VIII. Maintenance

Kooltronic Air-Cooled Air Conditioners require routine cleaning of the condenser coil (if necessary) and the air
filters (if they are supplied) 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 washed or blown out with air, depending on the foreign matter involved (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

If an optional filter is installed on externally mounted air conditioners (filter should not be used for internal
mounted air conditioners), the rear panel must be removed in order to clean the filters. 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.

If an optional filter is not used for an externally and/or internally mounted air conditioner, the exposed
condenser coil must be cleaned by pressurized air or pressurized cleaning solution. Dirty liquid will be
removed through the condenser coil drain pan.

B. Blowers

The design life of the blowers used in all Kooltronic Air Conditioners is substantially in excess of 20,000
hours. All Kooltronic condenser and evaporator blowers are equipped with automatic-reset thermal
overload protectors.

CAUTION

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.

C. Compressor

All Kooltronic compressors are approved by UL and CSA, and require no maintenance. They are
hermetically sealed and charged at the factory, and equipped with automatic-reset thermal overload
protectors.

If the compressor fails, it is strongly recommended that the air conditioner be returned to Kooltronic for
service.

Before opening the air conditioner, disconnect all power.
