5 166240009 INST ALLA TION INSTRUCTIONS Y ou will get better service from the ice machine, longer life and greater convenience if you choose its location with care. Here are a few points to consider: 1. Select a location as close as possible to where you are going to use the ice.
6 166240009 14. T urn machine on and check for proper voltage and amp draw on the entire unit as well as components such as the gearmotor and fan motor . 15. Check refrigerant circuit and all plumbing connections for leaks, etc. 16. Check bin thermostat or mechanical shut – of f for proper operations.

9 166240009 TYPICAL W A TER CIRCUIT The supply water enters the float chamber through a small orifice. The water level rises and lifts the buoyant float with it.
10 166240009 TYPICAL REFRIGERANT CIRCUIT Heat always flows from hot to cold and therefore, the ” heat load ” supplied to the evaporator section by water gives up its heat to the refrigerant which is at a temperature below the freezing point of water .
11 166240009 ELECTRICAL CIRCUIT CIRCUIT DESCRIPTION As the manual on – off – circuit breaker switch is pushed to ” on ” , an electrical circuit is completed to the gearmotor via the circuit breaker gearmotor overload, power relay / contactor , gearmotor delay thermostat and the bin thermostat.

20 166240009 MAINTENANCE THE FOLLOWING MAINTENANCE SHOULD BE PERFORMED A T LEAST EVER Y SIX MONTHS ON FLAKED ICE MACHINES: 1. Check power supply with machine running for proper voltage. 2. Check water level in the float tank reservoir . W ater level should be maintained at the top of the evaporator .
21 166240009 SANITIZING AND CLEANING PROCEDURE 1. T urn switch to ” OFF ” to stop unit. 2. Remove top cabinet panel. CAUTION: Hazardous moving parts. Do not operate unit with panel removed. 3. Mix sanitizing solution by using 0.5-ounces of household liquid bleach (such as Hi-Lex or Chlorox) to one gallon of potable water .
22 166240009 W A TER TREA TMENT During the freezing process, as water passes under the freezing plate, the impurities in the water have a ten- dency to be rejected and the plate will freeze only the pure water . However , the more dissolved solids in the water , the more troublesome the freezing operation will be.
23 166240009 TROUBLESHOOTING T rouble Probable Cause Remedy UNIT WILL NOT RUN A. On – off switch in ” of f ” position. A. T urn switch to ” on ” . B. Defective on – off switch. B. Check and replace. C. Blown fuse. C. Replace fuse and check for cause of blown fuse.
24 166240009 T rouble Remedy Probable Cause MAKING WET ICE. A. Surrounding air temperature too high. A. Correct or move unit B. High water level in float reservoir . B. Lower water level, see step 2, page 5 C. Dirty condenser . C. Clean condenser D. Faulty compressor .
25 166240009 T rouble Remedy Probable Cause UNIT OFF OR TRIPS CIRCUIT BREAKER. A. Ice jams up in evaporator shell. A. Clean inside surface of evaporator shell. B. Bin thermostat will not shut – off machine. Set too cold. B. Check and adjust or replace .
26 166240009 T rouble Remedy Probable Cause UNIT GOES OFF OR TRIPS CIRCUIT BREAKER. (CONT ’ D) L. Plugged expansion valve, or capillary tube causing low back pressure. L. Check back pressure, replace valve or capillary tube. Evacuate and re – charge system, replace drier – strainer .
