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.
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.
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.
