in manuals, instructions and on the
unit, be aware of the potential for personal injury. There are three levels
of precaution:
DANGER
identifies the most serious hazards which will result in severe
personal injury or death.
WARNING
signifies hazards that could result in personal injury or
death.
CAUTION

ABOUT YOUR HEAT PUMP SYSTEM
Our products are designed, tested and built in accordance with US
Department of Energy standardized procedures and other standards;
however, actual operating results and efficiencies may vary based on
manufacturing and supplier tolerances, equipment configuration,
operating conditions and installation practices.º °
Identifying Your System
Your new heat pump system is what we call a ”split system.” It has an
outdoor unit and an indoor unit connected to each other with copper
tubing called refrigerant lines. Each of these units has a rating plate with
the model and serial numbers you will need to reference when calling an
authorized dealer about your system.
Take a few moments now to locate those numbers and record them in the
spaces provided on the cover of this booklet.
Using Your New System
Your heat pump system is controlled by a wall-mounted thermostat
installed inside your home. Because there are so many thermostats
available, please refer to the owner’s manual supplied with your
thermostat for complete details on system operation.
2-Stage Operation
If you own a two-stage heat pump system, you may notice your system
runs for longer periods of time. When appropriately sized, nearly 80%
of the time it’s running, it is operating in low-stage, and your indoor
temperature will remain more consistent with fewer drafts, better
humidity control, enhanced comfort and enhanced energy efficiency.
Heating and cooling Your Home
For heating or cooling operation, make sure the System or Mode control
is set to the appropriate mode. Then, adjust the Temperature control to
your desired setting. Finally, use the Fan control to select Automatic
(turns on and off as heating is needed) or On (runs continuously).
Depending on your typical heating needs, your home comfort system
may also include a supplementary heating source that will automatically
turn on as needed. You may also select this heat source manually if
desired.
Operation Under Extreme Conditions
Your heat pump will run as long as necessary to maintain the indoor
temperature selected on your thermostat. On extremely hot days, your
heat pump will run for longer periods at a time than on moderate days.
Your system will also run for longer periods of time under the following
conditions:
• Frequent opening of exterior doors
• Operating laundry appliances
• Taking hot showers
• More than the usual number of people present in the home
• More than the normal number of electric lights in use
• Drapes or blinds are open on the sunny side of the home
IMPORTANT HEAT PUMP FACTS
Heat pump systems have a few unique features and operations that you
should be aware of:
• During the heating cycle, air from your registers may seem cooler
than you may expect. This is because your heat pump delivers a
constant flow of air at around 90° F (32º C) to about 105° F (41º C),
compared to sudden blasts of hot air provided by a typical furnace.
This air may feel cool if it is slightly below your body temperature,
however it is warm enough to keep your home comfortable.
• Ice or frost may form on the outdoor coil during winter heating
operation. Your heat pump will automatically melt the ice using its
defrost cycle. During defrost, you may see steam or fog rising from
the outdoor unit, which is normal.
• Heat pumps installed in areas expecting snow are elevated with
support feet.
ROUTINE MAINTENANCE
Simple, routine maintenance as described below will enhance your heat
pump system’s ability to operate economically and dependably. In
addition to the routine maintenance that you perform, your home
comfort system should be inspected regularly by a properly trained
service technician. Always remember the following safety precautions:
