YOUR COMFOR T
SYSTEM
Identifying Y our System
Take time to get to know the type of
system you have. This will be helpful in
understanding the basic operation of your
new heat pump.
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 information
for specific identification of a unit. You
should familiarize yourself with the
product, model, and serial numbers listed
on each rating plate. Record them for
future reference on the last page of this
booklet.
IMPORTANT FACTS
T o better protect your investment and to
eliminate unnecessary service calls, familiarize yourself with the following facts:
Keep Filter Clean
Y our heat pump system should ne v er be
operated without a clean air filter properly installed. Plan to inspect the filter
once per month. A clogged air filter will
increase operating costs and shorten the
life of the unit.
Do Not Block Registers
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.
Do Not Cover or Block
Outdoor Unit
The outdoor unit must have unrestricted
airflow. Do not cover the unit, lean
anything against it, or stand upon it. Do
not allow grass clippings, lea ves, 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.
Get to Know Your Thermostat
Your multipurpose indoor thermostat is
the control center for your heat pump
system. Y ou should f amiliarize yourself
with its proper operation. (See Fig. 2 and
3.) Attempting to control the system by
other means—for instance, switching the
electrical supply power ON and OFF—
may cause damage to the unit.
During heating, increasing the
thermostat 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.
Continuous Fan
You may find that you can maintain
greater personal comfort by running the
fan continuously. Air pockets can form
due to the structure of the house, placement of registers, etc. These air pock ets
may be too cool or warm for your liking.
Continuous fan operation minimizes any
temperature differences.
Air Cleaners and Humidifiers
Systems equipped with electronic or
mechanical air cleaners and/or humidi-
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 agency
must use factory-authorized
kits or accessories when modifying this product.

Check Condensate Drain
Your heat pump system will remove
humidity from your home during the
cooling season. After a fe w minutes
of operation, you should be able to see
water trickle from the condensate drain
of the 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 v ery dry
environment.

Heated Air Temperatur e
During the heating cycle, air from your
registers may seem cooler than you might
first expect. This is because the air is being
delivered at a higher v elocity and a more
constant flow than air supplied by a conventional furnace. Also, your heat pump
supplies air at 90 to 105°F instead of in
sudden bursts of hot air as with a conventional furnace. The air may feel cool
because it is slightly less than your body
temperature. Howev er, it is sufficiently
warm to keep you comfortable.

Don’t W orry About Ice
On Y our Unit
Ice or frost will tend to form on the
outdoor coil during the winter heating
operation. Y our 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!
When Not To Use Your Unit
Do not operate your unit in cooling
mode when outdoor temperatures are
below 55°F.
Do not operate your unit in heating mode
when outdoor temperatures are above 66°F.
OPERA TING 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 for
heat pump systems have three controls: a
temperature control selector, a FAN control, and a SYSTEM or MODE control.
The temperature control selector is a dial,
lever , or set of b uttons that allo ws you to
establish the degree of temperature that
you wish to maintain for your personal
comfort. Some thermostats possess
two temperature control selectors: one
for setting the temperature desired during
the cooling cycle, and one to set the heating operation temperature.
The FAN control offers two options for
controlling the indoor blower: AUT O and
ON. When set to A UT O, the blower runs
only during the time the heat pump is
operating. When set to ON, the blower
will run continuously.
Typically, the SYSTEM or MODE control on your thermostat offers the follo wing selections: COOL, OFF, HEAT,
AUTO, and EMERGENCY HEAT.
Some thermostats may have a separate
switch for EMERGENCY 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
operate in cooling mode when the indoor
temperature rises above the le vel that you
wish to maintain. With the SYSTEM or
MODE control set to HEAT , your heat
pump will provide warmth whene ver the
indoor temperature falls below the level
that you have selected.
The A UT O selection found on some thermostats provides for automatic changeover between cooling and heating c ycles.
With the SYSTEM or MODE control set
to AUTO, cooling mode is activ ated
when the indoor temperature rises above
the thermostat cooling temperature setting, or heating mode is activ ated when
the indoor temperature drops below the
thermostat setting for the heating cycle.
Depending on your typical winter heating
needs, your home comfort system may
include a supplementary heating source.
The EMERGENCY HEAT setting
(EHEAT) provides for conv enient selection between the two 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 off and the supplementary heat
source will be activated.
NOTE: Y our 2-speed heat pump system
has several special features b uilt in to protect the unit.
• 5-MINUTE TIME DELA Y—Unit will
delay operation upon initial start-up or
short-cycling of the indoor thermostat.
• 1-MINUTE TIME DELA Y—When
changing speeds from low to high, or high
to low , there is a 1 minute time delay . During the speed change delay, the outdoor
fan will continue to run.
• 1-MINUTE HIGH-SPEED MINIMUM—If the unit has not operated within the past 12 hours or has a power
interruption, upon the next cooling
demand, it will operate for a minimum of
1 minute on high speed.
In certain geographic areas and in certain applications, supplemental heat is
not required. Any questions regarding
your application should be directed to
your dealer.
Your thermostat may be PROGRAMMABLE or NON-PROGRAMMABLE. A NON-PROGRAMMABLE
thermostat (See Fig. 2.) does not allow
the temperature settings to be varied
throughout the day or week without
physically changing the settings. A
PROGRAMMABLE thermostat (See
Fig. 3.) allows various daily temperature changes to be preset. During the
winter 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 f amily returns
home. During the summer, the opposite
changes might be programmed. When
properly used, this programming can
result in energy savings on your home’ s
heating and cooling.
If you wish to program your accessory
electronic indoor thermostat, please refer
to thermostat Owner’ s Manual.
COOLING CYCLE
When operating in cooling cycle, your
heat pump will run until the indoor
temperature is lowered to the le vel you
have selected. On extremely hot days,
your unit will run for longer periods at a
time and have shorter of f periods than on
moderate days.
Your 2-speed heat pump spends about
80% of its time operating in low-speed
cooling. This means that it will operate
for longer periods of time than a singlespeed heat pump even on moderate days.
This longer operational time in low speed
results in higher efficiency operation,
lower operating noise, and better humidity control than a single-speed heat pump
could achieve.
The following are typical conditions that
add extra heat and/or humidity to your
home. Your unit will work longer to keep
your home comfortable under these
conditions:
• Entrance doors are frequently opened
and closed
• Laundry appliances are being operated
• A shower is running
• More than the usual number of people
are present in the home
• More than the normal number of
electric lights are in use
• Drapes are open on the sunny side of
the home
HEATING CYCLE
With the SYSTEM or MODE control
of your indoor thermostat set to HEAT ,
the heating section of your home comfort system will operate until room
temperature is raised to the level you
have selected. Of course, the heating
unit will have to operate for longer periods to maintain a comfortable environment on cooler days and nights than on
moderate ones.
Your 2-speed heat pump spends about
80% of its time operating in low-speed
heating. This means that it will operate
for longer periods of time than a singlespeed heat pump even on moderate days.
This longer operational time in low speed
results in higher efficiency operation and
lower operating noise than a single-speed
heat pump could achieve.
SUPPLEMENTAL HEA T
Your heat pump is your primary heating
source. Your system may also be
Page 5
5
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 you have selected.
Your Bryant electronic thermostat will
display the words ENERGY SAVINGS
when the heat pump is providing all the
heat that is necessary. When
additional heat is required, your thermostat will turn on the supplemental heat
(if equipped) and will display the
AUX HT message.
DEFROST CYCLE
When your heat pump is providing heat
to your home and the outdoor temperature drops below 45°F, moisture may
begin to freeze on the surface of the
outdoor coil. If allowed to b uild up, this
ice would 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 cycle.
The defrost cycle starts at a preset time
interval of 90 minutes, although, it may
be reset to either 30 or 50 minutes by your
dealer. Defrost will start at the preset time
only if the ice is sufficient to interfere
with normal heating operation.
After the ice is melted from the outdoor
coil, or after a maximum of 10 minutes
in the defrost mode, the unit will
automatically switch back to normal
heating operation.
Do not be alarmed if steam or fog appears
at the outdoor unit during the defrost
cycle. 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
outdoor unit grille. This is normal for
these weather conditions. Do not attempt
to remove the ice from the outdoor unit
grille. This condition will not af fect the
proper functioning of the unit and will
clear within a few days.
EMERGENCY HEAT
The emergency heat (EHEAT) setting on
your Bryant electronic thermostat can be
used to turn off your heat pump and use
only the supplemental 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, howe v er, where
it is necessary . Y our Bryant programmable
electronic thermostat has a service alarm
indicator. In the heating season, if the ther mostat ever displays the TROUBLE message, switch your thermostat to EHEAT
mode and call your dealer . This allo ws
your supplemental heating source to keep
your home warm until your heat pump can
be serviced. 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 necessary to exceed 12 hrs.
If you 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 unit will operate
economically and dependably . Maintenance can be accomplished easily by referring to the following directions. Ho we ver,
before performing maintenance, consider
these important safety precautions.
!
WARNING
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 1
electrical disconnect switch. Electrical shock can cause personal injury
or death.
!
CAUTION
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.
CHECK THE AIR FIL TER
A dirty air filter will cause excessi ve strain
on the compressor and blower motor . This
can cause the components to overheat and
automatically shut down. In the extreme,
the components will fail and need to be
replaced. To avoid inefficient or f ailed
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, ne w 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
COMPLETEL Y DR Y BEFORE BEING
REINSTALLED. T o avoid prolonged
shutdown of your unit while a filter is
drying, you should have an e xtra filter on
hand. This allows you to rotate between
the two filters with minimal downtime
for your comfort system. Extra filters
may be purchased from your dealer.
There are no filters in the outdoor unit of
a split system. If your indoor unit is a gas
or oil furnace, refer to your furnace
User’s Manual for fi lter location and procedures for replacement or cleaning.
If your system includes an indoor fan 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 to ward center of plate. Lift filter to clear lower flange.
Filter is spring-loaded and will pop out.
Reinstall filter, being certain to secure fi lter 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.
INDOOR COIL
If the indoor 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 rinse it with water. This could
Page 6

require the removal of the coil.
DO NOT attempt this yourself.
Fig. 5—Removing Filter
from Fan Coil Unit
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
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 coil 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 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 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 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 that 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
A SER VICE CALL
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 airflo w. Check
the air filter(s) for any accumulations of
dirt. Check for blocked return-air or
supply-air registers. Be sure registers 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 or MODE control is set to
COOL or AUTO. If you require
warmth, be sure the temperature control
selector is set above room temperature
and the SYSTEM or MODE control is
set to HEA T or A UTO. The F AN control
should be set to ON for continuous
blower operation or AUTO if you wish
blower to function only while the unit is
operating.
• Check note concerning special features and time delays in “Operating
Your Heat Pump” section.
If your comfort system still fails to
operate, contact your servicing dealer for
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
helpful suggestions over the phone or sa ve
valuable time through kno wledgeable
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 e v ery 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 components within units.
• 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.
