Congratulations . . .
On your purchase of one of the most versatile heat pump systems available in the industry today. This Stealth series high efficiency system has been precision designed, manufactured of high quality materials and has passed many vigorous inspections
and tests to ensure years of satisfactory service.
This booklet is meant to increase your understanding of your system, tell you how to operate it efficiently and how to obtain
the greatest measure of comfort at the lowest operating expense. Please read this booklet thoroughly.
We appreciate your interest in our product and your decision to purchase our system. Enjoy your comfort.
This Heat Pump has been specially
developed and built as a heat pump to meet the dual needs of heating and
cooling. It's not just an air conditioner
with extra parts. That's why you can
rely on efficient, trouble-free operation.
Your system is fully automatic. Set the
thermostat and forget it. And it's automatically protected from damage by
voltage fluctuations or excessive heating or cooling demands.
Your split system heat pump consists
of two units - one installed outdoors
and one installed indoors. The indoor
unit may be installed in a basement,
attic, or crawl space.
HOW YOUR HEAT PUMP
WORKS
If your hand is wet and you blow on it,
it feels cool because some of the moisture is evaporating and becoming a
vapor. This process requires heat. The
heat is being taken from your hand, so
your hand feels cool.
That's what happens with a heat
pump. During the cooling cycle, your
system will remove heat and humidity
from your home and will transfer this
heat to the outdoor air.
During the heating cycle, your system
will remove heat and humidity from the
outdoor air and will transfer this heat to
your home. This is possible because
even 0°F outdoor air contains a great
deal of heat. Remember that your heat
pump doesn't generate much heat, it
merely transfers it from one place to
another
SYSTEM OPERATION
THERMOSTATS
Though thermostats may vary widely in
appearance they are all designed to
perform the same basic function, to
control the operation of your air conditioning system. Regardless of size or
shape, each thermostat will feature a
temperature indicator; a dial, arm or
push button for selection of the desired
temperature; a fan switch to choose
the indoor fan operation; and a comfort
switch for you to select the system
mode of operation.
Your new unit will require a three stage
heating / two stage cooling thermostat
for optimum efficiency and energy savings. Please be aware that many dif-
ferent thermostats operate on
batteries or “power stealing” principals. UPG can not support such
models to be trouble free when
used with this unit.
The following illustrations and discussion will aid you to determine which
type of thermostat you have for your
system.
A complete operating instruction is provided by the manufacturer for each
thermostat. Familiarize yourself with its
proper operation to obtain the maximum comfort with a minimum of
energy consumption.

FAN OPERATION SELECTION
A multi-position fan switch allows you
to choose the type of fan operation of
the indoor fan.
AUTO
With the thermostat fan switch set to
“AUTO”, the fan will run intermittently
as required for either heating or cooling. This position will provide the lowest operating cost. If you purchased
one of the recommended thermostats,
they have an Intelligent fan mode
which continually circulates the air during occupied modes or when you are
at home, and can cycle the fan during
unoccupied mode or during the night
while you sleep to further conserve
energy.
ON
CONTINUOUS FAN OPERATION:
With the thermostat fan switch set to
“ON”, the indoor fan will not shut off.
However, the cooling and heating systems will still operate as required by
room temperatures. This provides continuous air filtering and more even temperature distribution to all conditioned
spaces.
FAN ONLY OPERATION: On moderate days, usually during spring and fall,
when neither heating nor cooling is
required, you may want to run only the
fan to ventilate, circulate and filter the
air in your home or building. Set the
comfort control switch to “OFF” and the
fan switch to “ON”. Be sure to return
the switches to their original positions
for normal operation.
The Main power to the system must be kept “ON” at all
times to prevent damage to
the outdoor unit compressor.
If necessary, the thermostat
control switch should be used
to turn the system “OFF”.
Should the main power be
disconnected or interrupted
for 8 hours or longer, DO
NOT attempt to start the system for 8 hours after the
power has been restored to
the outdoor unit. If heat is
needed during this 8 hour
period, use emergency heat.
HEATING CYCLE
With the thermostat in the heating
position, and the outdoor temperature
in the range of 20 to 30° or below, the
outdoor unit will generally run 100% of
the time.
