C. Preparing the Icemaker for Periods of Non-Use

NOTICE

•When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below to prevent damage.

•To prevent damage to the water pump, do not operate the icemaker with the control switch in the "SERVICE" position when the water tank is empty.

When the icemaker is not used for two or three days under normal conditions, it is sufficient to move the control switch to the "OFF" position. When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below.

1)Turn off the power supply, then remove the front panel.

2)Move the control switch on the control box to the "OFF" position. Confirm that the service switch is in the "CIRC." position.

3)Remove the front insulation, front frame, right side panel, and control box cover.

4)Disconnect the thermistor connector from the control board K3 (white) connector, then unplug the water pump connector at the water pump.

5)Wait 3 minutes, then move the control switch to the "ICE" position. Confirm that the bin control switch is closed and calling for ice. The green "BC CLOSED" LED on the control board should be on.

6)Once LED 1 and 2 on the control board energize (the order of the LEDs from the outer edge of the control board is 1, 4, 3, 2), close the inlet water supply line shut-off valve and open the inlet water supply line drain valve. Allow the line to drain by gravity.

7)Disconnect the harvest water valve hose in the evaporator section and blow out the water line to the harvest water valve using compressed air or carbon dioxide. See Fig. 4. This will clear water from the harvest water valve.

8)Move the control switch to the "OFF" position.

9)Move the service switch to the "WASH" position and the control switch to the "SERVICE" position.

10)Using the same hose as with the harvest water valve, blow out the wash valve using compressed air or carbon dioxide.

11)Move the service switch to the "CIRC." position and the control switch to the "OFF" position.

12)Remove the 4 hoses connected to the water tank. Allow the water tank and hoses to completely drain.

13)Move the control switch to the "ICE" position.

14)Using the fill/refill water valve hose, blow out the water line using compressed air or carbon dioxide. This will clear water from the fill/refill water valve.

15)Move the control switch to the "OFF" position.

16)Disconnect the float switch flush tube from the drain hose tee. Move the service switch to the "DRAIN" position and the control switch to the "SERVICE" position.
