your Heat Pump system's ability to operate economically and
dependably. Always remember the following safety precautions:
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Disconnect all electrical power to the indoor air handler or
furnace before removing access panels to perform any
maintenance. Disconnect power to both the indoor and
outdoor units (see Fig. 1.)
NOTE: There may be more than one electrical disconnect
switch.
PERSONAL INJURY AND/OR PRODUCT AND
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in personal injury or

INDOOR UNIT (Furnace or Fan Coil)
(Also refer to the furnace or fan coil Owner's Manual)
• Check the Air Filter Monthly
There are no filters on your outdoor unit. However, a dirty air
filter on the indoor unit can cause overheating, automatic system
shutdown, and in extreme cases, component failure.
CHECK THE FILTER(S) MONTHLY AND CLEAN OR
REPLACE AS NEEDED. For details on how to check, clean or
replace your filter(s), refer to your furnace or fan coil owner's
manual. OR, if you have an electronic air cleaner or a larger,
"boxed" air filter, refer to the owners manual supplied with those
products.
• Coil Cleaning
Your indoor coil is located in a sealed cabinet on your indoor unit
and will require minimal cleaning with routine filter maintenance.
Longer operating cycles and reduced energy efficiency may
indicate the need for a coil cleaning by your Carrier dealer.
OUTDOOR UNIT
• Coil Cleaning
The most visible part of the outdoor unit is the large "coil"
wrapped around the inner components of the Heat Pump. If grass
clippings, leaves, shrubbery, and debris are kept away from the
coil. minimal care is needed. If the coil becomes dirty, clean the
coil surface with a vacuum cleaner using a soft brush attachment.
Use an up and down motion being careful not to bend or damage
the delicate, aluminum coil fins. If dirt is deep in the coil, contact
your dealer for service.
• Base Pan Drainage
Periodically check for and remove debris that has settled around
the base of your outdoor unit. This will ensure proper drainage
of the base pan and eliminate standing water inside the outdoor
umt.
• Level Installation
Your Carrier dealer will install the outdoor unit in a level position.
If the support base settles or shifts and the unit is no longer level,
be sure to re-level it promptly to assure proper drainage. If you
notice water or ice collecting beneath the unit, arrange for it to be
drained away from the unit.
SEA COAST COIL MAINTENANCE
Coastal locations often require additional maintenance of the
outdoor unit due to highly corrosive airborne ocean salt.
Although your new Carrier system is made of galvanized metal
and is protected by top-grade paint, take the additional
precaution of periodically washing all exposed surfaces and the
outdoor coil approximately every 3 months. Consult your
installing Carrier dealer for proper cleaning intervals and
procedures for your geographic area or ask about a service
contract for regularly scheduled professional cleaning and
inspections.
