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.
