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 qualified professional that a refrigerant shortage does exist, the leak must be 
repaired. Then the unit may be evacuated and recharged in the field by qualified service 
people 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.
