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.
INDOOR COIL
If the split-system coil has only been operated with a clean
filter in place, it should require minimal cleaning. You may
use a vacuum cleaner and soft brush attachment to remove
any accumulation of dust from the top and underside of the
finned coil surface. However, perform this maintenance
only when the coil is completely dry.
If you cannot get the coil clean by this method, 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 suffi-
cient 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
brush or vacuum cleaner and soft brush attachment to clean
the exterior surface. 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 corro-
sive 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 periodically washing the unit. By washing all
exposed surfaces and coil, you will be adding additional life
to your unit. Consult your installing contractor for proper
intervals/procedures for your geographic area or service
contact.
UNIT SUPPORT
Your split-system outdoor unit should be maintained at a lev-
el 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 condensate drainage 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”
BEFORE YOU CALL FOR SERVICE, CHECK FOR
THESE EASILY SOLVED PROBLEMS:
• Check the indoor and outdoor disconnect 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 grilles. Be sure grilles are open and
unobstructed.
• Check the settings on your indoor thermostat. If you
desire cooling, see that the temperature control selector is
set below room temperature and the SYSTEM switch is on
the COOL or AUTO position. If you require warmth, be sure
the temperature control selector is set above room tempera-
ture and the SYSTEM switch is at HEAT or AUTO. The FAN
switch should be set at 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 ser-
vicing dealer for troubleshooting and repairs. Specify your
apparent problem, and state the model and serial numbers
of your equipment. With this information, your dealer may
be able to offer helpful suggestions over the phone or save
valuable time through knowledgeable preparation for the
service call.
REGULAR DEALER MAINTENANCE
In addition to the routine
maintenance that you perform,
your home comfort system
should be inspected regularly
by a properly trained service
technician. The inspection
(preferably twice each year,
but at least once every 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 as required.
• 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 connections of individual com-
ponents within units.
• Operational check of the heat pump system to determine
actual working condition. Necessary repair and/or adjust-
ment should be performed at this time.
Your servicing dealer may offer an economical service con-
tract 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, along
