VIII. Maintenance

Kooltronic Water-Cooled Air Conditioners require no maintenance. Air-Cooled Air
Conditioners are designed to require only the routine cleaning of air filters to assure
unimpeded air flow through the condenser heat exchanger. It is not possible to
recommend specific filter cleaning intervals since the level and the nature of airborne
particulate matter differs widely with each installation. It is generally sufficient to remove
and wash the reusable aluminum mesh air filters when the outer surfaces of these filters
appear covered with a thin layer of dust or lint. Filter recoating adhesive is recommended.
Appropriate disposable filters are available from Kooltronic.

If filter service is neglected or delayed, the air conditioner will not perform at its design
capacity. The first indication of excessively clogged air filters is usually a gradual
increase of temperature within the equipment cabinet. If operation is continued under
these conditions, the compressor will be shut off by the thermal overload device. The
compressor will restart when its external temperature drops below the protector threshold
setting and the compressor will continue to cycle on and off. Continued operation under
these conditions will cause damage, shorten compressor life and void the warranty.

A. Filter Removal and Service

Kooltronic Air Conditioners feature an easily removable inlet filter to facilitate
necessary cleaning.

CAUTION

1) Lift the filter, using the attached tab, to clear the lower filter retainer. Pull filter

toward you and downward until the top of the filter clears the upper filter retainer.

2) After removal, the filters should be flushed under warm running water with

the clean side up, driving contaminants out the dirty side of the filter. If the
accumulated dirt is oily, washing in a detergent bath is recommended, followed
by a warm water rinse as above.

3) The filters may be sprayed with Kooltronic A-16 Filter Recoating Adhesive to

trap fine airborne contaminants, or they may simply be dried and reinstalled as
strainer type filters. Recoating is recommended for best results.

4) Reinstall the filter: (a) keeping the tab at the bottom, slide filter into the upper

retainer, (b) press filter against the unit and (c) slide down into lower retainer.

Do not operate the Air Conditioner for extended periods of time with the

filter removed. The condenser coil may become clogged with dust or

lint from the air entering the face. A clogged condenser coil is not

readily detected and will give the same reaction as a clogged filter. A

clean filter is the best protection.
