HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a bi-annual maintenance checkup be performed
by a qualified service agency before the heating and cooling seasons begin.

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 inad-
equate heating or cooling performance. Filters should be cleaned
(permanent) or replaced (disposable) every two months or as re-
quired. 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.

• Return Air Connection. Check for physical soundness
and ensure that the connection is firmly sealed to the
package unit casing.
• Heat exchanger. Check for corrosion and/or obstructions
within the heat exchanger passageways.
• Burners. Check for proper ignition, burner flame, and
flame sense.
• Wiring. Check wires for damage. Check electrical
connections for tightness and/or corrosion.
• Filters. Check that filters are clean and in the proper
placement in the unit or duct system.
• Louvers. Inspect air inlet louvers inside the heat
exchanger compartments. Ensure the area is clean and
free of dirt and debris.
Clean Outside Coil (Qualified Servicer Only)
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 puncture the
tubing in the coil.
