MAINTENANCE
COMPRESSOR
The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should
provide many years of satisfactory operating service.
Should the refrigerant charge be lost, recharging ports (access fittings) on the suction and discharge sides of the
compressor are provided for recharging and/or checking suction and discharge pressures.
NOTE:
Under no circumstances should the access fitting covers be loosened, removed or tampered
with. Removing or tampering of the access fitting covers voids the warranty.
Recharging ports are provided for the ease and convenience of reputable refrigeration repair service personnel
for recharging the air conditioner - see Refrigerant Loss.
EVAPORATOR BLOWER
Blower motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life
of the motor.
REFRIGERANT LOSS
Your Hoffman cooling air conditioner was thoroughly tested before leaving the factory to insure against
refrigeration leaks. Shipping damage or microscopic leaks not found with sensitive electronic refrigerant leak
detection equipment during manufacturing may require repair and recharging of the system. This work should
be performed by qualified professionals, generally available in any reputable air conditioning repair or service
company in your local area.
Refer to the data on your nameplate which specifies the type of refrigerant and the charge size in ounces and
grams.
Before recharging, make sure there are no leaks and the system has been properly evacuated by deep vacuum.
