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.

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.
CAUTION
!
S 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 indoor unit literature.
S 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.
S 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” (304.8 mm) minimum clearance between the
outdoor unit and tall grass, vines, shrubs, etc.
S Check 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.
S Do 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.
S 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.
S 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 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:
S Check the indoor and outdoor disconnect switches Also check
your main electrical panel circuit breakers or fuses.
S Check for sufficient airflow. Air filter(s) should be reasonably
clean and interior vents should be open and unobstructed.
S Check 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.
S Time 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).
