If your system is an add-on type, (installed in conjunction with a stan-
dard furnace) inspect your furnace blower motor and care for it in the
same way.
FILTER CARE
Inspect the air filter(s) at least once a month. If they are dirty, wash
reusable filters with a mild detergent per manufacturer’s recommenda-
tions. Replace disposable filters with new filters.
Install the clean filters with “air flow” arrow in the same direction as the
air flow in your duct. Filters should be clean to assure maximum effi-
ciency and adequate air circulation. Drapes, furniture or other obstruc-
tions blocking your supply and return air grilles will also decrease
efficiency.
OUTDOOR UNIT FINISH
If you wish to maintain the finish of the outdoor unit, it can be polished
with car wax. It is recommended the unit be cleaned with soap and
water prior to waxing.
CLEARANCES
The minimum clearances shown below must be maintained should any
patio or yard improvements be done around the outdoor unit.
