7	Routine Maintenance

7-1 Lubrication

Every three months, grease all fan motors and pump motors that do not have permanently sealed bearings. Remove grease relief plug (motors only) before adding grease. Failure to do so may result in dislodging the bearing grease retainer, eventually causing bearing failure.

Compressors are hermetically sealed; no oiling is required.

7-2 Condenser Maintenance

Dirty condenser heat exchange surfaces reduce system capacity.

Brush or vacuum light dirt accumulations. Avoid bending or damaging the fins. Heavy soil accumulations on the coil require professional steam cleaning; washing from the outside only makes matters worse.
