IMPORTANT FACTS ABOUT HEAT PUMP SYSTEMS

Heat pump systems have a few unique features and operations that you should be aware of:

SDuring 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￿ to about 105￿ F, 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.

SIce 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.

SHeat 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:

SListen 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.

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. Plan to inspect the filter monthly and clean or replace it as needed.

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” 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 On Cooling Mode

Your outdoor unit is not designed to operate when outdoor temperatures are lower than 55_F without modification. If operation below this temperature is required, consult your Bryant dealer.

A complete Evolutionr System with low ambient temperature cooling capability can operate down to 0_F outside temperature when properly set up.

SDo Not Operate Above 66_ F on Heating Mode

Your outdoor unit is not designed to operate on heating mode when outdoor temperatures are higher than 66_F. You can safely operate the system above 66_F on emergency or auxiliary heat.

SIncrease 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.
