Cleaning the Condensing Unit

Perform the following procedure monthly to maintain proper and
efficient operation as well as prevent malfunction when
operating in COLD mode .
1. Remove and clean both sides of the louvered or grill-style
panels that are installed in the ventilation openings. Dirt
and dust build-up in the panels can restrict air flow to the
condensing unit and cause over-heating.
2. Clean the condenser coil cooling fins. Dirt, dust, and lint
build-up in the cooling fins will prevent proper cooling of the
refrigerant in the refrigeration system. This buildup will cause
inefficient operation and can lead to unit failure. Use the
following methods to clean the condenser coil cooling fins:
• Vacuum the cooling fins.
• Brush the cooling fins vertically using a condenser coil
brush. NOTI E: Use caution when brushing the
cooling fins, they are delicate and can be bent
easily. DO NOT use a wire brush.
This unit must be serviced by qualified personnel only.
Service by unqualified personnel may lead to electric
shock or burn.
