B. Blowers

The design life of the blowers employed in all Kooltronic Air Conditioners is 
substantially in excess of 20,000 hours. All Kooltronic condenser and evaporator 
blowers are equipped with UL/CSA permanently-lubricated precision ball-bearing 
motors, with automatic-reset thermal overload protectors. 

CAUTION

 

If field replacement of a blower motor is necessary, most blower assemblies, 
including 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 or the hot gas bypass valve 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 Air Conditioner from 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 nameplate which specifies the type of 

refrigerant and the amount of charge in ounces.
