SAFETY CONSIDERATIONS
Recognize safety information. This is the safety-alert symbol
. When you see this symbol on the unit and in instructions
or manuals, be alert to the potential for personal injury.
!
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which
will result
in severe personal injury or death. WARNING signifies hazards
which
could result in personal injury or death. CAUTION is
used to identify unsafe practices which
would result in minor
personal injury or product and property damage. NOTE isused
to highlight suggestions which will result in enhanced installation,
reliability, or operation.
WARNING
Improper installation, adjustment, alteration, ser-
vice, maintenance, or use can cause explosion,
fire, electrical shock, or other conditions which
may cause serious injury, death or property dam-
age. Consult a qualified installer, service agency,
or your distributor or branch for information or as-
sistance. The qualified installer or agency must
use factory-authorized kits or accessories when
modifying this product.

which allows individual control over the temperatures of sep-
arate areas of your home or office.
• Your heat pump will remove humidity from your home or
office during the cooling season. After a few minutes of oper-
ation, you should be able to see water trickle from the conden-
sate drain. Check this occasionally to be sure the drain system
is not clogged. Of course, don’t expect to see much drainage if
you live in a very dry environment.
• During the heating cycle, air from your registers may seem
cooler than you might first expect. This is because your heat
pump delivers a constant flow of air at around 90°F to 105°F
instead of sudden bursts of hot air as with a conventional fur-
nace. This air may feel cool because it is slightly cooler than
your skin temperature. However, it is sufficiently warm to
keep you comfortable.
• Ice or frost will tend to form on the coil during the winter heat-
ing operation.Your heat pump is designed to automatically melt
the ice.When in this defrost cycle, it is normal for steam or fog to
rise from the outdoor unit. Do not be alarmed!
• Do not operate your unit in the cooling mode when outdoor
temperatures are below 55°F unless your unit was modified
for low-ambient operation.
• Do not operate your unit in the heating mode when outdoor
temperatures are above 66°F unless you set your thermostat
to emergency heat mode.
OPERATINGYOUR HEAT PUMP
The operation of your heat pump system is controlled by the
indoor thermostat.You simply adjust the thermostat and it
maintains the indoor temperature at the level you select. Most
thermostats for heat pump systems have 3 controls: a temper-
ature control selector, a FAN control, and a SYSTEM or
MODE control. Refer to your T-stat owner’s manual for more
information.

YOUR COMFORT SYSTEM
IdentifyingYour System
Take the time to familiarize yourself with your packaged heat
pump system.This knowledge will be of use in understanding
the basic operation of your new heat pump.
The unit has a rating plate affixed to it which provides neces-
saryinformationforspecificidentificationofaunit.Youshould
familiarize yourself with the product, model, and serial num-
bers listed on each rating plate. Record them for future refer-
ence on the last page of this booklet.
IMPORTANT FACTS
To betterprotectyourinvestmentand to eliminate unnecessary
service calls, familiarize yourself with the following facts:
• Your heat pump system should never be operated without a
clean air filter properly installed. Plan to inspect the filter peri-
odically. A clogged air filter will increase operating costs and
shorten the life of the unit.
• Supply-air and return-air registers should not be blocked.
Drapes, furniture, and toys are some of the items commonly
found obstructing registers. Restricted airflow lessens the
unit’s efficiency and life span.
• The outdoor unit must have unrestricted airflow. Do not cov-
er the unit, lean anything against it, or stand on it. Do not allow
grass clippings, leaves, or other debris to accumulate around
or on top of the unit. Maintain a 12-in. minimum clearance
between the outdoor unit and tall grass, vines, shrubs, etc.
• Your multipurpose indoor thermostat is the control center
for your heat pump system.You should familiarize yourself
with its proper operation.Attempting to control the system by
other means—for instance, switching the electrical supply
power ON and OFF—may cause damage to the unit. (See
Fig. 3.)
• During heating, increasing the thermostat setting more than
2º may cause the supplemental heaters to be turned on for a
short period of time to satisfy the thermostat. Needless use of
the supplementary heat reduces potential energy savings.
• You may find that you can maintain greater personal com-
fort by running the fan continuously. “Air pockets” can form
due to the structure of your home or office, placement of reg-
isters, etc.These air pockets may be too cool or warm for your
liking. Continuous fan operation minimizes any temperature
differences. Also, systems equipped with electronic or
mechanical air cleaners and/or humidifiers offer the added
benefits of having the air continuously cleaned year-round and
humidified during the winter season.
• A system equipped with a heat or energy recovery ventilator
offers the advantage of exhausting stale air from your home or
office and allowing fresh air in from the outdoors while mini-
mizing heat loss.
• Your system may also be equipped with a zoning system
WARNING
To prevent serious injury, death, or property dam-
age, read and follow all instructions and warnings,
including labels shipped with or attached to unit
before operating your new heat pump.

COOLING MODE
When operating in cooling mode, your heat pump will run in
cooling mode until the indoor temperature is lowered to the
level you have selected. On extremely hot days, your heat
pump will run for longer periods at a time and have shorter
“off” periods than on moderate days.
The following are typical conditions that add extra heat and/or
humidity to your home or office.Your heat pump will work
longer to keep your home or office comfortable under these
conditions:
• Entrance doors are frequently opened and closed
• Laundry appliances are being operated
• A shower is running
• Morethan theusualnumber of peopleare present inthehome or
office
• More than the normal number of electric lights are in use
• Drapes are open on the sunny side of the home or office
HEATING MODE
With the SYSTEM or MODE control of your indoor thermo-
statsettoHEAT,yourheatpumpwillrunin heating mode until
room temperature is raised to the level you have selected. Of
course, your heat pump will have to operate for longer periods
to maintain a comfortable environment on cooler days and
nights than on moderate ones.
SUPPLEMENTAL HEAT
Your heat pump is your primary heating source.Your system
mayalso be equipped withasupplementalheating source such
aselectricheat.Oncolddaysand nights, your systemwillauto-
matically turn on the supplemental heat in order to maintain
the level of comfort you have selected.
When your heat pump needs additional heat to keep you com-
fortable, your Carrier electronic thermostat will turn on the
supplemental heat (if equipped) and will display the “AUX
HT” message.
DEFROST MODE
When your heat pump is providing heat to your home or office and
the outdoor temperature drops below 45°F, moisture may begin to
freezeonthesurfaceofthecoil.Ifallowedtobuildup,thisicewould
impede airflow across the coil and reduce the amount of heat
absorbed from the outside air. So, to maintain energy-efficient
operation, your heat pump has an automatic defrost mode.
The defrost mode starts at a preset time interval of 90 minutes,
although, it may be reset to either 30 or 50 minutes. Defrost
will start at the preset time only if the ice is sufficient to inter-
fere with normal heating operation.
After the ice is melted from the coil, or after a maximum of 10
minutes in defrost mode, the unit automatically switches back
to normal heating operation.
Do not be alarmed if steam or fog appears at the outdoor unit
during defrost mode. Water vapor from the melting ice may
condense into a mist in the cold outside air.
During certain weather conditions such as heavy snow and
freezing rain it is not uncommon for ice to build up on the unit
grille. This is normal for these weather conditions. Do not
attempt to remove the ice from the unit grille. This condition
will not affect the proper function of the unit and will clear
within a few days.
EMERGENCY HEAT MODE
This allows your supplemental heating source to keep your
homeorofficewarmuntil your heatpumpcanbeserviced.Also,
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 your 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:
CHECKTHE AIR FILTER
A dirty air filter will cause excessive strain on the compressor
and blower motor. This can cause the components to over-heat
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.
WARNING
Disconnect all electrical power to the indoor air han-
dler or furnace before removing access panels to per-
form any maintenance. Disconnect power to the unit.
Note: There may be more than 1 electrical disconnect
switch. Electrical shock could cause severe injury or
death.
CAUTION
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.

below room temperature and the SYSTEM or MODE control
is set to COOL or AUTO. If you require warmth, make sure
that the temperature control selector is set above room temper-
ature and the SYSTEM or MODE control is set to HEAT or
AUTO. The FAN control should be set to ON for continuous
blower operationorAUTOifyou wish blowerto functiononly
while your heat pump is operating.
If your comfort system still fails to operate, turn your system
off and contact your servicing dealer for troubleshooting and
repairs. Specify your apparent problem, and state the model
and serial number of your equipment. (You should have them
recorded on the last page of this booklet.) With this informa-
tion, your dealer may be able to offer helpful suggestions over
the phone or save valuable time through knowledgeable prep-
aration for the service call.
REGULAR DEALER MAINTENANCE
In addition to the routine mainte-
nancethatyouperform, your home
comfort system should be inspect-
ed 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 coils.
• A check of all electrical wiring and connections.
• A check for secure physical connections of individual com-
ponents within unit.
• Operational check of the heat pump 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.

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.
The filters(s) and filter rack for a packaged system are supplied
andinstalledbythecontractorordealer.Typically,thefilter(s)and
rackare located inthereturn-airductat the outdoorunitorbehind
the return-air grille(s). Have your dealer show you the location of
your filter(s) and the procedures for removal and replacement.
If your system includes a high efficiency or electronic air
cleaner, refer to air cleaner User’s Manual for proper filter
cleaning or replacement.
OUTDOOR COIL
If grass clippings, leaves, shrubbery, and debris are kept away
from the unit, minimal care should be sufficient to keep the
system functioning properly. However, 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. 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
mostmetals.Although your newunit is made out of galvanized
metal and is protected by top-grade paint, you should take the
precaution of additional maintenance which consists of peri-
odicallywashingtheunit.Bywashingallexposedsurfacesand
coil, you will be adding additional life to your unit. Please con-
sult your installing contractor for proper intervals/procedures
for your geographic area or service contact.
UNIT SUPPORT
Your packaged heat pump 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 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.
