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. Follow the steps below.

Warning
The condenser fins are sharp. Use care when cleaning
them.
1. The washable aluminum filter on self-contained air-
cooled ice machines is designed to catch dust, dirt,
lint and grease. This helps keep the condenser clean.
Clean the filter with a mild soap and water solution.
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
from the inside. Be careful not to bend the fan
blades.
B. Use a commercial condenser coil cleaner. Follow
the directions and cautions supplied with the
cleaner.
4. Straighten any bent condenser fins with a fin comb.
5. Carefully wipe off the fan blades and motor with
a soft cloth. Do not bend the fan blades. If the fan
blades are excessively dirty, wash with warm, soapy
water and rinse thoroughly.
