Your new EP6 must be prepared for use prior to any operation with refrigerant. Follow the steps in the SET UP selection from MENU 3. This procedure can be used once at the time of initial set up. It will be deactivated at completion of set up. THE DEFAULT REFRIGERANT FOR SET UP IS R134a. 1. Fill the vacuum pump reservoir with 4 ounces of the oil provided by unscrewing the vent cap/dipstick assembly and pouring it into the fill tube. Add an additional 4 ounces after the motor starts in step 6 then replace the cap/dipstick assembly. 2. Determine which refrigerant you are going to use for the initial set up of the machine then select the appropriate storage tank. Connect the appropriate short hoses to the tank and machine (vapor to vapor/liquid to liquid), place the tank on the scale platform, open both tank valves then connect the tank float lead. 3. Connect the machine to power and turn the master power switch ON. Select MENU 4 then press the TANK SIZE button and select the tank size you are using (default is 30 lb.). Return to MENU 4 and press the DISPLAY MODE button. The next screen allows you to select your preferred weight (lbs & oz or Kg), pressure (PSI, KPa or mBAR) and temperature (Fahrenheit or Celsius) measurements to be displayed. Press the desired button for each option, select your desired measurement method then press the EXIT button to return to the main option screen. Repeat as necessary to select your preferred methods (default is lbs/oz, PSI and Fahrenheit). Once the measurement selection is completed, press EXIT to return to the main menu. Press the MENU button to return to MENU 3 and press the SET UP button. a. If you are setting up for R134a, connect the tank hoses to the corresponding machine and tank ports ( VAPOR to VAPOR/LIQUID to LIQUID ) and open both tank valves. b. If you are setting up for R12, PRESS and HOLD the CHANGE GATE button and move the access gate manually then connect the tank hoses to the corresponding machine and tank ports ( VAPOR to VAPOR/LIQUID to LIQUID ) and open both tank valves. DEFAULT SET UP IS R134a PRESS AND HOLD CHANGE GATE BUTTON TO MOVE GATE DISPLAY MODE CHANGE GATE CONTINUE EXIT 4. Press the CONTINUE button then press the R12 or R134a button on the following screen to confirm the refrigerant selected. You have the option to move the gate again at this time. CONFIRM GATE POSITION FOR REFRIGERANT SELECTED 7 8 CHANGE GATE R134a R12 5. When the button for the desired refrigerant is pushed, the next screen will be displayed. CONNECT TANK OPEN TANK VALVES REFRIGERANT ________ CONTINUE EXIT 6. Press the CONTINUE button to initiate the automatic preparation sequence. DO NOT interrupt this sequence. The service hoses may be connected to the machine while this operation is in process. 7. When the set up cycle is completed, the machine will stop and display the MAIN MENU. The set up function is now inoperative and cannot be used again. Your storage tank must be precharged now. PRECHARGE / RECHARGE STORAGE TANK IMPORTANT: Be sure that new tanks are in a vacuum before charging. 1. To precharge / recharge the tank with R134a, close the tank liquid valve and remove the short liquid hose from the tank and machine. Connect the R134a liquid hose to the low side service hose port on the machine and a virgin R134a bottle, open the valve on the virgin bottle, turn it upside down and set it in front of the machine. To precharge / recharge the tank with R12, close the liquid valve on the storage tank and leave the hose connected to the tank and machine. Connect the R12 low side service hose to the virgin R12 bottle, open the valve on the virgin bottle, turn it upside down and set it in front of the machine. 2. Press the RECOVER button and allow the machine to recover at least 7 lbs. of refrigerant into the storage tank. When the desired amount of refrigerant is precharged, close the valve on the virgin bottle and allow the machine to shut off automatically. 3. When done precharging / recharging with R134a, return the short liquid hose to the tank liquid and machine liquid ports and reinstall the low side service hose. YOUR EP6 IS NOW READY FOR USE 8 9 DISPLAY PROCEDURE When DISPLAY is selected the screen will change to the working display. This should be the first screen used when the machine is connected to an AC system to allow the technician to determine the A/C system's condition. This screen allows AC system checks and trouble shooting with the greater ability to locate and diagnose problems than allowed by normal gauge set methods. Tank Wgt _____ lbs _____ oz Function % Full _____ LO PRESS ____ Duct _____ HI PRESS ____ Amb _____ SYS PRESS _____ Sys TIME ___ Clutch VDC ____ EXIT TANK WEIGHT: Displays the gross weight of the tank. Empty tank weights: 16 lbs for 30 lb. capacity / 25 lbs for 50 lb. capacity. Note: This reading will display weight fluctuations when the motor is running. This will not affect the critical measurements. FUNCTION: Displays RECOVER when recovering and VACUUM when vacuuming. % FULL: Displays the storage tank % full based on empty weight plus refrigerant. LO: Displays the low side pressure of the AC system. HI: Displays the high side pressure of the AC system. SYS: Displays the internal machine pressure. CLUTCH: Displays the clutch voltage in DC volts. TIME: Displays timer in timed functions DUCT: Displays the temperature reading at the AC system duct when in use. SYS: Displays the temperature of the refrigerant in the machine and tank. AMB: Displays the temperature of air around the machine. EXIT: Return to the main menu or previous screen. AUTOMATIC ROUTINE PROCEDURE 9 10 NOTE: Before selecting automatic operation check the AC system for pressure and performance using the DISPLAY function. This will allow you to select the appropriate routine for the job being done. IMPORTANT: Before running the automatic routine, the vehicle AC system must be off. Connect both service hoses to vehicle. Open tank vapor valve and tank liquid valve. When AUTO is selected, the machine will perform the recovery, vacuum and charge functions automatically. An additional feature of the AUTO routine is the ability to perform the vacuum and charge functions even though a recovery function was not performed. Once the vacuum and charge information is entered and the recovery operation is activated, operator attendance or interference is not required unless an operation error or some other problem is identified and the alarm is activated. The machine checks for pressure in the AC system at the start of the routine and will start the recovery process or automatically advance to the vacuum and charge routine ...
