Proper Maintenance – Air Handlers
Don’t waste money heating and cooling
To prevent injury or death, or property damage, read and follow all
instructions and warnings, including labels shipped with or attached
to unit before operating your new air conditioning system.
Improper installation, adjustment, alteration, service maintenance,
or use can cause explosion, fire, electrical shock, or other conditions
which may cause personal injury or property damage. Consult a
qualified installer or service agency for information or assistance.
The qualified installer or agency must use factory-authorized kits or
accessories when modifying this product.
Disconnect all electric power to the indoor air handler or furnace
before removing access panels to perform any maintenance.
Disconnect power to both the indoor and outdoor units.
A clean filter saves money.
Help ensure top efficiency by cleaning the filter regularly.
When the unit circulates and filters the air in your home, dust
and dirt particles collect on the filter located in your indoor unit.
Excessive buildup forces the system to run longer to maintain your
set temperature. And you end up paying for it.
Although special care has been taken to minimize sharp edges
in the construction of the unit, be extremely careful when
handling parts or reaching into the unit.
Clean or replace your filter at least once a month or
twice a month when the system is running more.
If you have a semi-permanent
filter, you can take the filter out of
the frame and vacuum it. Where

disposable filters are used, they
must be replaced every month
with the same size as originally
supplied.
Both methods are quick and easy
and guaranteed to cut the energy
used by your system. When replacing your air handler filters,
always use the same size and type that was originally supplied.
Filters are available from your dealer.
when you don’t need to.
When you’re going to be away from home for a few days –
or when outdoor temperatures are moderate – don’t let your
system run unnecessarily. Lower the thermostat to 55°F in the
winter. And raise it to 85°F in summer. Then when you return –
or when temperatures dictate – you can reset the system and it
will immediately begin making your home comfortable again.
Continuous fan mode during cooling operation may not be
appropriate in humid climates. If the indoor air exceeds 60%
relative humidity or simply feels uncomfortably humid, it is
recommended that the fan only be used in the AUTO mode.
If heating system is not operational during the cold weather
months, provisions must be taken to prevent freeze-up of
all water pipes and water receptacles. This is very important
during times of vacancy.
Never stop the system by shutting off the main power.
If the main power is ever disconnected for more than three
hours, turn off the thermostat. Then wait for at least three more
hours after the power has been restored before turning the
thermostat back on. Failure to follow this procedure could result
in damage to your system.
How to remove the filter from your Air Handler.
Ask your dealer where the filter is located when your system
is installed. It may be behind the bottom panel of your indoor
unit. Or it may be at the top, bottom, or either side. Or there
may be two filters.
In any case, removing a filter is easy. Just make sure you insert
the clean filter with the arrows on it pointing in the direction
of the airflow.
Your installing dealer is your best source of filter and
maintenance information.
Locate access door marked
"FILTER" and lift up the open
side of the levers.
Cut operating costs by keeping snow, ice and debris clear
of your outdoor heat pump unit.
NOTE: Condensation may occur on the surface of the air
handler when installed in an unconditioned location.
Efficient operation of your outdoor unit requires the free flow
of air over the coils. Anything that blocks this flow forces the
unit to work harder to do its job. At no time should anything be

stacked against the side of the outdoor unit or draped over it.
Keeping it clear of debris helps it work at peak efficiency, and
that helps hold down operating costs.

3. Improperly adjusted thermostat
Unusual Noise Call your local servicer

2. Reset circuit breaker, or replace burned‑out fuses
3. Check setting, adjust thermostat
Just set the temperature you want.
Whenever your house is to be vacant, arrange to have
someone inspect your house for proper temperature. This
is very important in below freezing weather. If for any reason
your unit should fail to operate, damage could result, such
as frozen water pipes.
NOTE: Improperly sized vents can cause the formation of
condensate, combustion gas leakage and spillage, and an
inoperable furnace.
This unit is not a household appliance. It is a complex
self-contained system that requires professional maintenance
and repair. That’s why attempts at do it yourself repairs on an
in-warranty unit may void the remainder of your warranty. Other
than performing the simple maintenance recommended in this
manual, you should not attempt to make any adjustments to
your system.
NOTE: The blower motor bearings are factory lubricated and
under normal operating conditions usually do not require
servicing. Your local servicer can advise you if oiling is required.
Your dealer should be able to take care of any questions or
problems you may have.
Set temperatures by using the indicators on the thermostat*
control. After that, your comfort control center (thermostat) will
maintain a constant indoor temperature, regardless of changes
in outdoor temperatures. Read your thermostat manual for
directions on setting the temperatures.
Save energy with an electronic programmable thermostat.
With an electronic programmable thermostat* energy savings is
easy. Just program the thermostat for the temperatures you are
most comfortable with and it will automatically change settings
up to four times a day. Special weekend and vacation schedules
are also easily programmed for comfort and savings. Read your
thermostat manual for programming instructions. If you want
the optimum balance between comfort and the cost of running
your system, we recommend keeping the temperature settings
at 68°F for heating and 78°F for cooling.
Save energy by letting the thermostat do its job. Once you
set the thermostat, keep subsequent adjustments to a minimum.
Adjust it only when a new program is needed.
*Optional accessory
Keep your unit looking like new for years.
Clean the enamel finish of your unit with ordinary soap and water.
For stubborn grease spots, use a household detergent. Lacquer
thinner or other synthetic solvents may damage the finish.
