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

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".

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

refrigerant and the amount of charge in ounces.
