Page 14: Maintenance
MAINTENANCE Compressor The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should provide years of satisfactory operating service. Under no circumstances should the access fitting covers be loosened, removed or tampered with. Breaking of seals on compressor access fittings during warranty period will void warranty on hermetic system. Recharging ports are provided for the ease and convenience of reputable refrigeration repair service personnel for recharging the air conditioner. -
Page 15: Condenser And Evaporator Air Movers
Condenser and Evaporator Air Movers Impeller motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life of the motor. If one of the condenser impeller motors (ambient impellers) should fail, it is not necessary to remove the air conditioner from the cabinet or enclosure to replace the blower. -
