IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary service calls, familiarize yourself with the following facts:
• Your heat pump system should never be operated without a clean air filter properly installed. Plan to inspect the filter periodically. A
clogged air filter will increase operating costs and shorten the life of the unit.
• Supply-air and return-air registers should not be blocked. Drapes, furniture, and toys are some of the items commonly found obstructing grilles. Restricted airflow lessens the unit’s efficiency and life span.
• The outdoor unit must have unrestricted airflow. Do not cover the unit, lean anything against it, or stand upon it. Do not allow grass
clippings, leaves, or other debris to accumulate around or on top of the unit. Maintain a 12-in. minimum clearance between the
outdoor unit and tall grass, vines, shrubs, etc.
• Your multipurpose indoor thermostat is the control center for your heat pump system. You should familiarize yourself with its proper
operation. Attempting to control the system by other means—for instance, switching the electrical supply power ON and OFF—may
cause damage to the unit.
• During heating, increasing the thermostat more than 2 degrees may cause the supplemental heaters to be turned on to satisfy the
thermostat. Needless use of the supplementary heat reduces potential energy savings.
• You may find that you can maintain greater personal comfort by running the fan continuously. Air pockets can form due to the structure
of the house, placement of registers, etc. These air pockets may be too cool or warm for your liking. Continuous fan operation minimizes
any temperature differences. Also, systems equipped with electronic air cleaners and/or humidifiers offer the added benefits of having the
air continuously cleaned year-round, and humidified during the winter season.
• Your heat pump will remove humidity from your home during the cooling season. After a few minutes of operation, you should be
able to see water trickle from the condensate drain of the indoor cooling coil. Check this occasionally to be sure the drain system is
not clogged. Of course, don’t expect to see much drainage if you live in a very dry environment.
NOTE TO INSTALLER: THIS MANUAL MUST BE LEFT WITH THE EQUIPMENT USER.

• During the heating cycle, air from your registers may seem cool. This is because the air is being delivered at a higher velocity and a
more constant flow than air supplied by a conventional furnace. Also, your heat pump supplies air at 90° to 105°F instead of in sudden
bursts of hot air as with a conventional furnace. The air may feel cool because it is slightly lower than your body temperature.
However, it is sufficiently warm to keep you comfortable.
• Ice or frost will tend to form on the outdoor coil during the winter heating operation. Your heat pump is designed to automatically
melt the ice. When in this defrost cycle, it is normal for steam or fog to rise from the outdoor unit. Do not be alarmed!
OPERATING YOUR HEAT PUMP
The operation of your heat pump system is controlled by the indoor thermostat. You simply adjust the thermostat and it maintains
the indoor temperature at the level you select. Refer to the thermostat operating instructions for information on how to operate your
thermostat.
COOLING CYCLE
When operating in the cooling mode, your heat pump will run until the indoor temperature is lowered to the level you have selected.
On extremely hot days, your heat pump will run for longer periods at a time and have shorter off periods than on moderate days.
Lowering the setpoint of your thermostat will not cause your heat pump to cool faster.
The following are typical conditions that add extra heat and/or humidity to your home. Your cooling unit will work longer to keep
your home comfortable under these conditions:
• Entrance doors are frequently opened and closed
• Laundry appliances are being operated
• A shower is running
• More than the usual number of people are present in the home
• More than the normal number of electric lights are in use
• Drapes are open on the sunny side of the home
HEATING CYCLE
With HEAT selected, the heating section of your home comfort system will operate until room temperature is raised to the level you
have selected. Of course, the heating unit will have to operate for longer periods to maintain a comfortable environment on cooler
days and nights than on moderate ones.
DEFROST CYCLE
When your heat pump is providing heat to your home and the outdoor temperature drops below 45°F, moisture may begin to freeze
on the surface of the outdoor coil. If allowed to build up, this ice would impede airflow across the coil and reduce the amount of heat
absorbed from the outside air. So, to maintain energy-efficient operation, your heat pump has an automatic defrost cycle.
The defrost cycle starts at a preset time interval of 90 minutes, although, it may be reset to either 30 or 60 minutes. Defrost will start
at the preset time only if the ice is sufficient to interfere with normal heating operation.
After the ice is melted from the outdoor coil, or after a maximum of 10 minutes in the defrost mode, the unit will automatically switch
back to normal heating operation.
Do not be alarmed if steam or fog appears at the outdoor unit during the defrost cycle. Water vapor from the melting ice may condense
into a mist in the cold outside air.
During certain weather conditions such as heavy snow and freezing rain it is not uncommon for ice to build up on the outdoor unit
grille. This is normal for these weather conditions. Do not attempt to remove the ice from the outdoor unit grille. This condition will
not affect the proper function of the unit and will clear within a few days.
EMERGENCY HEAT
The EMERGENCY HEAT setting on your thermostat refers to any supplementary heating appliance that may be included in your
home comfort system. Operation of the EMERGENCY HEAT source may be required if heating demands exceed the capacity of
the heat pump, or if the heat pump malfunctions.
During the heating season, switch to EMERGENCY HEAT if the electricity to your outdoor unit has been off for more than 30
minutes for any reason (i.e., power outage). Leave the switch in the EMERGENCY HEAT mode for an amount of time equal to that
during which the power was off. It isn’t necessary to exceed 12 hours. If you cannot determine how long the power has been off,
leave the switch in the EMERGENCY HEAT position for 8 hours.
NOTE:
The EMERGENCY HEAT switch is effective only when HEAT or AUTO is selected.
