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
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.
INFINITY OPERATION
If you own an Infinity two- -stage heat pump system, you may
notice your system runs for longer periods of time. 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.

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:

S More than the usual number of people present in the home

IMPORTANT HEAT PUMP FACTS
use
Heat pump systems have a few unique features and operations that
you should be aware of:
S 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° to about 105° F,
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.
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.
S Heat pumps installed in areas expecting snow are elevated with
support feet.

heat pump system's ability to operate economically and
