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. 
 
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.
