SECTION II: THERMOSTATS
YOUR KEY TO COMFORT
Congratulations . . .
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 thermo-
stat 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.
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 pur-
chase our system. Enjoy your comfort.
COOLING ONLY
If your air conditioning system is designed to provide cooling only (AC),
with no capability for heating operation (electric heat), a single-stage
cooling only thermostat, with a manual, one-position “Cool” and “Off”
comfort switch is all that is required for system operation.
The manufacturer recommends that the user read all sec-
tions of this manual and keep the manual for future refer-
ence.
NOTE: If you have an independent heating system (with a separate
thermostat), always be sure the heating control is turned “Off”
before turning on the cooling system.
SECTION I: SAFETY
COOLING AND HEATING
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.
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.
MANUAL CHANGE-OVER
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.

DON’T restrict air circulation. Placing furniture, rugs, etc. in such a way
that they interfere with air vents will make your system work harder to
achieve a comfortable temperature level. This requires more energy,
which means greater cost to you.
SERVICE CALLS
There are a few instances where the user can avoid unnecessary ser-
vice calls. If unit stops functioning properly check the following items
before calling your servicing dealer:
DON’T heat or cool when you are away. If you are going to be away for
a day or more, re-adjust your thermostat accordingly. Your furniture is
far less demanding than you are when it comes to comfort levels. How-
ever, don’t expect the system to restore comfort conditions immediately
upon returning home. It will take a little time.
1. Indoor section for dirty filter.
DON’T locate lamps or other heat-producing appliances (radios, TV’s,
heaters, etc.) near your thermostat. The heat from these items will give
your thermostat “false information” about the temperature in the room.
DO select a comfortable thermostat setting, but keep in mind that mod-
eration in temperature selection will save energy.
DO turn on your kitchen exhaust fan when cooking and your bathroom
exhaust fan when showering. Also, make sure your clothes dryer is
properly vented. If these items are neglected, an excess heat and
humidity condition may be created, causing your air conditioning sys-
tem to run longer.
2. Outdoor section for leaf or debris blockage. Eliminate problem,
turn off the thermostat for 10 seconds and attempt start. Wait 5
minutes. If system does not start, call your servicing dealer.
DO set your thermostat a few degrees lower than normal several hours
before entertaining a large group of people in a relatively small area.
People give off a considerable amount of heat and moisture in a closed
area.
FILTER CARE
These units are shipped without a filter and is the responsibility of the
installer to place a high velocity filter into the return air duct system.
DO keep drapes and venetian blinds closed when practical. These
items provide insulation against heat loss/gain.
Inspect the air filter(s) at least once a month. If they are dirty, wash
reusable filters with a mild detergent per manufacturer’s recommenda-
tions. Replace disposable filters with new filters. Install the clean filters
with “air flow” arrow in the same direction as the air flow in your duct.
Filters should be clean to assure maximum efficiency and adequate air
circulation.
DO contact a qualified service person to make repairs or adjustments to
your system. He has been trained to perform this service.

DON’T be a “thermostat jiggler”. Moving your thermostat setting will not
make your system heat or cool any faster. Adjust your thermostat to a
comfortable setting and leave it there.
