button controls the 2-speed pump #. Pressing this button cycles pump # from off, to low speed, to high speed, and back to off. 10.5 Activate Pump 2/Pump 3 On two pump J-355, J-365, J-375 models, the button labeled JETS 2 controls the high-speed jets pump #2. Pressing this button cycles jets pump #2 on and off. On the three pump J-385 models, this button controls both jets pump #2 and jets pump #3 in the following sequence: A. B. C. D. Press Press Press Press once to turn on jets pump #2 in high-speed; a second time to turn on jets pump #3 in high-speed; a third time to turn off pump #2; a fourth time to turn off pump #3. Auto Turn Off -- Anytime a jets pump has been manually turned on, it will automatically turn off after approximately 20 minutes. If at this time you desire more jet operation you may simply turn the jets pump(s) back on. Page 25 10.6 Selecting Desired Massage Action Your Jacuzzi® spa is equipped to allow you to customize B C the massage action you desire. Each model incorporates a massage selector that allow you to customize the masA sage and performance by diverting water between various jet systems. Simply turn massage selector to position A (Combo), B, or C to divert water pressure to various jet groups. Note: The massage selector valve(s) is intended to operate in positions A (Combo), B, and C for optimum performance. It is considered normal for sound levels within the valve to vary between positions due to the large amounts of water flowing through it! For optimum filtration benefits, leave the valve in position A when spa is covered. Select position B or C for maximum jet performance during spa use. 10.7 Adjusting Individual Jet Flow The water flow to the individual jets in your spa can be increased or decreased by rotating the outside jet face. Note: Always keep at least 6 adjustable jets open at all times. 10.8 Adjusting PowerPro Jets With the nozzles of the PowerProTM Jets positioned straight ahead, the jet stream will be stationary. Pushing the nozzle to one side causes the jet nozzle to rotate, moving the jet stream in a circular pattern. The jets may not spin with jets pump 1 on low speed. 10.9 Waterfall Feature The waterfall feature allows you to independently control it for a customized soothing effect. The JETS button activates the waterfall feature. Then, each fall is individually adjusted moving the control lever next to it forward or backwards. To turn on, move lever inward. To turn off, move lever outward. 10.10 Air Controls Certain jet systems have their own "push-button" air control (page 22-23). Each control introduces air into the water lines that supply that specific jet group. Simply press any air control button (once) to open; then press a second time to close. To minimize heat loss, all air controls should be closed when the spa is not in use. Page 26 10.11 Optional Jacuzzi Audio System Spas equipped with the optional Jacuzzi Stereo System offer enhanced spa enjoyment. These models include an integrated AM/FM/CD receiver with two high-quality marine speakers for unsurpassed sound quality and long-life. Both speakers located on spa corners (section 9.0, page 2) are designed for manual extension and retraction. To expose each speaker for audio, simply press it's release button to unlatch the "pop-up" mechanism. To retract each speaker before covering spa, gently press downward on each speaker enclosure until you feel a slight "click", then release. See section 22.0 page 50, for addtional information. CAUTION: Never step or sit on a speaker enclosure! This type of misuse will damage the speaker enclosure latching and track mechanism. Always retract speakers prior to covering spa. 11.0 Automatic Filtration Cycles Your new spa includes a programmable 24-hour circulation pump which filters the water continuously. The circulation pump draws water through one of two filter cartridges to effectively remove small debris in your spa. Note: the 24-hour circulation pump system also supplies heated water to the spa when the heater turns on. See section 12.4 page 31 for programming details. The control system activates a programmable "standard" or "economy" skimming/heating cycles to remove larger debris missed by the 24-hour circulation pump filtration system. These cycles utilize jets pump# and the skimmer bag and second filter cartridge to quickly clear "skim" the water of large debris and minimize their "bath-tub ring" effect. Apart from their skimming benefit, each mode also effects the operation of your spa's heater. Refer to sections .-.2 below for additional information. 11.1 Standard Skimming/Heating Mode Standard skimming/heating mode is typically selected by customers in cold climates where heat up times are extended due to lower ambient temperatures. In this mode, the water temperature is regulated by the set temperature, 24-hour circulation pump, and heater which turns on as needed. After the programmed set temperature is reached, the Page 27 heater turns off and the circulation pump continues to operate 24-hours to filter and clean your spa (unless programmed otherwise). 11.2 Economy Skimming/Heating Mode Economy skimming/heating mode is typically selected by customers in warm climates where heat up times are minimized due to higher ambient temperatures. In this mode, the water temperature is regulated by the set temperature, 24-hour circulation pump, and heater only while a programmed skimming/heating cycle is running (unless in summer logic; see note below). Note: this mode consumes less energy than the standard mode outlined above. 11.3 Selecting Standard or Economy Skimming/Heating Mode Press the MODE button to select either "Standard" or "Economy" skimming/heating mode. The control panel's indicator on the right side of the LCD changes to indicate which mode is selected. When an automatic skimming/heating cycle activates, the LCD screen displays the following message: FILTER CYCLE ON Summer Logic: In warm weather, the water temperature in the spa may exceed the set temperature. This condition may occur due to heat transference from the main pump and 24-hour circulation pump. If the water temperature is higher than 95°F (35°C) and rises two degrees above the set temperature, a "Summer Logic" condition occurs that deactivates the circulation pump and ozonator (if equipped). This safety feature cannot be altered! The circulation pump and ozonator will remain off until the water temperature cools to the set temperature (except between 12AM-2AM when the circulation pump runs for it's mandatory 2-hour "clean-up" cycle). To help prevent a "Summer Logic" condition, it may be necessary to reduce skimming/heating cycle and/or circulation pump run times in warm weather. 11.4 Preset Skimming/Heating Cycles Your spa comes with four 30-minute skimming/heating cycles already programmed in, beginning at 6:00 a.m., noon, 6:00 p.m., and midnight. You can easily change the start time, or the cycle length for any of these cycles to suit your individual needs by following the steps in section 2.2, page 29-30. Page 28 11.5 Clean-Up Cycle The clean-up cycle is once per day in both Standard and Economy mode at 2:00 PM for two minutes. This is not user programmable. Jets pump #2 (and J-385 jets pump #3) activate for one minute to circulate any water in the plumbing. After minute they go off, then jets pump # turns on and runs for minute. If the skimming/heating cycle is also set at 2:00 PM, jets pump # will continue to run for the duration of the cycle. 12.0 Programming Instructions 12.1 Adjusting Time of Day The control system remembers the time of day even in the event of a prolonged power outage. However, it may occasionally be necessary to reset the time of day. For example: if you are not in the Pacific Time Zone you will want to reset the time for your own time zone. (The system will automatically adjust to and from daylight savings time.) To accomplish this, press DISPLAY, MODE and DISPLAY within five seconds each. A number representing the hour will be displayed, followed by AM or PM. The hour will advance or decrease each time WARMER ( + ) or COOLER ( - ) is pressed within five seconds. Then, press DISPLAY again to display the minutes. Adjust the minutes as necessary by pressing WARMER ( + ) or COOLER ( - ) After 5 seconds, the display will return to normal. 12.2 Changing Skimming/Heating Cycles The control system allows you to easily adjust two separate aspects of each of the skimming/heating cycle: ) the time of day at which each cycle begins; and 2) the duration of each cycle. To make adjustments, first press CYCLE to enter the skimming/heating cycle programming mode. The LCD screen will display the following in the upper right corner: ADJUST FILTER CYCLE START TIME This means the system is ready to accept your changes to the start time for skimming/heating cycle number one. Simultaneously, the large four-digit display in the center of the screen displays the currently proPage 29 grammed start time for that cycle. At this point, you have four options. You may: . Press WARMER ( + ) or COOLER ( - ) to adjust the start time in increments of 30 minutes. 2. Press CYCLE to display and adjust each subsequent skimming/ heating cycle start time. With each press, the currently programmed status will be shown in the large four digit display. To adjust any display value, simply press WARMER ( + ) or COOLER ( - ). 3.

If no button is pressed within 30 seconds, the screen automatically returns to the standard water temperature display. At any time, you may check the programming of any aspect of any skimming/heating cycle by first pressing CYCLE then moving through the menu by pressing either CYCLE or SELECT. The programming is changed only by pressing WARMER ( + ) or COOLER ( - ) during this process. 12.3 Programming The Change Filter Reminder Your new spa is equipped with a programmable "Change Filter" reminder that appears on the control panel display after a CHANGE specified number of days. It is designed to remind you to FILTER clean and/or replace your filter cartridge(s) on a regular basis but does not affect spa operation in any way. This reminder must be reset at each filter cleaning interval. It offers a selectable range from 0-20 days or can be disabled. We recommend an initial setting of 30 days, after which you can easily determine whether you need to shorten or lengthen its interval by visually inspecting your filter cartridge. Refer to section 3. (page 33-35) for filter cleaning recommendations. Page 30 Programming Instructions . Press the CYCLE button six times. The main display reads "FIL" indicating the "Change Filter" display program has been accessed. 2. Press SELECT button once to display currently programmed duration or days elapsed since last filter cleaning interval. 3. Press UP or DOWN button to change duration as follows: 0 - 0 - 20 - 30 - 40 - 50 - 60 - 70 - 80 - 90 - 00 - 0 - 20 - OFF 4. Press DISPLAY button once to save changes and return to the standard water temperature display. Note: If no button is pressed within 30 seconds, the screen will automatically return to the standard water temperature display. 12.4 Programming Circulation Pump Run Time The control system allows you to easily adjust two separate aspects of circulation pump operation: . The time of day (start time) the circulation pump begins operating. 2. The length of time (duration) the circulation pump operates. The factory default start time is 2:00AM (Midnight). The default duration is 24 hours. To make adjustments, press the button labeled CYCLE five times to enter the circulation pump programming mode. The LCD screen will display ADJUST Circ. At this time the system is ready to accept your changes. · · · · · Press the SELECT button once. The previously programmed start time appears on the LCD display.

Press DISPLAY to make the circulation pump programming characters disappear from the screen and the main display return to showing the water temperature. If no button is pressed within 30 seconds, the screen will automatically return to the normal water temperature display Note: In standard skimming/heating mode only, the circulation pump automatically activates if the spa requires heat regardless of the programmed start time and duration. Page 3 12.5 Locking Skimming/Heating Cycles You may keep the skimming/heating cycle programs from being inadvertently altered by electronically "locking" them. To accomplish this, simply press CYCLE then, within 30 seconds, press DISPLAY, MODE and WARMER ( + ), within five seconds each. LOCKED A padlock symbol will appear on the screen. In this state, the status of the cycle programming may be checked, but may not be altered. To unlock the skimming/heating cycle programming to make changes, simply press DISPLAY, MODE and COOLER ( - ) within five seconds each. 12.6 Panel Lock To help prevent unauthorized use of your spa, the controls incorporate a unique panel locking system which disables the controls on the panel. To Lock The Panel: Press the DISPLAY, MODE, and WARMER ( + ) buttons, in order, within five seconds. A padlock symbol will LOCKED appear on the LCD screen. With the panel locked, none of the components can be turned on and the only settings that can be adjusted are the standard/economy operating mode and changing the time of day. All automatic spa functions will operate normally. To Unlock The Panel: Press DISPLAY, MODE, and COOLER ( - ), in order, within five seconds. The "lock" symbol will disappear. All buttons are now active. 12.7 Temperature Setting Lock To electronically lock the temperature setting, first enter the "temperature setting" mode by pressing WARMER ( + ) or COOLER ( - ). Then, within five seconds, press the three buttons described under "Panel Lock" in section 2.6. This will prevent the temperature setting from being changed by unauthorized persons but all other buttons will remain active. To unlock the temperature setting so that it can be adjusted, simply follow the instructions in section 2.6 above. Page 32 13.0 Spa Maintenance Proper and regular maintenance of your spa will help it retain its beauty and performance. Your authorized Jacuzzi Premium dealer can supply you with all the information, supplies, and accessory products you will need to accomplish this. 13.1 Cleaning The Filters Your Jacuzzi spa is equipped with a skimmer bag and two high performance filter cartridges located inside the filter skimmer. Fine debris are filtered by the circulation pump drawing water through the skimmer bag and circulation pump cartridge. Larger debris are filtered by the jets pump # drawing water through the skimmer bag and main pump cartridge during normal operation and at each skimming/heating cycle. The skimmer bag and filter cartridges provide unsurpassed water quality by tapping surface and suspended particles. An optional chemical feeder is available through your dealer. When the chemical feeder is in use, remove the chemical feeder during the filter cleaning stage. When turning the cap on the top of this filter, the cap will engage to allow the removal or installation of the filter. Remove the cap and chemical feeder by rotating the handle to the center of the on and off positions. Then lift the cap from the filter. Reinstall the chemical feeder on the filter prior to the filter installation in the spa. To avoid touching the chemical feeder, it is recommended that latex gloves be used during this process. All models include filters on their footwell suction covers that prevent debris from entering pump 2, when operating. These filters must remain in place to protect pump #2 plumbing network. They should be cleaned every 2 months, or when weak pump 2 performance is observed. To ensure optimum performance, clean and reuse both cartridges once a month. ALWAYS TURN POWER TO SPA OFF BEFORE CLEANING THE FILTER CARTRIDGES! Refer to steps A-J on the following page for "Cleaning/Replacement" instructions Page 33 C ar tri dg e 1 Trapped Air Bubbles If used, remove the chemical feeder as instructed prior to rinsing the filter cartridges. Rinse debris from filter pleats on each cartridge using a garden hose and high-pressure nozzle. Start at the top and work downward to the handle. Repeat until all pleats are clean. Submerge both filter cartridges in spa. Tilt threaded end upward to remove trapped air bubbles from each cartridge, then keep both cartridges submerged for step H. HH II JJ Page 34 C ar tri d ge 2 feeder as instructed prior to rinsing the filter cartridges. Rinse debris from filter pleats on each cartridge using a garden hose and high-pressure nozzle. Start at the top and work downward to the handle. Repeat until all pleats are clean. Submerge both filter cartridges in spa. Tilt threaded end upward to remove trapped air bubbles from each cartridge, then keep both cartridges submerged for step H. HH II JJ *Note: when replacing the filter cartridges, the chemical feeder must remain on the circulation pump inlet. The circulation pump inlet will have a grid across the wall fitting. Periodically, both filter cartridges will need a more thorough cleaning to remove imbedded oils and minerals. For this, we suggest cleaning as illustrated in step "F", followed by soaking the filter overnight in a plastic container filled with a solution of water and specially formulated filter cleanser available from your authorized Jacuzzi dealer. The chemical feeder should be removed during this process. The average life expectancy of each filter is approximately two years with proper care and water quality maintenance. Replacement cartridges may be purchased from your authorized Jacuzzi dealer. 13.2 Draining and Refilling About every 3 months you will need to replace the spa's water. The frequency depends on a number of variables including the amount of use, number of users, and attention paid to water quality maintenance. You will know it is time for a change when you cannot control sudsing and/ or you can no longer get the normal feel or sparkle to the water even though the key water balance measurements are all within the proper parameters. C ar tr i Page 35 CAUTION! READ THIS BEFORE DRAINING: To prevent damage to the spa's components, turn off power to the spa at the circuit breaker before draining it. Do not turn the power back on until your spa has been refilled. CAUTION: There are certain precautions to keep in mind when draining your spa. If it is extremely cold, and the spa is outdoors, freezing could occur in the lines or the equipment (see section 13.7 "WINTERIZING" page 38). On the other hand, if it is hot outdoors, do not leave the spa's surface exposed to direct sunlight. To drain your spa, perform the following steps: 1. Turn off power to spa at breaker. 2. Locate the drain valve on the front/lower plastic pan. Hold the larger (rear) body to prevent it from turning, then loosen and remove the front cap to expose the underlying male hose threads. 3. Attach a garden hose to the exposed threads. 4. Gently rotate the larger (rear) valve body /3 turn counterclockwise to unlock the drain valve. 5. Pull the larger (rear) body outward to open drain. 6. After the spa drains, perform steps 2-5 in reverse order to close the drain prior to refilling the spa. After refilling, turn on power to the spa and follow the steps listed under "Spa Fill Up Procedure." Always fill your spa through both filter basket wall fittings (section 7.0 page 4). 13.3 Cleaning The Spa Interior To preserve the sheen of your spa's surface, it is crucial that you avoid using abrasive cleaners or cleaners which have adverse chemical effect on the surface. If you are not certain as to the suitability of a particular cleanser, consult your authorized Jacuzzi dealer. Regardless of the cleanser used, use extreme care to assure that no soap residue is left on the surface. This could cause severe sudsing when the spa is refilled. Page 36 13.4 Pillow Care Remove and clean the headrest pillows as needed with soapy water using a cloth or soft-bristle brush. To maintain water resistance and luster, apply a quality vinyl conditioner once a month. Always remove the pillows when adding chemical shock treatment to the spa water. The pillows can be returned to the spa when the sanitizer reading drops below 5 ppm. CAUTION: Never attempt to remove the pillows by pulling on them! The pillows utilize a bolt-on design that prohibits removal without tools. To remove pillows: . Grasp center pillow insert (A) with finger tips and gently pry outward from pillow base (C). 2. Use a standard screwdriver to loosen and remove mounting bolts (B) from pillow base. 3. Assemble in reverse order after cleaning. DO NOT overtighten pillow mounting bolts! 13.5 Maintaining the Cover Using the Jacuzzi insulating spa cover anytime the spa is not in use will significantly reduce your operating costs, heat-up time and maintenance requirements. To prolong the life of the cover, handle it with care and clean it regularly using mild soap and water. Periodic treatments with a special conditioner developed for Jacuzzi spa covers will help protect against deterioration caused by UV rays from the sun. Never allow anyone to stand or sit on the cover, and avoid dragging it across rough surfaces. 13.6 Maintaining The Cabinet Your new spa's synthetic cabinet requires little or no maintenance of any kind. To clean, simply wipe cabinet with a clean towel and mild soap solution. CAUTION: Never spray cabinet with a garden hose for any reason since this action may induce an electrical short in the spa's electrical equipment. Page 37 13.7 Winterizing Your Jacuzzi® spa is designed to automatically protect itself against freezing when operating properly. During periods of severe freezing temperatures, you should check periodically to be certain that the electrical supply to the spa has not been interrupted. In extreme, bitter cold weather less than -20°F (-29°C), reset the filter cycles for 24-hour operation to protect the spa (i.e. four 6-hour cycles). If you do not intend to use your spa, or if there is a prolonged power outage during periods of severe freezing temperatures, it is important that all water be removed from the spa and equipment to protect against damage from freezing. For expert winterization of your spa, contact your authorized Jacuzzi dealer. In emergency situations, damage can be minimized by taking the following steps: . Follow the directions in section 3.2 page 35-36 for draining the spa. 2. As the water level drops below the seats, use whatever means necessary to get the water out of the recessed seating areas and into the footwell. 3. When the water level ceases to drop, use whatever means available to remove any remaining water from the footwell. 4. Turn off power to the spa. 5. Remove the equipment-side cabinet panels and locate the drain plugs in the front of the pump(s) (Figure-A, page 3). Remove these plugs to allow the water to drain out of the pumps and heater. Note: Approximately one to two gallons will be released during this procedure. Use a wet/dry vacuum or other means to keep this from flooding the equipment compartment. Replace the drain plugs. 6. Loosen the hose clamp on the circulation pump intake behind the control box (Figure-A, page 3) and pull the hose off (twist hose back and forth while pulling outward). Tip hose down and allow to drain, then reinstall hose and clamp. 7. Re-install cabinet side panels and cover spa so that no casual moisture can enter into it. Consult your authorized Jacuzzi dealer if you have any questions regarding winter use or winterizing. Page 38 13.8 Restarting Your Spa in Cold Weather If you want to start up your spa after it has sat empty for a time in freezing temperatures, be aware that the water remaining in certain sections of the piping may still be frozen. This situation will block water flow preventing the spa from operating properly and possibly damaging the equipment. We recommend you consult your authorized dealer for guidance before attempting to re-start your spa under these conditions. 14.0 Water Quality Maintenance Maintaining the quality of the water within specified limits will serve to enhance your enjoyment and prolong the life of the spa's equipment. It is a fairly simple task, but it requires regular attention because the water chemistry involved is a balance of several factors. There is no simple formula, and there is no avoiding it. A careless attitude in regard to water maintenance will result in poor and potentially unhealthful conditions for soaking and even damage to your spa. For specific guidance on maintaining water quality, consult your authorized Jacuzzi dealer who can recommend appropriate chemical products for sanitizing and maintaining your spa. CAUTION: Never store spa chemicals inside the spa's equipment bay. 14.1 pH Control pH is a measure of relative acidity or alkalinity of water and is measured on a scale of 0 to 4. The midpoint of 7 is said to be neutral, above which is alkaline and below which is acidic. In spa water, IT IS VERY IMPORTANT TO MAINTAIN a slightly alkaline condition of 7.2 to 7.8. Problems become proportionately severe the further outside of this range the water gets. A low pH will be corrosive to metals in the spa equipment. A high pH will cause minerals to deposit on the interior surface (scaling). In addition, the ability of the sanitation agents to keep the spa clean is severely affected as the pH moves beyond the ideal range. That is why almost all spa water test kits contain a measure for pH as well as sanitizer. 14.2 Sanitizing To destroy bacteria and organic compounds in the spa water, a sanitizer must be used regularly. Chlorine and bromine are the two most popular sanitizers used to date. Many other additives are availPage 39 able for your spa. Some are necessary to compensate for out-of-balance water, some aid in cosmetic water treatment and others simply alter the feel or smell of the water. Your authorized Jacuzzi dealer can advise you on the use of these additives. CAUTION: Do not use chlorine tablets (trichlor) in your spa. This chemical can have an extremely corrosive effect on certain materials in the spa. Damage caused by use of this chemical, or improper use of any chemicals, is not covered under the spa's warranty. 14.3 Optional CD Ozone Water Maintenance System If you have elected to have your spa equipped with the optional Jacuzzi CD ozone water purification system you will find that your water stays fresh and clear with significantly less chemical sanitizer usage. You will also probably be able to go longer between complete spa drainings. The CD ozone unit operates in conjunction with the 24-hour circulation pump. 14.4 Summer Logic When the actual spa water temperature reaches up to 2°F (°C) above the set temperature, the spa goes into "summer logic." The circulation pump will turn off automatically to avoid adding additional heat to the water, eventually creating an overheat condition. This setting is not userprogrammable. Note: The summer logic does not take effect until the spa water temperature reaches 95°F (35°C). This condition is more likely in excessively hot weather. Remember, the spa's ability to cool is directly affected by the ambient temperature. An excessively hot ambient temperature may prevent the spa from cooling down because it's fully insulated construction is designed to retain heat and to minimize operating costs. Page 40 15.0 Troubleshooting - Display Messages There are a number of unique functions designed into your Jacuzzi spa to protect it from damage and/or to aid in troubleshooting. Below is a listing of all the possible messages along with their meanings: MESSAGE MEANING Overheat Protection (Heater is deactivated, pump's low speed is activated). Water temperature is above acceptable limits. Do not enter the water! To correct condition: · Remove spa cover and allow your spa to cool down. · Set the spa in Economy Mode page 28. Do not keep the temperature setting too low as to keep the circulation pump in Summer Logic page 40. · If the condition persists contact your authorized deal er. If the spa water is more than 20°F (-7°C) cooler than the temperature set point, the 24-hour circulation pump and heater will automatically activate to provide freeze protection. The spa will stay in this mode until the water temperature reaches 5°F (-9°C) below the set temperature. No corrective action is necessary. * FLOW SWITCH (Heater is deactivated. Pump may also be deactivated). Proper flow of water is inhibited or a flow switch has malfunctioned. Check for proper water level and for a clogged circulation pump filter cartridge (Section 3., Page 33-35). Contact your authorized Jacuzzi dealer or service center. *NOTE: THIS MESSAGE CAN ALSO APPEAR IF THE PUMP HAS NOT REGAINED PRIME AFTER THE SPA HAS BEEN DRAINED AND REFILLED. IF YOU SUSPECT THAT THIS IS THE CASE, SEE THE INSTRUCTIONS ON PAGE 43 UNDER "PUMP DOES NOT OPERATE BUT LIGHT DOES." Panel buttons have been pressed too many times in a short period of time. Because this could cause excessive wear on equipment components, panel buttons are temporarily deactivated. Panel buttons will automatically re-activate if no button is pressed for 30 seconds. Page 4 Circuit board temperature has exceeded acceptable limit. This message will disappear when the circuit board temperature drops below acceptable limit. If condition persists, provide shade for equipment side of spa. FREEZE PROTECTION A potential freeze condition has been detected. No action is required. Pump(s) operate until the spa is out of danger. Note: This error commonly occurs when the spa is first filled because tap water is often very cold. Communication between the control panel and/or remote control panel and circuit board is faulty. Contact your authorized Jacuzzi dealer or service center. "WATCHDOG" (spa is deactivated) A problem has been detected which could cause damage to the spa or its components. Contact your authorized Jacuzzi dealer or service center. OPEN SENSOR (heater disabled) OR SHORTED SENSOR (spa is deactivated) The high-limit temperature sensor is non-functional. This must be repaired only by a dealer or authorized Jacuzzi service center. OPEN OR SHORTED SENSOR (heater disabled) The main sensor is non-functional. This must be repaired only by a dealer or authorized jacuzzi service center. CLOSED OR SHORTED FLOW SWITCH ON SYSTEM STARTUP (system disabled) Flow switch is non-functional. This must be repaired only by an authorized Jacuzzi dealer or qualified service organization.

Remove waterfall side filter cartridge and insert end of garden hose into its fitting. Seal-off pipe opening around hose using a large, clean rag and turn on maximum water flow through the hose. After about 30 seconds, turn off water, remove hose and rag, reinstall filter and activate pump # on high speed. Another method of priming the spa's pump(s) is as follows: 1. Turn off the power to the spa. 2. Remove the handle from diverter valve (Section 9.0, Page 2) 3. Loosen the diverter valve cap slightly (counterclockwise), listening for the air to seep out. 4. Tighten the cap finger-tight, replace the diverter valve handle, and turn the spa's power back on. Page 43 Note: This method must be used for the single speed jets pump(s) in all spas because Jets pump #2 (and J-385 jets pump #3) are not connected to the filter. CAUTION: If freezing conditions exist and pump is not operational, take measures to protect the system from freeze damage. See "Winterizing" (page 38). POOR JET ACTION . 2. 3. 4. 5. 6. Make certain the jets pump is on high speed. Check position of diverter valve Open air control for selected jet system. Check for adequate water level. Check for dirty filter cartridge. Check for dirty filters on both pump #2 footwell suction covers (page 2). WATER IS TOO HOT. . Reduce thermostat setting. 2. Reduce skimming/heating cycle length. Even with heater off, water temperature can increase from prolonged pump operation (section 2.2, page 29-30). . Check thermostat setting. 2. Keep the cover in place while heating. 3. Verify which skimming/heating mode is selected, standard or economy (section ..2, page 27-28). 4. If "heater on" indicator is lit, but no temperature rise is experienced after a reasonable period of time, contact your dealer or authorized service center.
