9-1 Lubrication
Grease all fan bearings, fan motors, and pump motors that do not have permanently sealed bearings. Remove the grease relief plug (motors only) before adding grease. Failure to do so may dislodge the bearing grease retainer which will eventually cause bearing failure.
Lubricate components regularly, based only on the component manufacturer’s specifications for frequency and lubricant.
Compressors require a special scroll oil (Suniso 3GSA or equivalent); failure to use this oil when lubricating will void the
warranty.
9-2 Condenser Maintenance
Dirty condenser heat exchange surfaces reduce system capacity.
Inspect and clean as needed.
Remote Air-Cooled
Brush or vacuum light dirt accumulations. Avoid bending or damaging the fins. Heavy soil accumulations on the coil require professional steam cleaning by a qualified refrigeration service technician. Washing from the outside will only make matters worse.
Water-Cooled
Proper water treatment will greatly reduce cleaning intervals.
Remove dirt in the condenser tubes with a nylon tube brush. Mineral deposits can be removed by circulating Sterling Liquid
The refrigerant side is sealed and requires no routine maintenance.
