SYSTEM MAINTENANCE
CAUTION:
Verify all electrical power to the unit is
disconnected and the gas is shut off before
performing the following recommended
maintenance.
Proper maintenance is most important to achieve the best
performance from the appliance and should be performed by
a qualified service technician at least once a year. Follow the
maintenance schedule and the instructions below for years of
safe, trouble free operation.
• Annually inspect the physical support of the unit to ensure
that it is physically sound without sagging, cracks, gaps, etc.,
around the base so as to provide a seal between the support
and the base.
• Annually inspect the return-air connection to ensure that it is
physically sound and is still sealed to the casing of the unit.
Also inspect the unit, ductwork, and vent system for signs of
physical deterioration.
• Do not operate the unit without all doors and covers in place.
Avoid operating the unit when windows and doors are open.
• Refer to the Maintenance Schedule below (Table 1) for
recommended maintenance information.
CAUTION:
DO NOT make contact with any of the internal
electrical components while cleaning the unit.
Regular Cleaning

coil. Check for and remove any obstructions such as twigs,
sticks, etc.
Be careful not to damage the aluminum fins
Air Filters
WARNING:
Never operate the unit without a filter in the return
air system. Dust and lint in the return air can
build up on the internal components, resulting
in loss of efficiency, equipment damage, and
possible fire risk.
This unit is not supplied with air filter(s) and has no means for
accommodating internal air filter(s). The installer is responsible
for installing a filtration system into the return air duct of this
system. The filter(s) of this system should be checked at monthly.
It is very important to replace or clean the filter(s) installed in
the return air duct of this system. A clogged filter could cause
airflow related problems and reduce the overall efficiency of your
unit. Depending upon which type of filter was installed with your
unit, clean (permanent) or replace (disposable) filter(s) of your
system at the beginning of every heating season, the beginning
of every cooling season, and when an accumulation of dust and
dirt are visible on the filter.
IMPORTANT NOTE:
Replace disposable filter(s) installed in your system only with
the same size dimensional filters that are being replaced. Clean
permanent filter(s) as described by the manufacturer.
