LUBRICATION INSTRUCTIONS
GENERAL
The refrigerant compressor and its drive motor are hermetically sealed in a canister. The compressor is supplied with a
complete charge of oil and requires no lubrication. The evaporator and condenser fan motors have permanently lubricated,
sealed bearings. No lubrication of these items is required.
MECHANICAL LUBRICATION
The only mechanical items that require lubrication are the conditioned air supply and return louvers, the condenser air
discharge louver and control linkages, and the devices that operate the fresh air damper door. These points should be checked
and lubricated as necessary, during preventative maintenance service. A few drops of light oil should be applied to pivot
points, bearing surfaces, and linkages to prevent or eliminate stiffness or binding. Wipe off all excess oil with a cloth or paper
towel. These items are in an area of high volume airflow and excess oil will tend to attract and accumulate dust particles from
the passing air. Graphite may be used as an alternate lubricant during extreme cold weather conditions.
