WARNING
ABOUT YOUR HEAT PUMP SYSTEM
Identifying Your System
Your new Carrier 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 Carrier
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 CARRIER SYSTEM
Your Carrier heat pump system is controlled by a wall--mounted
Infinity Control installed inside your home. This system requires
an Infinity Control which has software designed specifically to
operate this system. See the Infinity Control Homeowner Guide
for more details on system operation.
INFINITY 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 Infinity Control. 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 us-
ing 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.
