Proper Maintenance – Air Handlers
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.
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.
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.
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.
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.
Don’t waste money heating and cooling
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.
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.
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.
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.
Locate access door marked
"FILTER" and lift up the open
side of the levers.
Slide dirty filter out, replace with a
new filter making sure the arrows
printed on it are pointing in the
direction of airflow.
Hold the "FILTER" door firmly in
place and snap the levers down
(closed).
Your filter may
or may not be
framed.
