DANGER identifies the most serious hazards which will result in severe personal injury or death.

!WARNING

PERSONAL INJURY, DEATH AND / OR PROPERTY DAMAGE HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer, service agency, or your distributor or branch for information or assistance. The qualified installer or service agency must use factory-authorized kits or accessories when modifying this product.

Read and follow all instructions and warnings, including labels shipped with or attached to unit before operating your new air conditioner.

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:

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

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:

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.

!WARNING

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.
