SAFETY

HOW YOUR SYSTEM WORKS

COOLING CYCLE

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 an air conditioner. During the cooling cycle,
your system will remove heat and humidity from your home and will
transfer this heat to the outdoor air.

HEATING CYCLE (HEAT PUMPS)

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 pos-
sible 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

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

THERMOSTATS

YOUR KEY TO COMFORT

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 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.

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.

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.

This product must be installed and serviced by a qualified installer or
service agency. Improper installation, adjustment, alteration, service
or maintenance can cause injury or property damage.

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.
