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:
■
De-mount Air Conditioner from 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".
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.
