VIII. Maintenance

Kooltronic Air-Cooled Air Conditioners require routine cleaning of the condenser coil (if necessary) and the
air filters to assure unimpeded airflow through the condenser heat exchanger. It is not possible to recommend
specific condenser coil or filter cleaning intervals, since the level and the nature of airborne particulate matter
differs widely with each installation. It is generally sufficient to clean the condenser coil and/or the aluminum
mesh filter when the outer surfaces appear covered with a thin layer of dust, lint or other foreign matter. The
condenser coil can be blown out with air, or washed, depending on the foreign matter involved. Disconnect
power and remove air conditioner from cabinet before using liquids to clean the unit. (see below - 

Filter and

condenser coil service

). The aluminum mesh filter can be washed with warm water. Appropriate

disposable replacement filters are available from Kooltronic.

If routine condenser coil or filter service is neglected or delayed, the air conditioner will not perform at its
design capacity. The first indication of an excessively clogged condenser coil or air filter 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 and condenser coil service

Kooltronic RT Top Mount Air Conditioners feature an easily removable inlet filter to facilitate
necessary cleaning. To access the filter, loosen the torx screws and remove the front grille. Push the
filter upward and pull the bottom edge forward to remove. After removal, the filters should be flushed
under warm running water with clean side up. If the accumulated dirt is oily, washing in a detergent
bath is recommended, followed by a warm water wash as above. To reinstall the filter, insert the filter
into the filter holder and push the filter back into position. Reinstall the front grille using the torx
screws.

The condenser coil must be cleaned using pressurized air. If liquid cleaning solutions are used, it is
necessary that the air conditioner be removed from the cabinet to avoid liquids draining into the
electronics. Disconnect power before performing this type of operation. 

CAUTION

B. Blowers

The design life of the blowers employed in all Kooltronic Air Conditioners is substantially in excess of
20,000 hours. All Kooltronic condenser and evaporator blowers are equipped with UL/CSA
permanently-lubricated precision ball-bearing motors, with automatic-reset thermal overload protectors.
If field replacement of a blower motor is necessary, most blower assemblies, including the mounting
plate, are readily removable. Each of the blower mounting plates is held to the air conditioner cabinet
structure by screws and nuts. For installation of the replacement blower, electrical connections may
be broken at the terminal block, or power leads may be cut and appropriately spliced together. 

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.
