IMPORTANT NOTE: Never operate unit without a filter installed
as dust and lint will build up on internal parts resulting in loss of
efficiency, equipment damage and possible fire.
A return air filter is not supplied with this unit; however, there
must be a means of filtering the return air. An indoor air filter
must be used with your comfort system. A properly maintained
filter will keep the indoor coil of your comfort system clean. A
dirty coil could cause poor operation and/or severe equipment
damage.
The installer of your unit can tell you where your filter(s) are and how to clean or replace them.
Check your return filter(s) at least once every two months. When they are dirty, replace or clean as required. Disposable type
filters should be replaced. Reusable type filters may be cleaned.
NOTE: Reusable type filters should be washed with warm water, dried completely and sprayed with an adhesive according to
the manufacturers recommendations.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-
electronic types. These filters can do a better job of catching small airborne particles.
Improper filter maintenance is the most common cause of inadequate heating or cooling performance. Filters should be cleaned
(permanent) or replaced (disposable) every two months or as required. When replacing a filter, it must be replaced with a filter of
the same type and size and always make certain the air flow arrows on the filter point in the proper direction.

Your package unit should be inspected by a qualified installer, or service agency at least twice every year. This check should be
performed before the heating and cooling seasons begin. This will ensure that adequate combustion air is being drawn and the vent
system is working properly. Particular attention should be paid to the following items. Repair as necessary.
•
Check physical support of the unit. Ensure it is sound without any sagging, cracks, or gaps, around the base.
•
Check for obvious signs of deterioration of the unit.
•
Flue Hood and Combustion Air Inlet. Check for blockage (wasp nest, etc.) and corrosion.

The outdoor coil should be inspected annually. It is important to keep the outdoor coil clean. Dirt, leaves, or debris could restrict
the airflow. If cleaning of the outdoor coil becomes necessary, hire a qualified servicer. Inexperienced people could easily punc-
ture the tubing in the coil.
