SERVICE AND MAINTENACE
CAUTION
BEFORE PERFORMING RECOMMENDED MAINTENANCE
AND SERVICE, BE SURE UNIT MAIN POWER SWITCH IS
TURNED OFF. FAILURE TO DO SO MAY RESULT IN
ELECTRIC SHOCK OR INJURY FROM ROTATING FAN
BLADE.
CLEANING COIL – Coil should be washed out with water or blow
out with compressed air. The draw thru design causes dirt and
debris to built up on the outside of the coils. Clean coil as follows:-
1) Turn off unit power.
2) Using a water hose or other suitable equipment, flush coil from
the inside to remove dirt (see Fig. 10). Be sure to flush all dirt
and debris from drain holes in base of unit. Fan motor is water
proof but it is more safe to cover or wrap motor shell with
plastic sheet (or plastic bag) to prevent water from getting
inside.
Clean coil semi-annually or as required. Fins are not continuous
through coil sections. Dirt and debris may pass between the row of
fins and become trapped between the row of fins and restrict
condenser air flow. Use a flashlight to determine if dirt or debris has
collected between coil section.
