B. Blowers

The design life of the blowers used in all Kooltronic Air Conditioners is substantially in excess of
20,000 hours. All Kooltronic condenser and evaporator blowers are equipped with automatic-reset
thermal overload protectors.

CAUTION

If field replacement of a blower motor is necessary, most blower assemblies, including the mounting
plate, are readily removable. Each of the blower mounting plates is held to the air conditioner cabinet
structure by screws and nuts. For installation of the replacement blower, electrical connections
may be broken at the terminal block, or power leads may be cut and appropriately spliced together. 

C. Compressor

All Kooltronic compressors are approved by UL and CSA, and require no maintenance. They are
hermetically sealed and charged at the factory, and equipped with automatic-reset thermal overload
protectors.

If the compressor fails, it is strongly recommended that the air conditioner be returned to Kooltronic
for service.

D. Refrigerant Loss

Kooltronic Air Conditioners are subjected to a series of tests to detect refrigerant leaks, during and
after manufacture. It is possible that shipping or other damage, or microscopic leaks over a long
period, may result in the need for replenishment of refrigerant charge.

When it has been verified

by a Certified EPA Technician that a refrigerant shortage does exist, the leak must be
repaired. Then the unit may be evacuated and recharged in the field by a Certified EPA
Technician only.

CAUTION

E. Relocation

If your Kooltronic Air Conditioner has to be moved to another location by truck, the following
precautions should be taken:

De-mount the air conditioner from the equipment, controller or enclosure.

Conform to the applicable provisions of PROCEDURE FOR PROPER PACKING AND
SHIPMENT OF KOOLTRONIC AIR CONDITIONERS in this manual under 

Section III.

"PRODUCT HANDLING".

Before opening the air conditioner, disconnect all power.

Refer to the data on the unit name plate which specifies the type of

refrigerant and the amount of charge in ounces.
