AIR COOLED MAINTENANCE

Hazardous Moving

Parts.

Moving fan blade can cause personal injury. Disconnect electrical power before beginning.

Clean the air cooled condenser.

The air flow on this model is from front to back, so the inside of the machine will have to be available to clean the air cooled condenser. Use a vacuum cleaner or coil cleaner if needed. Do NOT use a wire brush.

A. Disconnect electrical power, and remove the filter. The filter may be cleaned or replaced.

B. Clean the condenser: the condenser may appear to be clean on the surface, but it can still be clogged internally. Check with a flash light from the front to see if light can be seen though the condenser fins. Reverse to reassemble.

Step 2: Remove the top portion of the fan shroud.

Step 3: Clean the condenser.

Step 1: Remove the top panel.
