ABOUT YOUR AIR CONDITIONING SYSTEM
Identifying Your System
Your new Carrier air conditioning 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 air conditioning 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 air conditioning 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.
COOLING YOUR HOME
For cooling operation, make sure the System or Mode control is set
for Cooling. Then, adjust the Temperature control to your desired
setting. Finally, use the Fan control to select Automatic (turns on
and off as cooling is needed) 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 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 m the home
• More than the nom_al number of electric lights in use
• Drapes or blinds are open on the sunny side of the home
ROUTINE MAINTENANCE
Simple, routine maintenance as described below will enhance your
air conditioning system's ability to operate economically and
dependably. Always remember the following safety precautions:
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Disconnect all electrical power to the indoor air handler or
furnace before removing access panels to perform any
maintenance. Disconnect power to both the indoor and
outdoor units.
NOTE: There may be more than one electrical disconnect switch.
