Maintenance
Cleaning the Condenser
!
Disconnect electric power to the ice machine and
the remote condenser at the electric service switch
before 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.
! Caution
The condenser fins are sharp. Use care when
cleaning them.
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:
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.
! Caution
If you are cleaning the condenser fan blades with
water, cover the fan motor to prevent water
damage.

Warning
Removal from Service/Winterization
GENERAL
Special precautions must be taken if the ice machine
head section is to be removed from service for an
extended period of time or exposed to ambient
temperatures of 32°F (0°C) or below.
! 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.
Follow the applicable procedure below.
1. Disconnect the electrical power at the circuit breaker
or the electric service switch.
2. Turn off the water supply.
3. Disconnect and drain the incoming ice-making water
line at the rear of the ice machine.
4. Disconnect drain tubing (from the inlet to dump
valve) and drain water into container and discard.
5. Make sure water is not trapped in any of the water
lines, drain lines, distribution tubes, etc.
