[. . . ] Remove two screws and the control box cover. OPEN the water supply line shut off valve. Open the "king" valve on the receiver. Inside the control box is the shaft of the timer and switch assembly. Rotate the shaft of the timer and switch assembly clockwise to start the timer. The timer starts when the actuator arm on the microswitch drops off outer cam into cam slot. Move the Master ON-OFF switch to the ON position. If needed, rotate the timer clockwise a to begin another "harvest" cycle to add more water to the reservoir. Note: Some water will drip off the evaporators, this is normal and there will be a reduction in water dripping after several cycles of ice. When the sump has filled, move the compressor ON-OFF toggle switch, to the ON position. Check operation of the freezing cycle: As the icemaking process begins the water temperature falls and very shortly ice begins to form. Thoroughly explain to the owner/user the significant specifications of the icemaker, the start up and operation, going through the procedures in the cleaning instructions. Answer all questions about the icemaker by the owner; and inform the owner of the name and telephone number of the local authorized WHIRLPOOL Distributor, or service agency. BIN ICE LEVEL SWITCH March 1994 Page 16 WRF532SMBW FREEZING CYCLE OPERATION Water from the sump assembly is pumped to the water distributor system at the top of each evaporator plate. From the water distributor the water cascades by gravity over all cells of the plate and to the sump assembly below. At the beginning of the freezing cycle, the electrical circuit is completed to the compressor and the water pump. The water pump operates continuously, through both the freezing cycle and the harvest cycle. During the freezing cycle, the hot gas solenoid valve is CLOSED and the water inlet solenoid valve is CLOSED. When the ice cubes are partially formed, the cube size control will sense the temperature at which it is preset to CLOSE. This will complete the electrical circuit to the timer. The timer then controls the remainder of the freezing cycle. The timer will keep the icemaker operating in the freezing cycle for a selected length of time. This will give the ice cubes time to fully form.

The refrigeration system only be done when it is certain remove the core cap. [. . . ]
