grille in the wall or ceiling. Check the filter monthly and
clean or replace it as needed.
Disposable filters should be replaced with a filter of the
same type and size.
Check the indoor unit drain line for obstructions monthly
during the cooling season.
The indoor evaporator coil is equipped with a drain pan
to collect condensate formed as your system removes
humidity from the inside air. Have your installer show you
the location of the drain line and how to check for
obstructions. (This would also apply to an auxiliary drain,
if installed.)
Check the area around the outdoor unit monthly and
remove any obstructions that may restrict airflow to the
outdoor unit. This would include grass clippings, leaves,
or papers that may have settled around the unit.
Trim shrubbery away from the unit and periodically check
for debris which collects around the unit.
During the winter months, keep the snow level below the
louvered panels.
The filter and all access panels must be in place

IMPORTANT !
Sprinklers and soaker hoses should not be installed
where they could cause prolonged exposure to the
outdoor unit by treated water. Prolonged exposure
of the unit to treated water (i.e., sprinkler systems,
soakers, waste water, etc.) will corrode the surface
of steel and aluminum parts, diminish performance
and affect longevity of the unit.
