MAINTENANCE

INDOOR COIL

Do not allow dirt to accumulate on the indoor coil or other
parts of the supply/return air circuit. Clean as often as neces-
sary to assure good system performance. Use a brush vac-
uum cleaner attachment or other suitable means.
If the coil becomes extremely dirty, it may be necessary to
use an industrial grade detergent and a hose to clean the
finned surfaces. This is recommended to prevent any loss in
capacity and efficiency.

FILTERS

The filters must be replaced as often as necessary to assure
good air flow and filtering action. Clean filters will prevent
any loss in capacity and efficiency.
