5. Pour hot water into the evaporator ice exit opening. it will be necessary to use either a funnel or a container
with a spout. Fill the evaporator completely.
6. Drain the evaporator. Repeat steps 5 and 6 as required to insure that all of the ice in the evaporator is
melted.
7. Open the water supply valve and refill evaporator.
8. Consult the toubleshooting guide to determine cause of freeze-up before putting unit back in service.
SERVICE PROCEDURES
High Pressure Control
The high pressure control is factory set at 400 PSIG. To check the setting, install a refrigeration discharge pres-
sure gauge on the service port located on the compressor discharge line. Remove the front and right side pan-
els to access this port and high pressure control. Disconnect the electrical power to the condenser fan motor
leads in the control box. Run the icemaker to determine the control cut-out point. Adjust if necessary. this con-
trol is manual reset type; the reset lever is located behind the low pressure control next to the electric box on
top of the high pressure control. Push in to reset. If the icemaker will not run after the control has been reset
(with the refrigerant pressure less than 350 PSIG), replace the control. The adjustment screw is located on the
top of the control.
Bin Thermostat
1. The bin thermostat is located in the upper right rear corner of the unit under the cabinet flange.
2. To adjust the thermostat, remove the top plastic cover from the unit. The adjustment screw is located on
the top of the bin t’stat and is accessible through the hole in the cabinet flange. The factory setting is 35
°
F
cut-out / 41
°
F cut-in. Before adjusting, check that the adjustment screw is turned clockwise to the stop
position (CCW adjustment will raise the cut-out/cut-in temperatures).
WARNING: Electrical power is on for the service procedure in item 3. Avoid contact with
uninsulated parts in the control box.
3. The thermostat sensing bulb is located in the ice storage hopper on the upper left side wall. With the ad-
justment screw in the full cold position and no ice contacting the sensing bulb, check that the thermostat is
closed (terminals 1 and 2). With ice contacting the t’stat bulb, terminals 1 and 2 should be open to perform
this check, use a voltmeter connected between t’stat #2 and neutral to determine the correct operation.
4. To replace a defective thermostat, disconnect electrical power to the unit. Remove the sensing bulb from
the storage hopper (2 thumbscrews). Remove the t’stat from under the flange (2 screws) by disconnecting
the two electrical leads. Install the new control, being careful not to kink the capillary tubing (sensing bulb)
when routing it to the storage hopper.
