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.
