Carrier WEATHERMASTER 2000 - Manual (Page 5)

If your system includes an indoor fan coil unit, the filter is
located in the unit where it connects with the retum-air duct
or plenum. See Fig. 4. Remove the two black thumbscrews
(or, plastic pull rings on modular fan coil), then puU out the
rack and filter. The clean filter must be reinstalled with the
cross-hatched side facing the blower. With the clean filter in
place, secure the spring tensioner, slide the tray into the
unit, then secure the thumbscrews.
INDOOR COIL
If the spUt-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 con 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 coU. 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 corrosive
to most metals. Although your new unit is made out of gal­
vanized metal and is protected by top grade paint, you
should take the precaution of additional maintenance. This
additional maintenance consists of periodic washing of 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 interveds/procedures for
your geographic area or service contact.
UNIT SUPPORT
Your split-system outdoor unit should be maintained at 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 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. Ver­
ify 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 tem­
perature 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 stUl fails to operate, contact your
servicing dealer for troubleshooting and repairs. Specify
your apparent problem, and state the model and serial num­
bers of your equipment. (You should have them recorded on
Pages 5 & 6 of this booklet.) With this information, your
dealer may be able to offer helpful suggestions over the
phone or save valuable time through knowledgeable prepa­
ration 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 (prefer­
able twice each year, but at least
once every year) should
include the following:
• Routine inspection of air filter(s). Replacement or clean­
ing as required.
• Inspection and cleaning of the blower wheel, housing,
and motor as required.
• Inspection and, if required, cleaning of indoor and out­
door 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 aU electrical wiring and connections.
• A check for secure physical connections of individual
corhponents 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.
