CLEANING THE 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.
1. The washable foam filter on self-contained 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.
! Warning
Disconnect electric power to the ice machine at the
electric service switch before cleaning the
condenser. The condenser fins are sharp. Use care
when cleaning them.

Warning
If you are cleaning the condenser fan blades with
water, cover the fan motor to prevent water damage.
