Preparing The Appliance For Periods Of Non-Use - Hoshizaki DCM-300BAH Instruction Manual

IV. Preparing the Appliance for Periods of Non-Use
When storing the appliance for an extended time or in sub-freezing temperatures,
follow the instructions below to prevent damage.
When the appliance is not used for two or three days under normal conditions, it is
sufficient to move the power switch to the "OFF" position. When storing the appliance for
an extended time or in sub-freezing temperatures, follow the instructions below.
1. Remove the ice from the ice storage bin, drain the water system, and remove the
water from the icemaker water supply line:
1) Close the icemaker water supply line shut-off valve and open the icemaker water supply
line drain valve.
2) Move the control switch to the "OFF" position, pause momentarily, then move to the
"DRAIN" position. Allow the water system to drain for 5 minutes.
Note: a) A momentary pause in the "OFF" position is necessary to de-energize the
control board when moving the control switch between "ICE" and "DRAIN."
Otherwise there is a delay of several minutes before the new selection takes
effect.
b) If the control switch is left in the "DRAIN" position for 10 minutes or more, a
2-beep alarm sounds every 5 seconds. Move the control switch out of the
"DRAIN" position to clear the alarm.
3) Move the dispense mode switch to the "CONTINUOUS" position, then dispense all of
the ice from the ice storage bin.
4) Attach a compressed air or carbon dioxide supply to the icemaker water supply line
drain valve.
5) While engaging the water dispense switch, blow out the water dispense valve using the
compressed air or carbon dioxide supply. After blowing out the water dispense valve,
leave the compressed air or carbon dioxide supply flowing. Move the control switch to
the "OFF" position, pause momentarily, then move to the "ICE" position to open the inlet
water valve and briefly blow out the inlet water valve. After blowing out the inlet water
valve, move the control switch to the "OFF" position.
6) Close the icemaker water supply line drain valve.
7) Turn off the power supply, then remove the front panel and move the power switch to the
"OFF" position.
8) Remove the ice storage bin cover. Clean the ice storage bin liner and the ice storage bin
cover using a neutral cleaner. Rinse thoroughly after cleaning. Replace the ice storage
bin cover and the front panel in their correct positions.
Note: If your unit has a water-cooled condenser, leave the front panel off and go to the
next section.
