Page 14: For The Plumber
GEM Models A/W Water Inlet: ●Air Cooled Models: The recommended water supply is clean, cold water. Use 3/8 inch O.D. copper tubing, connect to the 3/8 inch male flare at the back of the cabinet. Install a hand valve near the machine to control the water supply. -
Page 15: For The Electrician
GEM Models A/W Electrical Connections: Check the ice machine nameplate (located on the back panel) for the voltage requirements, and minimum circuit ampacity. The ice machine requires a solid chassis to earth ground. Connect the ice machine to its own electrical circuit so it is individually fused. Voltage variation must remain within the limitations, even under starting conditions. -

Page 21: Electrical Sequence
GEM Models A/W 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. -
Page 22: Operation: Water
GEM Models A/W Operation: Water Water enters the machine through the 3/8 inch male flare at the rear of the cabinet, goes to the water reservoir which it enters through the float valve. The water then goes out the bottom of the reservoir tank to the bottom of the evaporator. -

Page 24: Sanitizing And Cleaning
GEM Models A/W It is the USER’S RESPONSIBILITY to keep the ice machine and ice storage bin in a sanitary condition. Without human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. That chemical dissolves mineral build up that forms during the ice making process. -
Page 25: Bearing Maintenance
GEM Models A/W Bearing Maintenance: The bearing in the breaker should also be checked at least two (2) times per year. Switch the machine OFF and check the bearing. 1. Remove the chute cover. 2. Unscrew the ice sweep 3. Removing the water shed and unscrewing the breaker cover. -
Page 26: Sensor Maintenance
GEM Models A/W Bin Control Sensor: The bin control uses devices that sense light, therefore they must be kept clean enough so that they can “see”. At least twice a year, remove the bin control sensors from the base of the chute, and wipe the inside clean, as illustrated. -
Page 27: Air Cooled Maintenance
GEM Models A/W Clean the air cooled condenser: Air flow on this model is from front to back, so the inside of the ice machine will have to be available to clean the air cooled condenser. Use a vacuum cleaner or coil cleaner if needed. DO NOT use a wire brush. ●... -
Page 28: Auger Maintenance
GEM Models A/W Auger: In some areas, the water supply to the ice machine will contain a high concentration of minerals, and that will result in an evaporator and auger becoming coated with these minerals, requiring a more frequent removal than twice per year. If in doubt about the condition of the evaporator and auger, the auger can be removed so the parts can be inspected. -
Page 29: Service Diagnosis
GEM Models A/W Symptom No ice is made nothing operates. No ice, auger motor is turning. Possible Cause •Unit off due to no power •Unit off due to master switch in OFF position •Unit off due to low water level •Unit off due to ice level sensors. -
Page 30: Service Diagnosis
GEM Models A/W Symptom Unit makes ice, but very slowly Water leak. Excessive water use. Excessive ice meltage. Machine makes too much noise. Possible Cause •High discharge pressure because of a dirty condenser. •Low capacity because the auger and evaporator are coated with mineral scale. -
