X. Maintenance

Kooltronic Advantage Sentry Series Indoor/Outdoor Filter Fans require no maintenance. These Filter Fans are
designed to require only the routine cleaning of air filters to assure unimpeded airflow through the unit. It is not possible
to recommend specific cleaning intervals, since the level and nature of airborne particulate matter differs widely with
each installation. It is generally sufficient to remove and wash the reuseable aluminum mesh air filters when the outer
surfaces of these filters appear covered with a thin layer of dust or lint. Filter coating adhesive, available from
Kooltronic, is recommended (Part number A-16 - 10 oz. container). Replacement filters are also available from
Kooltronic. See page 7 for part numbers.

If filter service is neglected or delayed, the filter fans will not perform at there design capacity. The first indication of an
excessively clogged filter is usually a gradual increase of temperature within the equipment cabinet. 

Filter removal and service

Kooltronic Advantage Sentry Series Indoor/Outdoor Filter Fans feature an easily removable filter to facilitate
necessary cleaning.

CAUTION

1) Remove the Torx tamper resistant screw at the bottom of the unit. Remove the cover to expose the filter.

2) Pull the filter downward until the top of the filter clears the upper filter retainer. Tilt the filter upward to remove

filter and/or filter retainer.

3) 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.

4) The aluminum mesh 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. 

5) Reinstall the filter and/or filter retainer.

6) Reinstall the cover with tamper resistant screw. 

Do not operate the filter fan for extended periods of time with the filter removed. Operation with

the filter in place is necessary for the fan to maintain its NEMA rating.
