WELCOME TO
EFFICIENT HOME
HEATING AND
COOLING COMFORT
Congratulations on your excellent
choice and sound investment in home
heating and cooling comfort!
Your new heat pump unit represents the
latest in engineering development and is
one of the best self-contained units
available today.
Your new unit is among the most
energy-efficient and reliable air
conditioning products available today.
To assure its dependability, spend just a
few minutes with this booklet now.
Learn about the operation of your heat
pump, and the small amount of
maintenance it takes to keep it operating
at its peak efficiency.
With minimal care, your new heat pump
will provide you and your family with
heating and cooling comfort—both now
and for years to come.
YOUR COMFORT
SYSTEM
Identifying Your System
Take the time to familiarize yourself
with the type of system you have. This
knowledge will be of use in
understanding the basic operation of
your new heat pump.
A self-contained unit has an indoor-air
and an outdoor-air coil, both contained
within a single cabinet. The unit also has
electric heat elements. (See Fig. 1.)
The unit has a rating plate affixed to the
lower right corner of the front panel
which provides necessary information
for specific identification of a unit. You
should familiarize yourself with the
product, model, and serial numbers
listed on the rating plate.
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. We
recommend changing the indoor-air
filter every month.
• Supply-air and return-air registers
should not be blocked. Drapes,
furniture, and toys are some of the
items commonly found obstructing
registers. Restricted airflow reduces
the unit’s efficiency and life span.
• For your new heat pump to function
properly, it MUST have a constant
outdoor-air supply. Outdoor air is
usually supplied through a grille in an
outside wall of the home. Make sure
this grille is NOT obstructed in any
way.
• Your multipurpose indoor thermostat
is the control center for your home
comfort 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.
• With some thermostats, increasing
the thermostat more than 2
°
during
heating mode may cause the
supplemental electric heaters to be
turned on to satisfy the thermostat.
Needless use of supplemental heat
reduces potential energy savings.
• You may find that you can maintain
greater personal comfort by operating
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, water should trickle
from the condensate drain of the
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. It is important
to make sure the condensate drain
tube is piped to an appropriate
location. Failure to do so can create a
high moisture problem, or excessive
defrosting may occur.
• On initial start-up of your new heat
pump, allow a minimum of 72 hr of
run time for mechanical wear in to
achieve peak performance. In the
summer, allow 24 hr for removal of
moisture.
• If you have installed a heat pump for
the first time, you should be aware of
certain operational characteristics that
are normal for all heat pumps. If you
have lived with an electric, gas, or oil
furnace in the past, you will notice that
your heat pump operates differently.
Air entering a conventional furnace at
60
°
F can be heated 60
°
to 100
°
F. This
would make the warm air exiting the
registers 120
°
to 160
°
F depending on
the system. Your heat pump warms that
same 60
°
F air 20
°
to 25
°
F. The warm
air exiting the registers is 80
°
to 85
°
F.
This air may feel cool because it is
slightly less than your body
temperature. However, it is sufficiently
warm to keep you comfortable and is
adding heat to your home. A heat pump
will run for much longer periods of
time than a conventional furnace. This
longer operational time is normal for
all heat pumps and is saving you
WARNING
Improper installation, adjustment,
alteration, service, maintenance,
or use can cause explosion, fire,
electrical shock, or other condi-
tions which may cause personal
injury or property damage. Con-
sult a qualified installer, service
agency, or your distributor or
branch for information or assis-
tance. The qualified installer or
agency must use factory-autho-
rized kits or accessories when
modifying this product.
WARNING
To prevent personal injury, death,
or property damage, read and fol-
low all instructions and warnings,
including labels shipped with or
attached to unit before operating
your new heat pump.
