PERFORMING ROUTINE
MAINTENANCE
With the proper maintenance and care, your heat pump will
operate economically and dependably. Maintenance can be
accomplished easily by referring to the l\_llowing directions.
However, bet\_re performing maintenance, consider these
important safety precautions:
Disconnect all electrical power to the indoor air han-
dler or furnace before removing access panels to per-
form any maintenance. Disconnect power to both the
indoor and outdoor units. Note: There may be more
than one electrical disconnect switch. Electrical
shock can cause personal injury or death.
Although special care has been taken to minimize
sharp edges in the construction of your unit, be ex-
tremely careful when handling parts or reaching into
the unit. Failure to follow this caution could result in
minor personal injury or product and property
damage.
CHECKTHE AIR FILTER
A dirty air filter will cause excessive strain on the compressor
and blower motor. This can cause the components to over-heat
and automatically shut down. In the worst case, the compo-
nents will fail and need to be replaced. To avoid inefficient or
failed operation of your unit, CHECK THE FILTER(S)
EVERY 3 TO 4 WEEKS. Replace filter(s) when necessary, or
clean the filter(s) if you have the reusable type.
Disposable filters should be replaced by similal: new filters of
the same dimensions.
Reusable, permanent filters should be washed in a solution of
cold water and mild detergent, then rinsed and thoroughly
dried. THE FILTER MUST BE COMPLETELY DRY
BEFORE BEING REINSTALLED. To avoid prolonged shut-
down of your unit while a filter is drying, you should have an
extra filter on hand. This allows you to rotate between the 2
with minimal downtime for your coml\_rt system. Extra filters
may be purchased from your dealer.
There are no filters in the outdoor unit of a split system. If your
indoor unit is a gas or oil furnace, refer to your furnace User's
Manual tier filter location and procedures for replacement or
cleaning.
If your system includes an indoor thn coil unit, the filter may be
located in the unit where it connects with the return-air duct or
plenum. (See Fig. 1.)Remove the filter cover plate by sliding
latches toward center of plate. Lift filter to clear lower flange. Fil-
ter is spring-loaded and will "pop out." Reinstall filter, being cer-
tain to secure filter behind lower flange. When reinstalling cover
plate, secure plate behind upper flange then slide tabs outward.
The indoor fan coil unit may be located in the attic. In this
instance the filter may be located behind the return air grille.
Access the filter by removing the return air grille.
If your system includes a high efficiency or electronic air
cleaner, refer to air cleaner User's Manual t\_r proper filter
cleaning or replacement.
INDOOR COIL
If the split-system coil hits only been operated with a clean
filter in place, it should require minimal cleaning.
If coil cleaning is required, call your dealer ti_r service. It may
be necessary to clean the coil with a detergent solution and
rinse it with water. This could require the removal of the coil.
You should not attempt this yourself.
OUTDOOR COIL
IS"grass clippings, leaves, shrubbery, and debris are kept away
from the outdoor unit, minimal care should be sufficient to
keep the system functioning properly. For proper drainage,
debris must be removed periodically from the base pan. How-
ever, if the outdoor coil becomes dirty, use a vacuum cleaner
or shop vac with soft blush attachment to clean the exterior
surface. Vacuum coil surface using an up and down motion. Be
carefnl not to bend or damage fins.
If dirt is deep in the coil, contact your dealer t\_rservice. The
outdoor fan motor may have to be disconnected and the top
panel removed to gain access to the coil t\_rthorough cleaning.
Do not attempt this yourself.
OUTDOOR COILmSEA COAST
If your unit is located near the ocean, special maintenance is
required. Ocean mist/breeze CalTiessalt, which is conosive to
most metals. Although your new unit is made out of galvanized
metal and is protected by top-grade paint, you should take the
precaution of additional maintenance which consists of period-
ically washing the unit. By washing all exposed surfaces and
coil, you will be adding additional life to your unit. Please
consult your installing contractor for proper intelwals/proce-
dures t\_r your geographic area or selwice contact.
