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 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.
Removing the Filter
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.
Removal from Service/Winterization
Special precautions must be taken if the ice machine is
to be removed from service for an extended period of
time or exposed to ambient temperatures of 0
°C (32°F)
or below.
1. Disconnect the electric power at the circuit breaker
or the electric service switch.
2. Turn off the water supply.
3. Remove the water from the water trough.
4. Disconnect the drain and the incoming ice-making
water line at the rear of the ice machine.
5. Make sure no water is trapped inside the ice
machine incoming water lines, drain lines,
distribution tubes, etc. Blow compressed air through
the line if necessary.
! 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.
REMOVE THE
FILTER
! Caution
If you are cleaning the condenser fan blades with
water, cover the fan motor to prevent water damage.
! Caution
If water is allowed to remain in the ice machine in
freezing temperatures, severe damage to some
components could result. Damage of this nature is
not covered by the warranty.
