User manual BOSCH KAD 62V40/02 SHORT INSTRUCTIONS

[. . . ] The ice making sections are designed for use indoors in a controlled environment. The remote compressor packages and condensers are designed to operate outdoors. Operational Limitations: Minimum Air Temp (IMS) Air Temp (CU) Water Temp Water Pressure Voltage (IMS) Voltage (CU) 50oF -20oF. 20 psi 104 198 o Do Not operate the machine in conditions beyond these limitations. [. . . ] The compressor is on for the full cycle, the pump is off and then on, the purge valve is open and then closed, the inlet water valve is closed, opens and recluses. The vapor and condenser by-pass valves are open during the entire harvest cycle. A manually initiated rinse flushes the system. 8 9 7 6 5 4 3 2 1 PUSH BUTTON CONTROL SWITCHES INDICATOR LIGHTS: BIN FULL FREEZE HARVEST CLEAN OFF DIAGNOSTIC LIGHTS: WATER REFRIGERATION Controller Lights and Push Buttons September 2003 Page 27 Eclipseä 1300, 1600 Initial Start Up - 1300 and 1600 Pre Start A soak-out period of four hours is optional for this system. If desired, powering the compressor unit for four hours prior to start up allows the crankcase heater to warm up the oil in the compressor. Connect power to the condensing unit and move its toggle switch to Run or On. Observe the lights on the controller: After a few minutes ice will begin to form on the evaporators. When enough ice has formed to nearly empty the water reservoir, the controller will refill the reservoir. The next time the water level drops that far, the ice is ready for release and the Controller will initiate a Harvest cycle. ·The Freeze light goes out and the Harvest light switches on. opens. ·The vapor inlet valve in the ice making section ·In the CP unit, the condenser by-pass valve opens and the liquid inlet valve closes ·All flash on as the power supply is reconnected. ·The two red lights blink for 20 seconds while some green lights are on. Note: If the light pattern does NOT match ­ do not start the machine. If the machine is on, push and hold the OFF button for more than 3 seconds, then release it. Push and hold the OFF button for more than 3 seconds (just until all lights flash on) then release it. They should have all flashed once, then certain ones will have turned on to indicate which purge level the machine is set at. There are 5 levels of purge available: Cube Size: Cube size is fixed and cannot be adjusted. Thermostatic Expansion Valve: The TXV is not adjustable, do not attempt to adjust it. If there was a problem during Initial Start Up: If an error light came on, check the following. A water error could have been determined by the AutoIQ Controller if the inlet water valve does not fill the reservoir, or if the water pump does not start and lower the water level. A refrigeration error could have been determined by the AutoIQ Controller if the water temperature did not drop during the freeze cycle. The controller will next check the compressor discharge temperature, If the discharge temperature is too low, the refrigerant error light will be switched on, and the machine will Shut Down. Note: Reset and restart the machine by pushing and releasing the Off push button switch, and then pushing and releasing the freeze push button switch. ·1. Maximum Purge is when All 5 lights are ON. Use for extreme water conditions. ·2. [. . . ] Place an object between the ice sensors, after 5 seconds the Bin Full light will be glowing steadily, if not check operation of sensors by unplugging #4. Bin Full light will go on after 5 seconds, If not, replace controller. If the light does go on, replace ice sensor set. No ice released to bin No ice released, vapor inlet valve does not open Ice outlet blocked - check for obstruction Check coil for continuity, if open replace coil Check for 24 volts to coil during harvest, if non, check at controller Check low side pressure, if pressure does not rise during harvest, and valve is electrically OK, replace vapor inlet valve September 2003 Page 41 Eclipseä 1300, 1600 Service Diagnosis Problem or Symptom Low capacity Possible Cause Dirty condenser Air temperature intake to condenser very high Water temperature intake to ice making section very high Probable Correction Clean condenser Re-orient condenser to avoid hot air intake Check for hot water supply to ice machine due to mal-functioning or non-existent hot water check valve at dishwashing sink False bin full - bin full light is ON and the Unplug thermostat from terminal 7 and bin is not full check controller. Bin full light must go out within 4 minutes or ice sensors need checking. [. . . ]
