Congratulations . . .
On your purchase of one of the most versatile comfort conditioning systems available in the industry today. This 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 high efficiency air conditioning
system has been precision engineered, manufactured of high quality
materials, and has been passed many
rigorous 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 split system air conditioner 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 AIR
CONDITIONER 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 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.
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
System Off - On stand by: No heating,
cooling, or blower air. Set system
switch to “Off" and fan switch to “Auto".
Fan Only - 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 system
switch to “OFF” and the fan switch to
“ON”. Be sure to return the switches to
their original positions for normal operation.
Cooling - To operate the air conditioner, set system switch to “Cool", fan
switch to “Auto", and the temperature
selector lever to the desired temperature. For a cooler temperature, set
lever to lower number. For less cooling, set lever to higher number.
Heating - To operate the furnace for
heat, set system switch to “Heat", fan
switch to “Auto", and the temperature
selector lever to the desired temperature. For a higher temperature, set
lever to higher number. For a lower
temperature, set the lever to a lower
number.
Continuous Air Circulation - Regardless of whether heating or cooling the
home: Set fan switch to “On", system
switch to either “Heat" or “Cool" and
the temperature selector lever to the
desired temperature. This provides
continuous air filtering and more even
temperature distribution to all conditioned spaces. The sound level within
the home/building will also remain relatively constant.
To operate a Programmable/Electronic
thermostat: Refer to its User's Manual.
Set your thermostat for heating or for
cooling. Then set it for the desired temperature. Find the temperature that is
most comfortable for you, and then
leave your thermostat alone. Manu-
ally moving the thermostat up or
down to extreme settings will not
speedup temperature changes.
Avoid moving the thermostat up during heating - particularly where a
demand type electric meter is installed
and electric furnace is installed for
heating. This will increase your operating cost substantially.
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.
