Condenser and Evaporator Air Movers
Fan motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life of the
fan.
Operation of the air conditioner in areas containing airborne
caustics or chemicals can rapidly deteriorate filters, condenser
coils, blowers and motors, etc. Contact Pentair Technical Products
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.
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.
