CLEANING THE CONDENSER
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.
1. The washable aluminum 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: Blow
compressed air through the condenser fins from the
inside. Be careful not to bend the fan blades.
4. Use a commercial condenser coil cleaner. Follow
the directions and cautions supplied with the
cleaner.
5. Straighten any bent condenser fins with a fin comb.
6. 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.
Water-Cooled Condenser and
Water Regulating Valve
The water-cooled condenser and water regulating valve
may require cleaning due to scale build-up.
Low ice production, high water consumption and high
operating temperatures and pressures all may be
symptoms of restrictions in the condenser water circuit.
Because the cleaning procedures require special pumps
and cleaning solutions, they must be performed by
qualified maintenance or service personnel.
! Warning
Disconnect electric power to the ice machine at
the electric service switch before cleaning the
condenser.
! Warning
The condenser fins are sharp. Use care when
cleaning them.
! Caution
If you are cleaning the condenser fan blades with
water, cover the fan motor to prevent water
damage.
