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. These sound variations are normal and do not represent a problem with your system.

ROUTINE MAINTENANCE

WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death. Before installing, modifying, or servicing system, make certain the main electrical disconnect switch is in the OFF position.
There may be more than 1 disconnect switch. Lock out and tag switch with a suitable warning label.
NOTE : There may be more than one electrical disconnect switch.

CAUTION
CUT HAZARD
Failure to follow this caution may result in personal injury. Although special care has been taken to minimize sharp edges in the construction of your unit, be extremely careful and wear appropriate protective clothing and gloves when handling parts or reaching into the unit.

The following simple, routine maintenance will enhance your air conditioning system’s ability to operate economically and dependably:

• Keep Filter Clean
  A clogged or improperly installed air filter on your indoor unit will increase operating costs and shorten the life of the unit. For detailed filter cleaning information refer to your indoor unit literature.

• Do Not Block Floor, Wall or Ceiling Vents
  When drapes, furniture, toys or other common household items block vents, the restricted airflow lessens the system’s efficiency and life span.

• Do Not Cover or Block Outdoor Unit
  The outdoor unit needs unrestricted airflow. Do not cover it or place items on or next to it. Do not allow grass clippings, leaves, or other debris to accumulate on the sides or top of the unit. And, maintain a 12” (305 mm) minimum clearance between the outdoor unit and tall grass, vines, shrubs, etc.

• Check Condensate Drain
  Your air conditioner removes humidity from your home during the cooling season. After a few minutes of operation, water should trickle from the condensate drain of the indoor coil. Check this occasionally to be sure the drain system is not clogged. Drainage will be limited if you live in a very dry environment.

• Operation below 55°F/13°C in cooling mode requires user to enable “Low Ambient Cooling Mode” on system control.
  Your outdoor unit requires a special operating mode when outdoor temperatures are lower than 55°F/13°C. Compressor speed range is restricted and outdoor fan may cycle to maintain proper operating pressures.

• Base Pan Drainage
  Periodically check for and remove debris that has settled around the base of your outdoor unit. This will ensure proper drainage of the base pan and eliminate standing water inside the outdoor unit.

• Level Installation
  Your Carrier dealer will install the outdoor unit in a level position. If the support base settles or shifts and the unit is no longer level, be sure to have it re-leveled promptly to assure proper drainage. If you notice water or ice collecting beneath the unit, arrange for it to be drained away from the unit.

Sea Coast Coil Maintenance
Coastal locations often require additional maintenance of the outdoor unit due to highly corrosive airborne ocean salt. Although your new Carrier system is made of galvanized metal and is protected by top-grade paint, take the additional precaution of periodically washing all exposed surfaces and the outdoor coil. Consult your installing Carrier dealer for proper cleaning intervals and procedures for your geographic area or ask about a service contract for regularly scheduled professional cleaning and inspections.

Troubleshooting

Before you request dealer service, check for these easily solved problems:

• Check the indoor and outdoor disconnect switches Also check your main electrical panel circuit breakers or fuses.
• Check for sufficient airflow. Air filter(s) should be reasonably clean and interior vents should be open and unobstructed.
• Check Infinity Control or thermostat settings. For cooling, your desired temperature setting should be LOWER than the displayed room temperature, and the System/Mode control should be on Cool or Auto.
• Time delays – There may be delays in unit operation that are built-in to protect the equipment and your comfort. Don’t be alarmed if you notice a time delay in operation. It may be a standard protection feature of your equipment. Check with your Carrier Dealer for more information on time delays.

Regular Dealer Maintenance
In addition to the routine maintenance that you perform, your home comfort system should be inspected regularly by a properly trained service technician. Many dealers offer this service at a reduced rate with a service contract.
This product has Bluetooth® functionality to enable your HVAC contractor to better service your unit. This means they can pair to your unit and read diagnostic and other outdoor equipment information as well as push outdoor equipment software updates to your unit.
