VIII. Maintenance
The RP55 is 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,
(Part No. A-16)
, available from
Kooltronic, is recommended. Replacement aluminum mesh filters are also 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) Loosen the screw on the bottom of the filter holder.
2) Push the filter holder forward and move it down.
3) Remove the filter from the filter holder.
4) 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.
5) 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.
6) Reinstall the filter: Insert the filter inside the filter holder, push the filter holder forward, move it up
into place and replace the screw on the bottom of the filter holder.
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.
