About Your Air Conditioning 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.
Identifying Your System
Your new Carrier 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 number on it. You will need these numbers when
calling an authorized Carrier dealer about your system.
Using Your New Carrier System
Your Carrier air conditioning system is controlled by a wall-mounted
Infinity Control installed inside your home. 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 the cooling 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.

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 Infinity 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:
• 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
Sound
Your new variable speed air conditioner is different from most cooling
systems. Because this is a variable speed system, it is designed to operate
at varying 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.
variations are normal and do not represent a problem with your system.
