This high efficiency Air Handling system has been precision engi-
neered, manufactured of high quality materials, and passed many rigor-
ous tests and inspections to ensure years of satisfactory service. 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 Air Handler is actually two units - the indoor air
blower and the indoor refrigeration coil, part of the outdoor AC or Heat
Pump system installed with this Air Handler. You may also have an
Electric Resistance Heater kit installed in this air handler.
_WARNING
FIRE OR ELECTRICAL HAZARD
Failure to follow the safety warnings exactly could result in serious
injury, death or property damage.
A fire or electrical hazard may result causing property damage, per-
sonal injury or loss of life.
SECTION h HOW YOUR AIR HANDLER
WORKS
If your hand is wet and you blow on it, it feels coot 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.
SECTION Ih SYSTEM OPERATION
Your thermostat puts full control of the comfort level in your home at
your fingertips. DO NOT switch your thermostat rapidly "On" and "Off"
or between "Heat" to "Cool" This could damage your equipment. Always
allow at least 5 minutes between changes.
SETTING THE THERMOSTAT
Although thermostats may vary widely in appearance, they are all
designed to perform the same basic function: to control the operation of
your air conditioning or heat pump system. Regardless of size or shape,
each thermostat wilI feature a temperature indicator; a dial, arm, or
push button for selection of the desired temperature; a fan switch to
choose the indoor fan operationl and a comfort switch for you to select
the system mode of operation.
Only approved thermostats have been tested and are fully compatible
with this equipment. Please be aware that many different thermostats
operate on batteries or "power stealing" principals. These types of ther-
mostats can not be supported as trouble free when used with this product.
A complete operating instruction is provided by the manufacturer for
each thermostat. Familiarize yourself with its proper operation to obtain
the maximum comfort with minimum energy consumption.
If your system has been designed to allow both cooling and heating
operation, you may have either a manual change-over type, or a pro-
grammable electronic type thermostat.
Manual change-over simply means that the comfort switch must be
manually positioned every time you wish to switch from the cooling to
heating or heating to cooling modes of operation.
The computerized electronic thermostat is actually a sophisticated elec-
tronic version of a manual change-over type. This thermostat includes
features which allow "set-back" temperature variations for periods of
sleep, or while you are away during the day, and means energy savings
for you. The thermostat also features a digital clock.
