however, where it is necessary, such as when your heat pump
requires servicing.
If the electricity to your heat pump has been off for more than
30 minutes, switch your thermostat to EHEAT mode before
restarting your heat pump. Leave the system in EHEAT mode
for an amount of time equal to the power outage. It is not neces-
sary to exceed 12 hrs. If you cannot determine how long the
power has been off, leave the system in EHEAT mode for 8 hrs.
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 following directions.
However, before performing maintenance, consider these
important safety precautions:
CHECK THE AIR FILTER
A dirty air filter will cause excessive strain on the compressor
and blower motor. This can cause the components to overheat
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 similar, 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 comfort 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 for filter location and procedures for replacement or
cleaning.
If your system includes an indoor fan 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 for proper filter
cleaning or replacement.
INDOOR COIL
If the split-system coil has only been operated with a clean
filter in place, it should require minimal cleaning.
If coil cleaning is required, call your dealer for 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
If 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 brush attachment to clean the exterior
surface. Vacuum coil surface using an up and down motion. Be
careful not to bend or damage fins.
If dirt is deep in the coil, contact your dealer for service. The
outdoor fan motor may have to be disconnected and the top
panel removed to gain access to the coil for thorough cleaning.
Do not attempt this yourself.
OUTDOOR COIL—SEA COAST
If your unit is located near the ocean, special maintenance is
required. Ocean mist/breeze carries salt, which is corrosive 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
WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
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.
WARNING
CUT HAZARD
Failure to follow this warning could result in personal
injury.
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.
