SOUND
Your new variable speed heat pump with Greenspeedt Intelligence is different from most heating and cooling systems. Because this is a variable speed system, it is designed to operate at different speeds depending on the temperature and humidity conditions. You may notice the sound coming from the outdoor unit changing from time to time, and from season to season. In winter, the system will operate at higher speeds as it gets colder outside to maintain its heating performance. The higher speed produces a higher sound. This change of speeds allows the system to operate more efficiently and maintain comfortable conditions inside the home. You may also hear a slight “purr” at start-up and shut down. These sounds are normal and do not represent a problem with your system.
ROUTINE MAINTENANCE
Simple, routine maintenance as described below will enhance your heat pump system’s ability to operate economically and dependably. Always remember the following safety precautions:
!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. Lock out and tag switch with suitable warning label.
NOTE: There may be more than one electrical disconnect switch.

!CAUTION
PERSONAL INJURY AND/OR PRODUCT AND PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in personal injury or product and property damage.
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.
SKeep 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 indoor unit literature.
SDo 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.
SDo 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” (304.8 mm) minimum clearance between the outdoor unit and tall grass, vines, shrubs, etc.
SCheck Condensate Drain
Your heat pump 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.
SDo Not Operate Below 55°F/12.78°C in Cooling Mode
Your outdoor unit is not designed to operate when outdoor temperatures are lower than 55_F/12.78_C without modification. If operation below this temperature is required, consult your Carrier dealer.
S Do Not Operate Above 66°F/18.89_C in Heating Mode
Your outdoor unit is not designed to operate on heating mode when outdoor temperatures are higher than 66°F/18.89_C. You can safely operate the system above 66°F/18.89_C on emergency or auxiliary heat.
SBase 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.
SLevel 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 re-level it 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 approximately every 3 months. 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:
SCheck the indoor and outdoor disconnect switches Also check your main electrical panel circuit breakers or fuses.
SCheck for sufficient airflow. Air filter(s) should be reasonably clean and interior vents should be open and unobstructed.
SCheck Infinity Control 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. For heating, your temperature setting should be HIGHER than the displayed room temperature, and the System/Mode control is set to Heat or Auto.
STime delays - depending on the Carrier heat pump you have, 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.
If you need to contact your Carrier dealer for troubleshooting and/or repairs, be sure to have the model and serial numbers of your equipment available (there are spaces on the cover for you to write this information).
