B. Maintenance
IMPORTANT
This icemaker must be maintained individually, referring to the instruction
manual and labels provided with the icemaker.
1. Stainless Steel Exterior
To prevent corrosion, wipe the exterior occasionally with a clean and soft cloth. Use a
damp cloth containing a neutral cleaner to wipe off oil or dirt build up.
2. Dispenser or Storage Bin Unit and Scoop
• Wash your hands before removing ice. Use the plastic scoop provided (accessory).
• The dispenser or storage bin is for ice use only. Do not store anything else in the bin.
• Keep the scoop clean. Clean it by using a neutral cleaner and rinse thoroughly.
• Clean the bin liner by using a neutral cleaner. Rinse thoroughly after cleaning.
3. Condenser
Check the condenser once a year, and clean the coil if required by using a brush or
vacuum cleaner. More frequent cleaning may be required depending on the location of
the condensing unit.

C. Preparing the Icemaker for Long Storage
CAUTION
When the icemaker is not used for two or three days under normal conditions, it
is sufficient to only move the control switch to the "OFF" position. When storing
the icemaker for extended time or in sub-freezing temperatures, turn the water
off and drain out all water from the water lines and remove the ice from the
dispenser or storage bin. The dispenser or storage bin should be cleaned and
dried. Drain the icemaker water hoses using air or carbon dioxide to prevent
damage at sub-freezing temperatures.
To drain all water from the icemaker, follow the steps below. See Fig. 11.
1) Remove the front panel.
2) Move the control switch to the "OFF" position. Confirm that the service switch is in the
"OFF" position.
3) Remove the front insulation, front frame, right side panel, and control box cover.
4) Disconnect the thermistor from the K3 connector on the control board, and 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 potable water supply line shut-off valve
and open the potable 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. 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 "OFF" position and the control switch to the "OFF"
position.
12) Remove the 4 hoses connected to the water tank. Allow the tank and hoses to
completely drain.
13) Move the control switch to the "ICE" position.
14) Using the fill water valve hose, blow the water line out using compressed air or carbon
dioxide. This will clear water from the fill water valve.
15) Move the control switch to the "OFF" position.
25
16) Disconnect the float switch vent hose from the drain hose tee. Move the service switch
to the "DRAIN" position and the control switch to the "SERVICE" position.
17) From the tee on the drain hose, blow the drain water valve out using compressed air or
carbon dioxide.
18) Move the service switch to the "OFF" position and the control switch to the "OFF"
position.
19) Reconnect the thermistor to the K3 connector on the control board. Reconnect the
water pump connector.
20) Close the potable water supply line drain valve.
21) Remove all ice from the dispenser or storage bin and clean the bin.
22) Turn off the power supply.
23) Replace all removed parts and panels in their correct positions.
