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 is what happens with an air conditioner. During the cooling cycle,
your system removes heat and humidity from your home and transfers
this heat to the outdoor air.
HEATING CYCLE (HEAT PUMPS)
During the heating cycle, your system removes heat and humidity from
the outdoor air and transfers 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 does not 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 min between changes.

CAUTION
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 must be used to turn the system OFF. Should the main
power be disconnected or interrupted for 8 h or longer,
do not
attempt to start the system for 8 h after the power is restored to the
outdoor unit. If heat is needed during this 8-h period, use emergency
heat.
