X. Maintenance
Kooltronic Guardian/GuardianX NEMA 4 or 4X 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 6 for part numbers.
If filter service is neglected or delayed, the filter fans will not perform at 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 Guardian/GuardianX NEMA 4 or 4X Series Indoor/Outdoor Filter Fans feature an easily removable
filter to facilitate necessary cleaning.
CAUTION
1) On the bottom of the unit, pull the filter retainer away from the cabinet and downward to remove filter and filter
retainer.
2) After removal, the filter 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.
3) Reinstall the filter and filter retainer, making sure that the retainer legs face toward the cabinet.
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.
