October 1993 Page 3 IS100 and IS150 FOR THE INSTALLER 1. Locate the Ice Station on the counter. Allow vertical clearance above unit for the removal of the cover, and for pouring ice into the hopper. 2. Plan the unit drain. Two tubes (5/8" and 3/4" I.D.) are located at the back of the cabinet. Routing is either thru the back or base. Sufficient fittings are indluded with the unit to install in most cases. 3. In order to comply with National Sanitation Foundation (NSF) requirements, this unit must be either elevated above the counter top sufficiently to provide space for cleaning under the unit or sealed to the counter top. Elevating the unit may be accomplished by using the optional legs. They will screw into threaded holes in the base of the unit. If the unit is to be sealed to the counter top, the drain and soda tubing should be available and planned such that the connections may be finished after the unit has been sealed to the counter. Sealing may be accomplished by the use of room temperature vulcanizing (RTV) rubber sealant such as General Electric IS 808 Industrial Sealant, Dow Corning 731 (Scotsman part number 19-0529-01) or the equivalent. With the unit located on the counter as desired: A. Tilt or lift the unit to expose the bottom flanges of the base frame. B. Apply the sealant to cover the bottom flanges of the base frame. C. Return the unit to the desired position on the counter top. D. Add sealant around the base frame and counter top to provide a seal with a radius of 1/2". Follow the sealant manufacturer's instructions on the package for working with the sealant, and cleaning up. E. Seal around all access holes in the counter top with Permagum or Mortite caulk or an equivalent material. October 1993 Page 4 USE LEGS OR SEAL TO COUNTERTOP CABINET DRAIN TUBES IS100 and IS150 INITIAL START UP 1. Sanitize the ice storage system as instructed on page 8. 2. Fill hopper with sanitary ice. Note: there is a timer in the control box that will activate the rotor in the ice bin every two hours. The amount of time that the rotor turns is factory set at 2 seconds, and is adjustable between one tenth of a second and 4 seconds. Agitation of the ice keeps it from fusing together after long periods in the bin. Ice hopper contains parts that can move at any time, and will cause injury if hands are in the way. Do not remove cover until the unit has been unplugged from the electrical power. 3. Plug the unit's power cord into an electrical outlet, if the unit has a lighted sign, it should come on. Dispense several containers of ice. FOR THE OPERATOR This section covers operating controls, daily pre-operation check, and unit operation. OPERATING CONTROLS - Units have either a lever or a push button. Lever: Ice will continue to be dispensed for as long as the lever is held in, or until the hopper is empty. Push Button: When the ice dispense button is pushed, ice will be dispensed for as long as the button is held in or until the hopper is empty. Daily Check 1. Make sure drip tray and grill are clean. 2. Remove cover and pour sanitary ice into the hopper. Do NOT use bagged ice directly from a freezer. The ice must be broken up in the bags first before adding to the hopper. Large chunks of ice can NOT be dispensed. HOT WATER The dispenser must always contain ice to have ice available for use. Keep the cover in place, and check the ice supply regularly during operating hours. 3. Keep sink clear of spilled ice. 4. At the end of the day: Remove the grill from the sink, clean the sink, grill and splash panel, make sure the sink drain is open by pouring hot water into the sink. Return the grill to the sink. October 1993 Page 5 IS100 and IS150 HOW IT WORKS The ice is stored in a hopper, and the hopper is sloped towards the front. At the front there is an angled rotor: when that rotor turns, it scoops the ice, lifts it to the top of the ice chute and drops it through that chute into the user's container. CUT AWAY VIEW ICE ROTOR DOOR UPPER ICE CHUTE ICE CHUTE October 1993 Page 6 IS100 and IS150 CLEANING AND SANITIZING The sink, grill and splash panel area should be cleaned daily. The ice storage system should be sanitized monthly. Daily: 1. Lift up and remove grill from sink. 2. Use soap, hot water, and a clean cloth to wash sink and splash panel; rinse with hot water, allowing plenty of hot water to run down the drain. 3. Wash the grill, then rinse with clean water. Place back in sink. 4. Clean all exterior surfaces of the unit with warm water and a sponge. Rinse out the sponge with clean water, wring excess water out of the sponge, and wipe off external surfaces of the unit. Wipe unit with a clean soft cloth. Do NOT use abrasive type cleaners. POUR HOT WATER DOWN SINK TO CLEAN OUT DRAIN. October 1993 Page 7 IS100 and IS150 CLEANING AND SANITIZING MONTHLY & INITIAL START UP: Sanitize the Ice Storage System.

Rotor will not turn 6. Relay for vend switch does not close during operation. CORRECTION 1. Fill hopper with ice 2. Check vend switch, replace if open 3. Check drive motor, replace if not working 4. Check/replace door and solenoid 5. Check hub of rotor 6. Check relays, replace if necessary. ELECTRICAL SEQUENCE Refer to the wiring diagram. Ice Vending: Ice is dispensed as long as the ice vend lever or push button is pushed, or until the hopper is empty of ice. · When the ice vend lever or push button is pushed, the vend switch closes, and makes a circuit to the coil of relay A. · When relay A is energized, relay A's contacts 6-9 and 7-4 close. Relay A's contacts 7-1 open. · When relay A's contacts 6-9 close, they make a circuit to the door solenoid, which opens the ice door. · When relay A's contacts 7-4 close, they make a circuit to the coil of relay B. · When relay A's contacts 7-1 open, the circuit to the timer is opened. · When relay B's coil is energized, it closes a circuit to the gearmotor, and the motor turns the rotor. Stand By: · Relay A's contacts 7-1 are closed and make a circuit to the timer. · The timer is energized when the unit is not dispensing. The timer switch will close for a few seconds every two hours. · When the timer switch is closed, it makes a circuit to relay B's coil. · When relay B is energized, it powers the gearmotor, and the rotor is turned.
