YOUR COMFORT SYSTEM
I. IDENTIFYING YOUR SYSTEM
Take the time to familiarize yourself with your packaged heat
pump type of 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 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 in the space provided at the
end of this booklet.
SAFETY CONSIDERATIONS
Recognize safety information. This is the safety-alert symbol .
When you see this symbol on unit or in instructions and manuals,
be alert to potential for personal injury.
IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary
calls, familiarize yourself with the following facts:
1. 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.
2. 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.
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 is used to highlight
suggestions which will result in enhanced installation, reliability,
or operation.

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 for heat pump systems have 3 controls: a temperature
control selector, a FAN control, and a SYSTEM or MODE control.
3. The outdoor unit must have unrestricted airflow. Do not
cover the unit, lean anything against it, or stand on it. Do
not allow grass clippings, leaves, or other debris to accumulate around on top of the unit. Maintain a 12-in.
minimum clearance between the outdoor unit and tall grass,
vines, shrubs, etc.
I.
COOLING MODE
4. 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. 4 and 5.)
5. During heating, increasing the thermostat setting more than
2 degrees 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.
6. 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. 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.
Fig. 3—Bryant Non-Programmable Thermostat
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. Your heat pump will work longer to keep
your home comfortable under these conditions:
7. 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.
1. Entrance doors are frequently opened and closed
8. Your system may also be equipped with a zoning system
which allows individual control over the temperatures of
separate areas of your home.
2. Laundry appliances are being operated
3. A shower is running
4. More than the usual number of people are present in the
home
9. Your heat pump will remove humidity from your home
during the cooling season. After a few minutes of operation,
you should be able to see water trickle from the condensate
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.
5. More than the normal number of electric lights are in use
6. Drapes are open on the sunny side of the home
II. 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 for longer periods to maintain
a comfortable environment on cooler days and nights than on
moderate ones.
10. 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
furnace. This air may feel cooler because it is slightly less
than your skin temperature. However, it is sufficiently
warm to keep you comfortable.
III. SUPPLEMENTAL HEAT
Your heat pump is your primary heating source. Your system may
also be equipped with a supplemental heating source such as
electric heat. 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.
11. Ice or frost will tend to form on the coil during the winter
heating 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!

FILTER SIZE DATA
When your heat pump needs additional heat to keep you comfortable, your Bryant electronic thermostat will turn on the supplemental heat (if equipped) and will display the “AUX HT” message.

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 coil. If allowed to build 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 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 interfere 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 a few days.
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:

If your system includes a high efficiency or electronic air cleaner,
refer to air cleaner User’s Manual for proper filter cleaning or
replacement.
II. 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.
III. 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. Please consult your installing
contractor for proper intervals/procedures for your geographic area
or service contact.
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 serious injury or death.
IV. 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.
CAUTION: Although special care has been taken to
minimize sharp edges in the construction of your unit, to
avoid injury be extremely careful when handling parts or
reaching into the unit.
BEFORE YOUR REQUEST A "SERVICE CALL"
CHECK FOR THESE EASILY SOLVED PROBLEMS:
1. Check the indoor and outdoor disconnect switches. Verify
that circuit breakers are ON or that fuses have not blown.
I. CHECK THE AIR FILTER
A dirty air filter will cause excessive strain on the compressor and
blower motor. This can cause the components to overheat 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.
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 two 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
and installed by the contractor or dealer. Typically, the filter(s) and
rack are located in the return-air duct at the outdoor unit or behind
the return-air grille(s). Have your dealer show you the location of
your filter(s) and the procedures for removal and replacement.
2. Check for sufficient airflow. 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.
3. 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
for continuous blower operation or AUTO if you wish
blower to function only 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 information, your dealer may be able to offer
helpful suggestions over the phone or save valuable time
through knowledgeable preparation for the service call.
