Cleaning the Condenser 

Air-Cooled Condenser

(SELF-CONTAINED AND REMOTE MODELS)

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 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. 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 

Symptoms of restrictions in the condenser water circuit 
include:

•

Low ice production

•

High water consumption

•

High operating temperatures

•

High operating pressures

If the ice machine is experiencing any of these symptoms, 
the water-cooled condenser and water regulating valve 
may require cleaning due to scale build-up.

Because the cleaning procedures require special pumps 
and cleaning solutions, qualified maintenance or service 
personnel must perform them.

!

Warning

Disconnect electric power to the ice machine and
the remote condenser at the electric service switch
before cleaning the condenser.

!

Caution

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.
