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.
