The water cooled discharge pressure should be a constant at about 245 psig. Note: The above pressures are for new, clean machines. You can expect to see some values higher, and some lower between different units. 6. There are no adjustments to make, so replace the panels. 7. Clean and/or sanitize the storage bin interior, wipe off the exterior with a clean, damp cloth. 8. Give the owner/user the service manual, instruct him/her in the operation of the unit, and make sure they know who to call for service. 9. Fill out the manufacturer’s registration and mail it to ICE-O-Matic. .Control Box: Contains the electrical controls that operate the machine. .High Pressure Cut Out Switch: An auto-reset switch sensing the high side refrigeration pressure. It will shut the machine off if the discharge pressure exceeds 450 psig. .Low Pressure Cut Out Switch: An auto-reset switch sensing the low side refrigeration pressure. It will disconnect power to the circuit board and shut down the machine if the low pressure falls too low. .Evaporator: A vertical stainless steel tube, refrigerated and water filled. Utilizes a stainless steel auger. .Compressor: The refrigerant vapor pump. .Water Reservoir: Float operated, it maintains the water level in the evaporator at a constant level, and it also contains the water level sensor. .Water Level Sensor: Senses if there is water in the reservoir to make ice out of. Will shut the ice machine off if there is no water in the reservoir. .Ice Discharge Chute: Directs the ice produced by the evaporator into the storage bin. .Ice Level Sensor: An “electronic eye”, it senses the presence of ice in the bottom of the discharge chute. .Gear Motor: An oil filled, speed reduction gearbox, driving the auger. .Drain Tube: When uncapped and lowered, drains the evaporator. .Condenser: Air or water cooled, where the heat removed in ice making is discharged. .Expansion Valve: The refrigerant metering device.

Switches loads on and off thru relays. (Reference Photo Below) .Potential Relay: The compressor start relay. .Mode (ON/OFF) Switch: Manual control for the machine.

It revolves with the auger to “sweep” the ice into the ice chute. .Breaker (Divider): Where the ice is compressed and much of the extra water is squeezed out of it before it is discharged into the bin. .Motor: A split phase motor that drives the gear reducer. .Thrust Bearings: As the ice is pushed up the evaporator, the auger is thrust down, and pressure from the auger thrust is taken up by this bearing. Text Box: Breaker/Divider Text Box: Evaporator Text Box: Bearing Text Box: Auger Text Box: Ice Sweep Text Box: Water Seal Text Box: Motor Electrical Sequence: There are 7 indicator lights on the control board: .WTR-OK: (Water OK) Green. Normal=Glowing. Glow when there is water in the reservoir. .PWR-OK: (Power OK) Green. Normal=Glowing. Glows when the power board has power and is functional. .Service: Red. Normally Off. .Freeze: Red. Normally glowing when making ice. .Bin Full: Red. Normally Off when making ice. .LED1: White. Located next to the Control Board’s Compressor Relay. Normally glowing when making ice. .LED2: White. Located next to the Control Board’s Auger Motor Relay. Normally glowing when making ice. If the machine is switched OFF at the mode switch, but otherwise ready to go, switching the mode switch ON does the following: .The PWR-OK light glows. .If there is water in the float reservoir, the WTR-OK light glows. .After 10 seconds the Freeze, LED1 and LED3 lights glow and the machine starts up. Start Up: .The compressor relay and auger motor relay become energized, connecting power to the windings of the auger motor and contactor coil. .The contactor is energized, connecting power to the compressor, and the compressor starts. .As ice is made it passes between the ice level sensors but because it is not a continuous stream it only interrupts the sensor’s inf...
