3. Air Filter (air-cooled model only)
The plastic mesh air filter removes dirt and dust from the air, and keeps the condenser
from getting clogged. As the filter gets clogged, the icemaker’s performance will be
reduced. Check the filter at least twice a month. When it is clogged, use warm water
and a neutral cleaner to wash the filter.
4. Condenser (air-cooled model 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 the location of the
icemaker.
C. Preparing the Icemaker for Long Storage
IMPORTANT
When shutting off the icemaker for an extended time, drain out all water from
the water lines and remove the ice from the storage bin. The storage bin should
be cleaned and dried. Drain the icemaker and water-cooled condenser (if
applicable) using air or carbon dioxide to prevent damage to the water supply
lines at sub-freezing temperatures. 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.
To drain all water from the icemaker, follow the steps below.
1) Remove the front panel, top panel and insulation panel.
2) Move the control switch on the control box to the OFF position.
3) Wait 3 minutes, then move the control switch to the ICE position.
4) Allow the icemaker to complete the one minute fill cycle (LED 4 is on), then move the
switch back to the OFF position.
5) Close the potable water supply line shut-off valve and open the potable water supply
line drain valve.
6) Allow the line to drain by gravity.
7) Move the control switch to the ICE position.
8) Blow the potable water supply line out using compressed air or carbon dioxide. This will
clear water from the freeze water valve.
9) Allow the machine to cycle from the one minute fill cycle to the initial harvest cycle
(LEDs 1, 4 and 2 are on). Blow the potable water supply line out using compressed air
or carbon dioxide. This will clear water from the harvest water valve.
10) Move the control switch to the OFF position.
11) Disconnect the suction hose to drain the water. See Fig. 1.
12) Disconnect the upper hose from the harvest water valve. Move the control switch to
the WASH position and quickly blow out the hose line using compressed air or carbon
dioxide. This will clear water from the wash valve.
