Maintenance

Cleaning the Condenser

n
Disconnect electric power to the ice machine at the
electric service switch before performing maintenance on
equipment.

AIR-COOLED CONDENSER

A dirty condenser restricts airflow, resulting in excessively
high operating temperatures. This reduces ice production
and shortens component life.
Clean the condenser at least every six months.
1. Remove Plastic Front Grill removing two Phillips head
screws. Clean Grill openings before replacing.
2. Clean the outside of the condenser with a soft brush
or a vacuum with a brush attachment. Clean from top
to bottom, not side to side. Be careful not to bend the
condenser fins.
3. Shine a flashlight through the condenser to check for dirt
between the fins. If dirt remains:
A. Blow compressed air through the condenser fins. Be
careful not to bend the fan blades.
B. If dirt or grease remains between fins, consult your
service representative.
n
The condenser fins are sharp. Use care when cleaning
them.
