The hotter the outside temperature, the greater the load on your sys-
tem. Therefore do not be alarmed when your system continues to run
after the sun has set on a hot day. Heat is stored in your outside walls
and attic during the day and will continue to flow into your home for sev-
eral hours after sunset.
Use your kitchen exhaust fan when cooking. One surface burner on
“HIGH” requires one ton (12,000 BTUs) of cooling. Turn on your bath-
room exhaust fan while showering to remove humidity. However,
exhaust fans should not be run excessively. It would decrease effi-
ciency by removing conditioned air.
You can help your system in the summer by closing drapes or blinds
and by lowering awnings on windows that get direct sunlight.
SECTION IV: CARE OF SYSTEM
A periodic inspection, cleaning, lubrication, and adjustment of your heat
pump is available from your dealer. Be sure to ask him about this ser-
vice.
It is recommended that your heating and air conditioning system is
inspected on a yearly basis by a licensed and qualified service provider.
The service technician should clean coils, inspect and tighten all electri-
cal connections, clean drain lines, and check for proper system opera-
tion.
For those who prefer to do-it-yourself, follow the instructions below to
care for your system.
MOTOR LUBRICATION
The motors in these Air Handlers are permanently lubricated, and do
not require periodic oiling.
PERIODIC INSPECTION
Every time the filters are changed, the following items should be visu-
ally inspected:
• Check unit exterior to be sure it is in good condition and that there
are no obvious signs of deterioration.
• Check the drain lines to make sure there are no cracks, leaks or
blockages.
• Check the area around the unit and all registers and grilles – to
maintain good air flow.
Periodic inspection by a qualified service technician is highly recom-
mended.
Cleaning & maintenance of the Air Handler interior and its components
must only be done by a qualified service professional.
For more information, or if you have questions about the operation of
your Air Handler, Or if you suspect your unit is malfunctioning or in need
of service or repair
• Call a certified dealer or servicing contractor to check and/or
clean your Air Handler.
AIR FILTERS
Air filters maybe internally or externally mounted. Dirty filters greatly
restrict the flow of air and may cause damage to the moving parts.
Some pleated filters may be too restrictive and should not be used. If
the filters become clogged the Electric Heaters and blower motor could
overheat resulting in a potentially dangerous situation. The filters
should be checked every month. On new construction, check the filters
every week for the first four weeks and every three weeks after that,
especially if the indoor fan is running continuously. When replacing the
filter(s) you must use filters that are the same size as those recom-
mended in Table 1. Never operate your Air Handler without a suitable
air filter.
Filter Care
Inspect the air filter every month. If dirty, wash reusable filters with
water. Replace disposable filters with new filters. Filters should be clean
to assure maximum efficiency and adequate air circulation. Drapes, fur-
niture or other obstructions blocking your supply and return air grilles
will also decrease efficiency.
An air filter was supplied by your dealer with your new Air Handler. A 1”
filter rack compartment was built-in on your new Air Handler and may
use either a 1” disposable filter or a permanent washable filter media
per Table 1.
Removing Internally Mounted Air Filters
This Air Handler may have a filter located on bottom of the unit behind
the filter access panel.
1. Remove filter access panel by removing screws from each side of
the filter access panel.
2. Install the clean filter with “air flow” arrow in the same direction as
the air flow in your duct. If air flow direction is indicated on the filter,
refer to Figure 1.
3. Replace the panel, and reinstall screws to secure the panel.
IMPORTANT
The owner/user should not attempt to disassemble the equipment nor
perform periodic maintenance unless they are experienced and quali-
fied to do so.
WARNING
Electric Shock and Moving Parts Hazards are present behind the
Blower & Coil access panels. Risk of Personal Injury and/or Fire or
Electric Shock, potentially causing property damage, personal injury,
and/or loss of life. The only owner serviceable part is the filter behind
the filter access panel
