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
when handling parts or reaching into the unit.
• 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.
• 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" (304.8 mm) minimum clearance between the
outdoor unit and tall grass, vines, shrubs, etc.
• 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.
• Do Not Operate Below 55°F/12.78°C ill 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.
• 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.
• Base Pall 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 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:
• 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 themmstat settings. For cooling, your desired
temperature setting should be LOWER than the displayed
room temperature, and the System_ode control should be on
Cool or Auto. For heating, your temperature setting should be
HIGHER than the displayed room temperature, and the
System_ode control is set to Heat or Auto.
• Time delays - depending on the Carrier heat pump you have,
there may be delays m unit operation that are built-in to protect
the equipment and your comtbrt. Don't be alarmed if you
notice a time delay m operation. It may be a standard
protection feature of your equipment. Check with your Carrier
Dealer for more infommtion 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).
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. Some service contracts offer
additional benefits such as parts discounts and no additional charge
for "after hours" or emergency service.
Your annual system inspection should include:
• Routine inspection of air filter(s) with replacement or cleaning
as required
• Inspection and cleaning of the blower wheel housing and
motor
• Inspection and, if required, cleaning of indoor and outdoor
coils
• Inspection of the indoor coil drain pan, as well as the primary
and secondapy drain lines. If the system has an auxiliary drain
pan and line, they should be inspected at this time as well.
Service should include cleaning if required.
• Check all electrical wiring and connections
• Check for secure physical connections of individual parts in
each unit
• Operational check of the heat pump system to determine actual
working condition. Necessary repair and, or adjustment should
be performed at this time.
