MAINTENANCE

WARNING: Before performing recommended main- tenance, be sure unit main power is off. Failure to do so may result in electrical shock or injury from rotating fan blades.

I. LUBRICATION

The outdoor fan motor is factory lubricated and requires no oil.

II. COMPRESSOR

The compressor contains factory oil charges; replace oil when lost. See Tables 1A and 1B for oil recharge. Recommended oil is Sontex 200LT for all units.

III. CLEANING COILS

Coil should be washed out with water or blown out with com- pressed air. Note that the blow-thru design causes dirt and debris to build up on the inside of the coils.

Clean coil annually or as required by location and outdoor air conditions. Inspect coil monthly and clean as required. Fins are NOT continuous through coil sections. Dirt and debris may pass through the first section, become trapped between the rows of fins, and restrict condenser airflow. Use a flashlight to determine if dirt or debris has collected between coil sections. Clean coil as follows:

1.Turn off unit power.

2.Use a garden hose or other suitable equipment to flush coil from the outside to remove dirt. Be sure to flush all dirt and debris from drain holes in the base of unit. Fan motors are waterproof.
