All outdoor wiring must be in rainproof conduit. All external wiring must conform to national, state and local electrical codes. The use of a licensed electrician is required to perform the electrical installation. GEM0650/0956/1256 Remote For the Electrician Completed Installation Roof Cut-A-Way A typical installation should generally appear as illustrated below. The best place for the remote condenser is above the ice machine, although other locations are permissible. GEM0650/0956/1256 Remote Final Check List * ___1. Is the ice system installed indoors in a location where air and water temperatures are controlled, and where they do not exceed the design limitations? * ___2. Is there an electrical service within sight of the installed machine? Has the voltage been checked, and compared to nameplate requirements? * ___3. Have all the plumbing connections been made and checked for leaks? * ___4. Has the machine and bin been leveled? * ___5. Is there a minimum of 6 inches clearance at the rear, left and right of the machine for proper service access? * ___6. Is the water pressure a minimum of 20 psig? * ___7. Has the machine been secured to the bin or dispenser? * ___8. Is there a water shut off valve installed near the machine? * ___9. Is the remote condenser installed per local codes, and in a place where it has adequate ventilation and minimal solar heat gain? * ___10. Has all shipping material and literature (inside front panel) been removed from the units? * ___11.Have the remote condenser and pre-charged lines been properly installed? * ___12. Has the electrical connection between the ice maker and condenser been made? * ___13. Verify that the master switch is in the OFF position. * ___14. Switch ON the electrical power. * ___15. Refer to the Pre-Start instructions, Page 15 Remote condenser secured? Roof Holes Sealed? Condenser Leveled? Power Supply? Plumbing? Machine Leveled? Pre-Start Inspection: 1. Remove the front and side service panels. 2. Check that any shipping blocks have been removed. 3. Inspect the interior of the ice machine for loose screws or wires. 4. Check that no refrigerant lines are rubbing each other. 5. Check that the fan blades turn freely (Remote Condenser). 6. Check that the refrigerant lines are properly installed. 7. Check that the electrical power has been on for at least 4 hours and that the compressor dome is warm. 8. Check that the unit is installed correctly according to the final check list. Start Up: 1. Go through the pre-start inspection. 2. Open the hand valve, observe that water enters the water reservoir, fills the tube from the water reservoir to the evaporator and then shuts off. (Water cooled only, Turn the water supply ON to the water cooled condenser). Check for leaks. 3. Open the King Valve. 4. Switch the master switch ON. The electrical start up sequence in automatic. a. There should be a short (15 second) delay before the gear motor starts and the liquid line opens. b. After the liquid line opens, the low pressure control will close and the compressor will start. 5. The remote condenser fan turns, and the condenser begins to discharge warm air. 6. The unit should soon be making ice, if desired; the low side pressure may be checked: it should be 32 psig +/- 2 psig. The air cooled discharge pressure will depend upon air and water temperatures, but should be between 200 psig and 280 psig. 7. There are no adjustments to make, so replace the panels. 8. Clean and/or sanitize the storage bin interior, wipe off the exterior with a clean, damp cloth. 9. 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. 10. 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. .Pump Down Control: A switch to control the compressor, depending upon low side pressure: closes at 30 PSIG and opens at 15 PSIG. .Evaporator: A vertical stainless steel tube, refrigerated and water filled. Utilizes a stainless steel auger. .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. Operates to turn on and off automatically as the level of ice in the bin changes. .Gear Motor: An oil filled, speed reduction gearbox, driving the auger. .Cleaning Drain Tube: When uncapped and lowered, drains the evaporator. .Compressor: The refrigerant...
