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.
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.

WARNING: Improper installation, adjustment, alter-
ation, service, maintenance, or use can cause explosion,
fire, electrical shock, or other conditions which may
cause serious injury, death 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.
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.
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.

12. Do not operate your unit in cooling mode when outdoor
temperaturesarebelow40˚Funlessyourunitwasmodified
for low-ambient operation.
13. Do not operate your unit in heating mode when outdoor
temperatures are above 66˚F unless you set your thermostat
to emergency heat mode.
WARNING: To prevent serious 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.

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.
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.
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.
8. Your system may also be equipped with a zoning system
which allows individual control over the temperatures of
separate areas of your 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.
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.
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!
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.
I. COOLING MODE
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:
1. Entrance doors are frequently opened and closed
2. Laundry appliances are being operated
3. A shower is running
4. More than the usual number of people are present in the
home
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.
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.
