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:

I

De-mount Air Conditioner from equipment, controller or enclosure.

I

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

Section III.

"PRODUCT HANDLING".

refrigerant and the amount of charge in ounces. 

.

IX. Trouble-Shooting

Each Kooltronic Air Conditioner is engineered for performance and built for reliability. They are designed to
require only routine maintenance. If your air conditioner should require warranty service, please
contact Kooltronic. If you require service out of warranty, we have compiled a trouble-shooting chart
to assist your service personnel. If additional assistance is required contact Kooltronic at (609) 466-3400
