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. Remove the water from the icemaker water lines:
1) Turn off the power supply, then remove the front panel, right side panel, and control box
cover.
2) Move the control switch on the control box to the "OFF" position. Confirm the service
switch is in the "CIRC" position.
3) Close the icemaker water supply line shut-off valve and open the icemaker water supply
line drain valve. Allow the line to drain by gravity.
4) Attach a compressed air or carbon dioxide supply to the icemaker water supply line
drain valve.
5) Turn on the power supply, then move the control switch to the "ICE" position. Confirm
that the bin control switch is closed and calling for ice. The "POWER OK" LED should
be on and not flashing.
6) Blow the icemaker water supply line out using the compressed air or carbon dioxide
supply. This will clear water from the inlet water valve.
7) Move the control switch to the "OFF" position.
8) Disconnect the wash valve hose from the inlet water valve tee, then unplug the water
pump connector at the water pump. See Fig. 21.
9) Move the service switch to the "WASH" position, then move the control switch to the
"SERVICE" position.
10) From the wash valve hose, blow out the wash valve using the compressed air or carbon
dioxide supply. Reconnect the wash valve hose.
11) Move the service switch to the "CIRC" position, then move the control switch to the
"OFF" position.
12) Disconnect the float switch vent hose from the drain hose tee. Move the service switch
to the "DRAIN" position, then move the control switch to the "SERVICE" position.
13) From the drain hose tee, blow out the drain valve using the compressed air or carbon
dioxide supply. Reconnect the float switch vent hose.
14) Move the service switch to the "CIRC" position, then move the control switch to the
"OFF" position.
15) Turn off the power supply, then reconnect the water pump connector.
16) Close the icemaker water supply line drain valve.
