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
