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 airflow 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 of 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 Coating Adhesive

to trap fine airborne

contaminates, or it may simply be dried and reinstalled. 

Recoating is recommended for the 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, as
the condenser coil may become clogged with dust or lint from the air entering the face. A

unit with a clogged condenser coil will have the same reaction as one with a clogged filter.

A clean filter is the best protection.
