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:
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.
