Preparing The Icemaker For Long Storage - Hoshizaki KMD-850MAH Service Manual

3. Air Filters (air-cooled model only)
Plastic mesh air filters remove dirt and dust from the air, and keep the condenser from
getting clogged. As the filters get clogged, the icemaker's performance will be reduced.
Check the filters at least twice a month. When clogged, use warm water and a neutral
cleaner to wash the filters.
4. Condenser (air-cooled and remote air-cooled models only)
Check the condenser once a year, and clean if required by using a brush or vacuum
cleaner. More frequent cleaning may be required depending on location.
C. Preparing the Icemaker for Long Storage
When shutting off the icemaker for an extended time, drain out all water from
the water line and remove the ice from the storage bin/dispenser unit. The bin/
dispenser should be cleaned and dried. Drain the icemaker to prevent damage
to the water supply line at sub-freezing temperatures, using air or carbon
dioxide. Shut off the icemaker until the proper ambient temperature is resumed.
When the icemaker is not used for two or three days, it is sufficient to only move the control
switch to the "OFF" position, unless the icemaker will be at sub-freezing temperatures.
1. On water-cooled model only, first remove the water from the water-cooled
condenser:
1) Turn off the power supply and remove the front panel and right side panel.
2) Close the condenser water supply line shut-off valve and open the condenser water
supply line drain valve.
3) Attach a compressed air or carbon dioxide supply to the condenser water supply line
drain valve.
4) Open the water regulating valve by using a screwdriver to pry up on the spring retainer
underneath the spring. While holding the valve open, blow out the condenser using the
compressed air or carbon dioxide supply until water stops coming out.
5) Close the condenser water supply line drain valve and replace the right side panel in its
correct position.
2. Remove the water from the icemaker water supply line:
1) If you have not already done so, turn off the power supply and remove the front panel.
2) Close the icemaker water supply line shut-off valve and open the icemaker water
supply line drain valve.
3) 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) Make sure at least 3 minutes have elapsed since you turned off the power supply.
Make sure the control switch is in the "ICE" position. Replace the front panel in its
correct position and turn on the power supply.
