How The Electronic Cuber Works This section is intended for the technician. It is not necessary for the normal operation and maintenanceof the machine. Refrigeration System: The refrigeration system is similar to that of mostcommercial cube ice machines. Heat is removedfrom the water and discharged ...

How The Electronic Cuber Works Water System: Freeze: The water pump forces water to the top of theevaporators. The un-frozen water falls thru thecube deflectors and back into the reservoir. Aswater is turned into ice, the water level in thereservoir falls, and the machine will re-fill thereservoir o...

Additional Maintenance: Water Distributors It may become necessary to remove the waterdistributors from the top of the evaporator andclean (de-mineralize) them outside of the icemachine. 1. Remove front panels. 2. Push and release the OFF button. 3. Remove the evaporator covers. 4. Pull the tab at t...

Additional Maintenance: Inlet Water Valve Screen The inlet water valve has a screen on its inlet sideto keep debris from flowing into the valve. In somecases, this screen may become clogged orrestricted by debris build up. Check for the properwater flow: Flow rate is 2.7 G.P.M. 1. Remove front panel...

Additional Maintenance: Ice Sensors, Condenser The ice sensors use a system of infrared emittingand receiving components to sense the build up ofice in the bin. They are located at the bottom of theice outlet port. They must be free of mineral buildup to function properly. To check: 1. Remove front ...

Refrigerant 1. This ice machine uses R-404A or HP62 as arefrigerant. It has several unique characteristics. A. It is a near-azeotrope, and must be liquidcharged. B. It must use polyol ester refrigerant oil, and thatoil is very water absorbent. The system must notbe open for more than 15 minutes. C. ...

Liquid Charging Because R-404A is a near-azeotrope, only liquidrefrigerant can be used to recharge therefrigeration system. To do that may take somespecial techniques: 1. Use an electronic scale to measure the charge. 2. Place a drum or cylinder of R-404A on thescale, valve side up (most R-404A disp...
