WARNING
ABOUT YOUR HEAT PUMP SYSTEM
Our products are designed, tested and built in accordance
with DOE standardized procedures; however, actual operating
results and efficiencies may vary based on manufacturing and
supplier tolerances, equipment configuration, operating
conditions and installation practices.
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 on the warranty included in this booklet.
USING YOUR NEW SYSTEM
Your heat pump system is controlled by a wall- mounted
Observer
®
Wall Control or thermostat installed inside your
home. See the Observer
®
Wall Control or thermostat
Homeowner Guide for more details on system operation.
VARIABLE SPEED OPERATION
You may notice your system runs for longer periods of time.
This system is designed to meet cooling or heating needs of
the home at a wide range of conditions. 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 Observer Wall Control or
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:
S Frequent opening of exterior doors
S Operating laundry appliances
S Taking hot showers
S More than the usual number of people present in the
home
S More than the normal number of electric lights in use
S 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:
S During the heating cycle, your heat pump delivers a
constant flow of air at around 95 ° to about 105° F,
compared to sudden blasts of hot air provided by a typical
furnace.
S 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.
At the beginning and end of the defrost cycle, you may
hear a ”whoosh” sound coming from the unit. This is
normal for heat pump applications.
S Heat pumps installed in areas expecting snow are
elevated with support feet.
SOUND
Your new heat pump with SmartSenset technology is
different from most heating and cooling systems. Because this
is a variable speed system, it is designed to operate at
different speeds depending on the temperature and humidity
conditions. You may notice the sound coming from the
outdoor unit changing from time to time, and from season to
season. In winter, the system will operate at higher speeds as
it gets c older outside to maintain its heating performance. The
higher speed produces a higher sound. This change of speed
allows the system to operate more efficiently and maintain
comfortable conditions inside the home. You may also hear a
slight hissing sound when near the outdoor unit in the
off- cycle. This is the sound of system pressure equalization
which is required to enable s oft and easy starting of the next
cycle. These sounds are normal and do not represent a
problem with your system.
ROUTINE MAINTENANCE
Simple, routine maintenance as described below will enhance
your heat pump system’s ability to operate economically and
dependably. Always remember the following safety
precautions:
S Keep Filter Clean
A clogged or improperly installed air filter on your indoor unit
will increase operating costs and shorten the life of the unit.
For detailed filter cleaning information refer to indoor unit
literature.
