MAINTENANCE
COMPRESSOR
The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should
provide 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.
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.
EVAPORATOR BLOWER
Blower motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life
of the motor.
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.
FREEZING AND DRAINING THE SYSTEM
If the unit is to be shipped to, or stored in an area that experiences climatic extremes, care must be taken to fully
drain the unit to avoid freezing. The location of the drain is shown in the DIMENSIONAL DRAWING on page 4.
To completely drain the unit, it is recommended that 100 psi maximum compressed air be applied to the water
inlet, while lifting the spring of the valve with a screwdriver to allow free passage of water. An alternate means
would be to start the air conditioner and allow the refrigeration system pressure to open the valve while air
pressure is applied to inlet.

The air conditioner can be severely damaged by freezing if not
properly drained. damage due to freezing is not covered by the
