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 identity unsafe practices which would result in minor
personal injury or product and property damage. NOTE is used
to highlight suggestions that will result in enhanced installation, reliability, or operation.

Fig.l--Typical

Split-System Installation

The type of heat pump you have purchased is a split system.
The split-system type has an indoor and an outdoor unit, each
of which contains a coil. These units are interconnected by
refrigerant tubes. (See Fig. 1.)
Each unit has a rating plate affixed to it which provides necessary int\)rmation t\_r specific identification of a unit. You should
familiarize yourself with the product, model, and serial numbers listed on each rating plate. Record them t_r future reference on the last page of this booklet.

IMPORTANT

FACTS

To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the t\_llowing facts:
Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion,
fire, electrical shock, or other conditions which
may cause personal injury or property damage.
Consult a qualified installer, service agency, or
your distributor or branch for information or assistance. The qualified installer or service agency
must use factory-authorized
kits or accessories
when modifying this product.

To prevent personal injury, death, or property
damage, read and follow all instructions and warnings, including labels shipped with or attached to
unit before operating your new heat pump.

• Your heat pump system should never be operated without a
clean air filter properly installed. Plan to inspect the filter periodically. 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
t\_und obstructing
registers. Restricted
airflow lessens the
unit's efficiency and life span.
• The outdoor unit must have unrestricted
airflow. Do not coverthe 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--f_)r
instance, switching the electrical supply
power ON and OFF--may
cause damage to the unit. (See Fig.
2 and 3.)

Identifying Your System

• During heating, increasing the thermostat
setting more than
2 degrees may cause the supplemental
heaters to be turned on
to satisfy the thermostat.
Needless use of the supplementary
heat reduces potential energy savings.

Take the time to familiarize yourself with the type of system
you have. This knowledge will be of use in understanding the
basic operation of your new heat pump.

• You may find that you can maintain greater personal comt\_lt by running the fan continuously.
"Air pockets" can t\)rm
due to the structure of the house, placement of registers, etc.

ing the cooling season. After a few minutes of operation, you
should be able to see water trickle from the condensate drain
of the indoor cooling coil. 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.

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.

• 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 in sudden bursts of hot air as with a conventional
furnace. This air may feel cool because it is slightly less than
your skin temperature. Howevel: it is sufficiently warm to
keep you comt\_rtaMe.

• A system equipped with a heat or energy recovery ventilator
offers the advantage of exhausting stale air from the home and
allowing fresh air in from the outdoors while minimizing
heat
loss.

• Your system may also be equipped with a zoning system
which allows individual control over the temperatures of separate areas of your home.

• Ice or fiost will tend to form on the outdoor coil during the winter
heating operation. Your heat pump is designed to automatically

• Your heat pump will remove humidity from your home dur-

fog to rise from the outdoor unit. Do not be alarmed!
• Do not operate your unit in cooling mode when outdoor
temperatures
are below 55°F unless your unit was modified
l\_r low-ambient
operation.
• Do not operate your unit in heating mode when outdoor
temperatures
are above 66°F unless you set your thermostat
to emergency heat mode.

OPERATING

YOUR 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 l\_r heat pump systems have 3 controls: a temperature control selector, a FAN control, and a SYSTEM or
MODE control.
The temperature control selector is a dial, level, or set of buttons that allows you to establish the temperature that you wish
to maintain l\_r your personal coml\_rt. Some thermostats have
2 temperature control selectors: 1 l\w setting the temperature
desired during cooling operation, and 1 for setting the temperature desired during heating operation. A typical setting l\_r
year-round coml\_rt is 72°E
The FAN control offers 2 options for controlling the blower: AUTO
and ON. When set to AUTO, the blower runs only when the heat
pump is operating. When set to ON, the blower runs continuously.
Typically. the SYSTEM or MODE control on your thermostat
offers the l\_llowing selections: COOL, OFR HEAT, AUTO,
and EMERGENCY HEAT. Some thermostats may have a separate switch l\_rEMERGENCY HEAT. The heat pump will not
operate when the SYSTEM OR MODE control is set to OFF.
With the SYSTEM or MODE control set to COOL, your heat
pump will provide cooling when the indoor temperature rises
above the level you wish to maintain. With the SYSTEM or
MODE control set to HEAT, your heat pump will provide
warmth whenever the indoor temperature falls below the level
that you have selected.
The AUTO selection l\mnd on some thermostats provides l\_r
automatic changeover between cooling and heating. With the
SYSTEM or MODE control set to AUTO, cooling operation is
activated when the indoor temperature rises above the thermostat cooling temperature setting, or heating operation is activated when the indoor temperature drops below the thermostat
heating setting.
Depending on your typical winter heating needs, your home comfort system may include a supplementary heating source. The
EMERGENCY HEAT setting (EHEAT) provides for convenient
selection betweeu the 2 heating appliances. Your heat pump will
operate when the SYSTEM or MODE control is set to HEAT.With
the SYSTEM or MODE control set to EHEAT, the heat pump will
turn offand the supplementzuy heat source will be activated.
In certain geographic areas and in certain applications, supplemental heat is not required. Any questions regarding your
application should be directed to your dealel:
Your thermostat may be PROGRAMMABLE or NON-PROGRAMMABLE. A NON-PROGRAMMABLE thermostat does
not allow the temperature settings to be varied throughout the day
or week without physically changing the settings. A PROGRAMMABLE thermostat allows various daily temperature changes to
be preset. During the wintel; for example, you may wish to "set
back" the temperature of your home at night, then have the temperature return to normal prior to waking up. The home's temperature can then be lowered again during the day when no one is at

home, but again be at peak comfort level when your family returns
home. During the summel; the opposite changes might be programlned. When properly used, the programming can result in
energy savings on your home's heating and cooling.

COOLING

MODE

When operating in cooling mode, yonr heat pump will nln in
cooling mode until the indoor temperature
is lowered to the
level you have selected. On extremely
hot days, your heat
pump will run l\_r longer periods at a time and have shorter
"off' periods than on moderate days.
The l\_llowing are typical conditions that add extra heat and/or
humidity to your home. Your heat pump will work longer to
keep your home coml\_rtable
under these conditions:
• Entrance

doors are frequently

• Laundry

appliances

• A shower

• More than the usu_d number of people ale present in the home,
• More than the normal
• Drapes

number

lights are in use,

are open on the sunny side of the home.

HEATING

MODE

With the SYSTEM or MODE control of your indoor thermostat set to HEAT, your heat pump will run in heating mode until
room temperature
is raised to the level you have selected. Of
course, your heat pump will have to operate l\_r longer periods
to maintain a coml\_rtable environment
on cooler days and
nights than on moderate ones.

SUPPLEMENTAL

HEAT

Ygur heat pnmp is yonr primary heating sonrce. Ygnr system
may also be equipped with a supplemental
heating source such
as electric, gas, or oil. On cold days and nights, your system
will automatically
turn on the supplemental
heat in order to
maintain the level of comfort your have selected.

DEFROST

MODE

When yonr heat pnmp is providing heat to yonr home and the
outdoor temperature
drops below 45°F, moisture may begin to
freeze on the surface of the outdoor coil. If allowed to build up,
this ice would impede airflow across the coil and reduce the
amount of heat absorbed from the outside all; So, to maintain
energy-efficient
operation, your heat pump has an automatic
defrost mode.
The defrost

delay.

Do not be alarmed if steam or l\_g appears at the outdoor unit
during defrost mode. Water vapor from the melting ice may
condense into a mist in the cold outside all:

During certain weather conditions such as heavy snow and
freezing rain it is not uncommon l\_r ice to bnild up on the
outdoor unit grille. This is normal l\_rthese weather conditions.
Do not attempt to remove the ice from the outdoor unit grille.
This condition will not affect the proper fnnction of the unit
and will clear within a few days.

EMERGENCY

HEAT MODE

The emergency heat (EHEAT) setting on your Carrier electronic thermostat can be used to turn off your heat pump and use
only the suppleruental heating source (if equipped). The Auxiliary Heat Indicator (AUX HT) will be displayed while your
system is operating in EHEAT mode.
Emergency heat is not normally used. There may be situations, however, when it is necessary, such as when your heat
pump requires servicing.
If the electricity to your heat pump has been off l\_r more than
30 minutes, switch your thermostat to EHEAT mode before
restarting your heat pump. Leave the system in EHEAT mode
l\_r an amount of time equal to the power outage. It is not
necessary to exceed 12 hrs. If you cannot determine how long
the power has been off, leave the system in EHEAT mode l\_r
8 hrs.

Although special care has been taken to minimize
sharp edges in the construction of your unit, be
extremely careful when handling parts or reaching
into the unit. Failure to follow this caution could
result in minor personal injury or product and
property damage.

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 components 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.
Disposable filters should be replaced by similar, new filters of
the same dimensions.

MAIN
ON

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 shutdown 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 coml\_rt system. Extra filters
may be purchased from your dealel:
There are no filtel.Sin the outdoor unit of a split system. If your
indoor unit is a gas or oil furnace, refer to your filrnace User's Manual for filter location and procexlures for replacement or cleaning.

PERFORMING ROUTINE
MAINTENANCE

If your system includes an indoor tim coil unit, the filter may be
located in the unit where it connects with the return-air duct or
plenum. (See Fig. 5.) Remove the filter 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
instance the filter may be located behind the return air grille.
Access the filter by removing the return air grille.
If your system includes a high efficiency or electronic air
cleaner, refer to air cleaner User's Manual l\_r proper filter
cleaning or replaceruent.

With the proper maintenance and care, your heat pump will
operate economically and dependably. Maimenance can be
accomplished easily by referring to the l\41owing directions.
However, bet\_re ped\_rming maintenance, consider these
important safety precautions:

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. NOTE: There may be more
than one electrical disconnect switch.
Electrical
shock can cause personal injury or death.

Fig. 5--Removing

Filter from

Fan Coil Unit

INDOOR

COIL

If the split-system 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
nnse 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
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. The
outdoor fan motor may have to be disconnected and the top
panel removed to gain access to the coil t\_r thorough cleaning.
Do not attempt this yourself.

OUTDOOR

COILmSEA

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 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. Please consult your installing contractor t\_r proper intervals/procedures
for your geographic area or service contact.

UNIT SUPPORT
Yonr split-system ontdoor nnit 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.
Heat pumps installed in snowbelt areas should be elevated with
support feet or a snow stand.

BEFORE YOU REQUEST
"SERVICE CALL"
CHECK FOR THESE
PROBLEMS:

EASILY SOLVED

• Check the indoor and outdoor disconnect switches. Verily
that circuit breakers are ON or that fuses have not blown.
• Check t\_r sufficient airflow. Check the air filter(s) t\_r any
accumulations of dirt. Check t\_r blocked return-air or supplyair registers. Be sure registers are open and unobstructed.
• Check the settings on your indoor thermostat. If you desire
cooling, make sure 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, make sure
that the temperature control selector is set above room temperature and the SYSTEM or MODE control is set to HEAT or
AUTO. The FAN control should be set to ON t\_r continuous
blower operation or AUTO if you wish blower to function only
while your heat pump is operating.
If your comt\_rt system still fails to operate, turn your system
off and contact your servicing dealer t\_r troubleshooting and
repairs. Specify your apparent problem, and state the model
and serial numbers of your equipment. (You should have them
recorded on the last page of this booklet.) With this information, your dealer may be able to offer helpfnl suggestions over
the phone or save valuable time through knowledgeable preparation t\_r the service call.

REGULAR DEALER
MAINTENANCE
In addition to the routine maintenance that you pert\_rm, 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 t\_llowing:
• Routine inspection of air filter(s). Replacement
as required.

or cleaning

• Inspection and cleaning of the blower wheel, housing, and
motor as required.
• Inspection and, if requiled, 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 t\_r secure physical connections of individual components within units.
• Operational check of the heat pump system to determine
actual working condition. Necessary repair and/or adjustment
should be pert\_rmed at this time.
• Your servicing dealer may offer an economical service
contract that covers seasonal inspections. Ask t\_r further
details.

FOR THE RECORD
