WE STRONGLY RECOMMEND A BI-ANNUAL MAINTENANCE CHECKUP BE PERFORMED BY A QUALIFIED SERVICE AGENCY BEFORE
THE HEATING AND COOLING SEASONS BEGIN.
WARNING
Never operate unit without a lter
installed as dust and lint will build up on internal parts
resulting in loss of eciency, equipment damage and
possible re.
A return air lter is not supplied with this unit; however,
there must be a means of ltering the return air. An indoor
air lter must be used with your comfort system. A properly
maintained lter 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 lter(s) are and how to clean or replace
them.
Check your return lter(s) at least once every two months.
When they are dirty, replace or clean as required.
Disposable type lters should be replaced. Reusable
type lters may be cleaned.Reusable type lters
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 eciency
lters. High eciency lters are available in both electronic
and non-electronic types. These lters can do a better job
of catching small airborne particles.
Improper lter 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 lter, it must be
replaced with a lter of the same type and size and always
make certain the air ow arrows on the lter point in the
proper direction.
The bearings on the air circulating blower motor and
condenser motor are permanently lubricated and require
no further lubrica-tion.
The compressor motor is hermetically sealed and does not
re-quire additional oiling.
This unit is equipped with an aluminum tube evaporator
coil. The safest way to clean the evaporator coil is to simply
ush the coil with water. This cleaning practice remains as
the recommended cleaning method for both copper tube
and aluminum tube resi-dential cooling coils.
An alternate cleaning method is to use one of the products
listed in the technical publication TP-109 (shipped in the
literature bag with the unit) to clean the coils. The cleaners
listed are the only agents deemed safe and approved
for use to clean round tube aluminum coils. TP-109 is
available on the web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of any
chemical cleaners.
Your package unit should be inspected by a qualied
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 the system is
performing properly and safely. Repair as necessary.

without any sagging, cracks, or gaps, around the
base.
• Check for obvious signs of deterioration of the unit.
• Check both condenser and evaporator coil to make
sure each are clean.
• Return Air Connection. Check for physical soundness
and ensure that the connection is rmly sealed to the
package unit casing.
• Wiring. Check wires for damage. Check electrical
connections for tightness and/or corrosion.
• Filters. Check that lters 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.
• Check the thermostat to conrm that it is properly set.

that it is closed.
• Check the electrical panel for tripped circuit breakers
or failed fuses . Reset the circuit breakers or replace
fuses as necessary.
