cover plate by sliding latches toward
center of plate. Lift filter to clear lower
flange. Filter is spring-loaded and will
"pop out". Reinstall filter, being certain
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 application, the filter could
be located behind the return air grille.
Access the filter by removing 2 screws
from return air grille.
ELECTRONIC AIR CLEANER
If your system contains an Electronic Air
Cleaner consult the User's Manual for
specific care of that product.
INDOOR COIL
If the indoor 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. However,
if the outdoor coil becomes dirty, use a
vacuum cleaner with soft brush attach-
ment to clean the exterior surface. Vacuum
coil surface using an up and down motion.
Be careful not to bend or damage coil fins.
If dirt is deep in the coil, contact your deal-
er for service. The outdoor fan motor may
have to be disconnected and the top panel
removed to gain access to the coil for thor-
ough cleaning. Do not attempt this
yourself.
OUTDOOR COIL—
SEA COAST
If your unit is located near the ocean, spe-
cial maintenance is required. Ocean mist/
breeze carries salt, which is corrosive to
most metals. Although your new unit is
made of galvanized metal and is protected
by top-grade paint, you should take the
precaution of additional maintenance
which consists of periodically washing the
unit. By washing all exposed surfaces and
coil approximately every 3 months, you
will be adding additional life to your unit.
Consult your installing contractor for
proper intervals/procedures for your
geographic area or service contract.
UNIT SUPPORT
Your split-system outdoor unit should be
maintained in a level position. If its
support should shift or settle so that the
unit is no longer level, you should correct
the condition. Relevel it promptly to
assure that water drains out of the unit. If
you notice that water or ice collects
beneath the unit, arrange for it to be
drained away from the unit.
BEFORE YOU REQUEST
A "SERVICE CALL"
CHECK FOR THESE EASILY
SOLVED PROBLEMS:
• Check the indoor and outdoor dis-
connect switches. Verify that circuit
breakers are ON or that fuses have not
blown.
• Check for sufficient airflow. Check
the air filter(s) for any accumulations of
dirt. Check for blocked return-air or
supply-air registers. Be sure registers are
open and unobstructed.
• Check the settings on your indoor ther-
mostat. If you desire cooling, see that the
temperature control selector is set below
room temperature and the SYSTEM or
MODE control is set to COOL or AUTO.
If you require warmth, be sure the temper-
ature control selector is set above room
temperature and the SYSTEM or MODE
control is set to HEAT or AUTO. The
FAN switch should be set to ON for
continuous blower operation or AUTO
if you wish blower to function only while
the unit is operating.
If your comfort system still fails to
operate, contact your servicing dealer
for troubleshooting and repairs. Specify
your apparent problem, and state the
model and serial numbers of your equip-
ment. (You should have them recorded on
the last page of this booklet.) With this
information, your dealer may be able to
offer helpful suggestions over the phone or
save valuable time through knowledge-
able preparation for the service call.
REGULAR DEALER
MAINTENANCE
In addition to the routine maintenance
that you perform, your home comfort
5
system should be inspected regularly by
a properly trained service technician. The
inspection (preferably each year, but at
least every other year) should include the
following:
• Routine inspection of air filter(s).
Replacement or cleaning as required.
• Inspection and cleaning of the blower
wheel, housing, and motor.
• Inspection and, if required, cleaning of
indoor and outdoor coils.
• Inspection of the indoor coil drain pan,
plus the primary and secondary drain
lines. If supplied, the auxiliary drain pan
and line should be inspected at this time.
Service should include cleaning if
required.
• A check of all electrical wiring and
connections.
• A check for secure physical connec-
tions of individual components within
units.
• Operational check of the air condi-
tioning system to determine actual
working condition. Necessary repair
and/or adjustment should be performed
at this time.
Your servicing dealer may offer an
economical service contract that covers
seasonal inspections. Ask for further
details.
FOR THE RECORD
Record the model, product, and serial
numbers of your new equipment in
the spaces provided. This information,
