ABOUT YOUR HEAT PUMP SYSTEM

Identifying Your System
Your new Bryant heat pump system is what we call a ”split system.” It has an outdoor unit and an indoor unit connected to each other with copper tubing called refrigerant lines. Each of these units has a rating plate with the model and serial numbers you will need to reference when calling an authorized Bryant dealer about your system.
Take a few moments now to locate those numbers and record them in the spaces provided on the cover of this booklet.
USING YOUR NEW BRYANT SYSTEM
Your Bryant heat pump system is controlled by a wall–mounted Evolution Control installed inside your home. This system requires an Evolution Control which has software designed specifically to operate this system. See the Evolution Control Homeowner Guide for more details on system operation.

EVOLUTION EXTREME VARIABLE SPEED OPERATION

You may notice your system runs for longer periods of time. This system is designed to meet cooling or heating needs of the home at a wide range of conditions. Your indoor temperature will remain more consistent with fewer drafts, better humidity control, enhanced comfort and enhanced energy efficiency.
HEATING AND COOLING YOUR HOME
For heating or cooling operation, make sure the System or Mode control is set to the appropriate mode. Then, adjust the Temperature control to your desired setting. Finally, use the Fan control to select Automatic (turns on and off as heating is needed) or On (runs continuously).
Depending on your typical heating needs, your home comfort system may also include a supplementary heating source that will automatically turn on as needed. You may also select this heat source manually if desired.

OPERATION UNDER EXTREME CONDITIONS

Your heat pump will run as long as necessary to maintain the indoor temperature selected on your Evolution Control. On extremely hot days, your heat pump will run for longer periods at a time than on moderate days. Your system will also run for longer periods of time under the following conditions:

• Frequent opening of exterior doors
• Operating laundry appliances
• Taking hot showers
• More than the usual number of people present in the home
• More than the normal number of electric lights in use
• Drapes or blinds are open on the sunny side of the home

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

• During the heating cycle, your heat pump delivers a constant flow of air at around 95° to about 105° F, compared to sudden blasts of hot air provided by a typical furnace.
• 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. At the beginning and end of the defrost cycle, you may hear a “whoosh” sound coming from the unit. This is normal for heat pump applications.
• Heat pumps installed in areas expecting snow are elevated with support feet.

SOUND
Your new Evolution Extreme heat pump 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.
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.

• 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 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 Bryant 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 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.

• Level Installation
  Your Bryant 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 Bryant 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 Bryant 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 Evolution 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.
• Time delays – depending on the Bryant 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 Bryant Dealer for more information on time delays.

If you need to contact your Bryant 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 secondary 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.

Manufacturer reserves the right to discontinue, or change at any time
specifications or designs without notice and without incurring obligations.
