Ice Machine Inspection
Check all water fittings and lines for leaks. Also, make
sure the refrigeration tubing is not rubbing or vibrating
against other tubing, panels, etc.
Do not put anything (boxes, etc.) in front of the ice
machine. There must be adequate airflow through and
around the ice machine to maximize ice production and
ensure long component life.
Exterior Cleaning
Clean the area around the ice machine as often as
necessary to maintain cleanliness and efficient
operation.
Sponge any dust and dirt off the outside of the ice
machine with mild soap and water. Wipe dry with a
clean, soft cloth.
A commercial grade stainless steel cleaner/polish can
be used as necessary.
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.
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 32
°
F (0
°
C)
or below.
Follow the applicable procedure 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 and drain the incoming ice-making water
line at the rear of the ice machine.
5. Blow compressed air in both the incoming water and
the drain openings in the rear of the ice machine
until no more water comes out of the inlet water lines
or the drain.
6. Make sure water is not trapped in any of the water
lines, drain lines, distribution tubes, etc.
!
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.
!
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.
