B. Blowers
The design life of the blowers used in all Kooltronic Air Conditioners is substantially in excess of 20,000
hours. All Kooltronic condenser and evaporator blowers are equipped 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:
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".
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.
