C. 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 

 

 
 

 
 
 
 

D.  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".

Refer to the data on the unit nameplate which specifies the type of 

refrigerant and the amount of charge in ounces. 

Before opening the Air Conditioner, disconnect all power.

.
