supplied with a complete charge of oil and requires no lubrication. The evaporator and condenser fan motors also have
permanently lubricated, sealed bearings. No lubrication of these items is required.
3-2. MECHANICAL LUBRICATION. The only mechanical items which may require lubrication are the conditioned air
supply and return louvers, the condenser air discharge louver and control linkages, and the devices which operate the
fresh air damper door. These points should be checked and lubricated, as necessary, during preventive 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. Be sure to wipe off all excess oil with a cloth or paper towel. These items are in an area of high
volume air flow 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 operation.
