CAUTION
To avoid electrical shock or
contact with moving parts,
make sure all switches are
in the "OFF" position and
the main power supply is
disconnected. Some
freezers have more than one
disconnect switch.
Blow dirt through the clogged areas
of the condenser.
Check the condensers periodically
with a light and continue the cleaning
treatment until the fins are clean.
B. Water Cooled Condensers
Depending on water conditions, the
condenser may require cleaning. Usually
a restricted flow of water resulting in a
high head pressure indicates a dirty
condenser. Flush the condenser with a
commercially available condenser
cleaner suitable for use on copper and
rubber components .
C. Beater and Condenser Fan
Motor Inspection
CAUTION
To avoid electrical shock
and contact with moving
parts, make sure all
selector switches are in the
"OFF" position and that the
main power supply is
disconnected. Some
freezers have more than
one disconnect switch.
The beater motors do not require lubri-
cation but should be inspected and
cleaned annually. Fan motors may need
a drop or two of non-detergent oil in the
oil port at each end of the motor.
