IMPORTANT FACTS ABOUT HEAT
PUMP SYSTEMS
Heat pump systems have a few unique features and operations
that you should be aware of:
• During the heating cycle, air from your registers may seem
cooler than you may expect. This is because your heat pump
delivers a constant flow of air at around 90°F (32°C) to
about 105°F (41"C), compared to sudden blasts of hot air
provided by a typical furnace. This air may feel cool if it is
slightly below your body temperature, however it is warm
enough to keep your home comfortable.
• Ice or frost may form on the outdoor coil during winter
heating operation. Your heat pump will automatically melt
the ice using its defrost cycle. During defrost, you may see
steam or fog rising from the outdoor unit. which is normal.
• Heat pumps installed in areas expecting snow are elevated
with support feet.
GET THE MOST FROM YOUR
HEAT PUMP SYSTEM
These simple suggestions can help you enjoy years of maximum
comfort:
• Listen To Your System
Get to know the start-up and operational sounds your indoor and
outdoor units make. Learn to recognize and identify unusual
sounds that may signal the need for service.
• Keep Filter ('lean
A clogged or improperly installed air filter on your indoor unit
will increase operating costs and shorten the life of the unit. Plan
to inspect the filter monthly and clean or replace it as needed.
• Do Not Block Flora; 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 ('over 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 (13°C) On Cooling Mode
Your outdoor unit is not designed to operate when outdoor
temperatures are lower than 55W (13°C) without modification.
If operation below this temperature is required, consult your
Carrier dealer.
• Do Not Operate Above 66°F (19°C) on Heating Mode
Your outdoor unit is not designed to operate on heating mode
when outdoor temperatures are higher than 66 ° (19°C). You can
safely operate the system above 66 ° (19°C) on emergency or
auxiliary heat.
• Increase Heating Temperature 1-2 Degrees at a Time
During heating operation, increasing the thermostat setting more
than 2 degrees at a time may cause the supplemental heat source
to turn on. Needless use of supplemental heat can reduce
potential energy savings.
