WARNING
ABOUT YOUR AIR CONDITIONING 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 config-
uration, operating conditions and installation practices.
Identifying Your System
Your new cooling 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 your warranty included in this booklet.
USING YOUR NEW SYSTEM
Your new air conditioning 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 the cooling needs of the
home at a wide range of conditions. Your indoor
temperature will remain more consistent with fewer drafts,
better humidity c ontrol, enhanced comfort and enhanced
energy efficiency.
COOLING YOUR HOME
For 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 or On (runs continuously).
OPERATION UNDER EXTREME CONDITIONS
Your air conditioner will run as long as necessary to
maintain the indoor temperature selected on your Observer
Wall Control or thermostat. On extremely hot days, your air
conditioner 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
SOUND
Your new air conditioner with SmartSenset technology is
different from most 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 depending on the
weather conditions. 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 as the outdoor temperature rises. 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 soft 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 y our air conditioner system’s ability to operate
economically and dependably. Always remember the
following safety precautions:
