WELCOME TO EFFICIENT YEAR-ROUND COMFORT
Congratulations on your excellent choice and sound invest-
ment in home comfort! Your new dual fuel heat pump repre-
sents both the latest in engineering development and the
culmination of many years of experience from one of the most
reputable manufacturers of comfort systems. Your new unit
is among the most reliable home comfort products available
today. To assure its dependability, spend just a few minutes
with this booklet now. Learn about the operation of your dual
fuel heat pump and the small amount of maintenance it takes
to keep it operating at its peak efficiency.
With minimal care, your dual fuel heat pump will provide
you and your family with dependable home comfort — both
now and for years to come.
IMPORTANT FACTS
To better protect your investment and to eliminate unneces-
sary service calls, familiarize yourself with the following facts:
WARNING: Improper installation, adjustment, alter-
ation, service, maintenance, or use can cause explo-
sion, fire, electrical shock, or other conditions which may
cause personal injury or property damage. Refer to this
manual. For assistance or additional information con-
sult a qualified installer, service agency, distributor, or
branch office. The qualified installer or agency must use
only factory authorized kits or accessories when modi-
fying this product.
• Your dual fuel heat pump system should never be oper-
ated without a clean air filter properly installed. Plan to in-
spect 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.
• Outdoor units 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-inch minimum
clearance between the outdoor unit and tall grass, vines, shrubs,
et cetera.
• Your multipurpose indoor thermostat is the control center
for your dual fuel heat pump system. You should familiarize
yourself with its proper operation. Attempting to control the
system by other means — for instance, switching the electri-
cal supply power ON and OFF — may cause damage to the
unit.
• Thermostat ‘‘jiggling’’ causes rapid-cycling, which is poten-
tially damaging to the compressor. Do not move the tempera-
ture selector on the thermostat for any reason for at least
5 minutes after the compressor has shut off.
• You may find that you can maintain greater personal com-
fort by running the fan continuously. ‘‘Air pockets’’ can form
due to the structure of the building, placement of registers,
et cetera. 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 clean-
ers and/or humidifiers offer the added benefits of having the
air continuously cleaned year-round, and humidified during
the winter season.
• Your dual fuel heat pump will remove humidity from your
home during the cooling season. After a few minutes of op-
eration, you should be able to see water trickle from the con-
densate drain. Check this occasionally to be sure the drain
system is not clogged. Of course, don’t expect to see much drain-
age if you live in a very dry climate.
OPERATING YOUR DUAL FUEL HEAT PUMP
The operation of your dual fuel heat pump is controlled by
the indoor thermostat. You simply adjust the thermostat and
it maintains the indoor temperature at the level you select.
Most thermostats for dual fuel heat pump systems include
temperature control selector, FAN switch, and SYSTEM switch.
EMERGENCY HEAT (EM HEAT) setting is provided with
the SYSTEM switch. See Fig. 1.
The temperature control selector is a dial or lever that al-
lows you to establish the temperature that you wish to main-
tain for your personal comfort. Some thermostats possess two
temperature control selectors: one for setting the tempera-
ture desired during the cooling cycle, and one to set the heat-
ing operation temperature. Typical settings are 78 degrees
Fahrenheit for cooling and 68 degrees for heating.
The FAN switch offers two options for controlling the blower:
AUTO and ON. When set to AUTO, the blower will run dur-
ing the time the dual fuel heat pump is operating. When the
FAN switch is set at the ON position, the blower will run con-
tinuously.
Typically, the SYSTEM switch on your thermostat offers the
following selections: COOL, OFF, HEAT, and EMERGENCY
HEAT. Your thermostat may also have a another selection,
AUTO. The dual fuel heat pump will not operate when the
SYSTEM switch is set at the OFF position. With the SYS-
TEM switch set at COOL, your heat pump will operate in its
cooling mode when the indoor temperature rises above the
level that you wish to maintain. With the SYSTEM switch
set at the HEAT position, your dual fuel heat pump will pro-
vide warmth whenever the indoor temperature falls below the
level that you have selected.
The AUTO selection found on some thermostats provides for
automatic changeover between cooling and heating cycles. With
the SYSTEM switch set in the AUTO position, the cooling
mode is activated when the indoor temperature rises above
the thermostat cooling temperature setting, or the heating
mode will be activated when the indoor temperature drops
below the thermostat setting for the heating cycle.
