Your Self Contained Packaged Air Conditioner and Heat Pump
should operate for many years without excessive service calls
if the unit is installed properly. However it is recommended
that the homeowner inspect the unit before a seasonal start
up. The coils should be free of debris so adequate airflow is
achieved. The return and supply registers should be free of
any obstructions. The filters should be cleaned or replaced.
These few steps will help to keep the product up time to a
maximum. The Service section that follows should help in
identifying problems if the unit does not operate properly.

BUILD UP ON INTERNAL PARTS, NEVER OPERATE UNIT WITHOUT AN AIR
FILTER INSTALLED IN THE RETURN AIR SYSTEM.
Every application may require a different frequency of replace-
ment of dirty filters. Filters must be replaced at least every
three (3) months during operating seasons.
Dirty filters are the most common cause of inadequate heat-
ing or cooling performance. Filter inspection should be made
at least every two months; more often if necessary because
of local conditions and usage.
Dirty throwaway filters should be discarded and replaced with
a new, clean filter.
Disposable return air filters are supplied with this unit. See
the unit Specification Sheet or Technical Manual for the cor-
rect size and part number. To remove the filters, remove the
filter access panel on return side of the unit.

Use a fine grade automotive wax on the cabinet finish to
maintain the finish's original high luster. This is especially
important in installations with extended periods of direct sun-
light.
