How to clean the condenser and winterize.
Condenser cleaning
The condenser is like the radiator on a car, it has
fins and tubes that can become clogged with dirt
and lint. To clean:
1. Remove the kickplate and front service panel.
Note: Outdoor operation can lead to rapid build up
of debris, such as leaves and other vegetation. The
condenser will need to be frequently checked for
debris. Clean it whenever the fins are obstructed.
2. Locate the condenser surface.
3. Vacuum the surface, removing all dust and lint.
Caution: Do not dent the fins.
4. Return the kickplate and front service panel to
their original positions. Fasten them to the cabinet
using the original screws.
Winterizing
1. Clean the ice making system.
2. Open the door and push and release the On/Off
switch to turn the machine off.
3. Turn off the water supply.
4. Drain the water reservoir by removing the rubber
cap under the reservoir - it's near the back wall of
the ice storage bin.
5. Disconnect the incoming water line at the inlet
water valve.
6. Open the door, push and release the on/off
switch to turn the machine on.
7. Blow air through the inlet water valve until water
stops flowing out; a tire pump could do the job.
8. Drain pump models should have about 1/2
gallon of RV antifreeze (propylene glycol) poured
into the ice storage bin drain.
Note: Automotive antifreeze must NOT be used.
9. Switch off and unplug the machine.
