Maintenance and Service
Air filter
Air filters must be purchased separately. Dirty filters
greatly restrict the flow of air and may cause damage
to the moving parts. If the filters become clogged the
Electric Heaters and blower motor could overheat
resulting in a potentially dangerous situation. The
filters should be replaced at least once a month. On
new construction, check the filters every week for the
first four weeks and every three weeks after that,
especially if the indoor fan is running continuously.
When replacing the Filter you must use filters that are
the same size as those recommended in Table 1.
Filter Care
Inspect the air filter every month. If dirty, wash
reusable filters with a mild detergent. Replace
disposable filters with new filters. Filters should be
clean to assure maximum efficiency and adequate
air circulation. Drapes, furniture or other obstructions
blocking your supply and return air grilles will also
decrease efficiency.
How to Clean your Filter
Permanent type, washable, High-velocity filters may
be cleaned with a vacuum cleaner or taken away
from the unit & washed with a garden hose. Be sure
to shake off excess water and allow filter to
completely dry before re-installing the filter.
CAUTION: Before performing any maintenance, turn off the main power to
the system.
