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. The condenser blower is mounted on its own

bulkhead and is easily accessible by removing the front cover.

Operation of the air conditioner in areas containing airborne

caustics or chemicals can rapidly deteriorate filters, condenser

coils, blowers and motors, etc. Contact Pentair Equipment

Protection for special recommendations.

CAUTION

REFRIGERANT LOSS

Each air conditioner is thoroughly tested prior to leaving the factory to insure against refrigeration leaks. Shipping

damage or microscopic leaks not found with sensitive electronic refrigerant leak detection equipment during

manufacture may require repair or recharging of the system. This work should only be performed by qualified

professionals, generally available through a local, reputable air conditioning repair or service company.

Should the refrigerant charge be lost, access ports on the suction and discharge sides of the compressor are

provided for recharging and/or checking suction and discharge pressures.

Refer to the data on the nameplate which specifies the type of refrigerant and the charge size in ounces.

Before recharging, make sure there are no leaks and that the system has been properly evacuated into a deep

vacuum.
