WELCOME TO EFFICIENT
COOLING COMFORT
Congratulations on your excellent choice and sound invest­
ment in home cooling comfort!
Your new air conditioner represents both the latest in engi­
neering development and the culmination of many years of
experience from one of the most reputable manufacturers of
comfort systems.
Your new unit is among the most energy-efficient and reli­
able air conditioning products available today. To assure its
dependability, spend just a few minutes with this booklet
now. Learn about the operation of your air conditioner and
the small amount of maintenance it takes to keep it operat­
ing at its peeik efficiency.
With minimal care, your air conditioner will provide you and
your family with satisfying home comfort—both now and
for years to come.
IMPORTANT FACTS
To better protect your investment and to eliminate unneces­
sary service cedis, familiarize yourself with the following
facts:
A WARNING
Improper installation, adjustment, alteration, service,
mmntenance or use can cause explosion, fire, electriced
shock or other conditions which may cause personal
injury or property damage. Refer to this manual. For
assistance or additional information consult a qualified
installer,
service agency, distributor or branch. The
qualified installer or agency must use only factory
authorized kits or accessories when modifying this
product.
• Your air conditioning system should never be operated
without a clean air filter properly installed. Plan to inspect
the filter periodically. A clogged air filter will increase oper­
ating costs and shorten the life of the unit.
• Supply-air and return-air registers should not be
blocked. Drapes, furniture, and toys are some of the items
commonly found obstructing grilles. Restricted airflow less­
ens the unit’s efficiency and life span.
• Outdoor units must have unrestricted eiirflow. Do not
cover the unit, lean anything agmnst it, or stand upon it. Do
not allow grass clippings, leaves, or other debris to accumu­
late around or on top of the unit. Maintain a 12-in. minimum
clearance between the outdoor unit and tall grass, vines,
shrubs, et cetera.
• Your multipurpose indoor thermostat is the control cen­
ter for your air conditioning system. You should familiarize
yourself with its proper operation. Attempting to control
the system by other means—for instance, switching the
electrical supply power ON and OFF—may cause damage to
the unit.
• Thermostat “jiggling” causes rapid-cycling, which is
potentially damaging to the compressor. Do not move the
temperature selector on the thermostat for any reason for at
least 5 minutes after the compressor has shut off.
• You may find that you can maintain greater personal
comfort by running the fan continuously. “Air pockets” can
form due to the structure of the building, placement of reg­
isters, et cetera. These mr pockets may be too cool or warm
for your liking. Continuous fan operation minimizes any
temperature differences. Also, systems equipped with elec­
tronic air cleaners and/or humidifiers offer the added bene­
fits of having the air continuously cleaned year-round, and
humidified during the winter season.
• Your air conditioner will remove humidity from your
home during the cooling season. After a few minutes of
operation, you should be able to see water trickle from the
condensate drain of the cooling coil. Check this occasionally
to be sure the drain system is not clogged. Of course, don’t
expect to see much drainage if you live in a very dry
environment.
OPERATING YOUR AIR CONDITIONER
The operation of your air conditioning system is controlled
by the indoor thermostat. You simply adjust the thermo­
stat and it maintains the indoor temperature at the level
you select. Most thermostats for air conditioning systems
have three controls. These eu-e the temperature control selec­
tor, FAN switch, and SYSTEM switch.
The temperature control selector is a died or lever that
allows you to establish the degree of temperature that you
wish to mainteun for your personed comfort. Some thermo­
stats possess two temperature control selectors; one for set­
ting the temperature desired during the cooling cycle, and
one to set the heating operation temperature (if the acces­
sory electric heater is used). Typical settings are 78 degrees
Fahrenheit for cooling and 68 degrees for heating.
The FAN switch offers two options for controlling the
blower; AUTO and ON. When set to AUTO, the blower will
run during the time the air conditioner is operating. When
the FAN switch is set at the ON position, the blower will
run continuously.
Typically, the SYSTEM switch on your thermostat offers
the following selections: COOL, OFF, and HEAT. Your
thermostat may also have a fourth selection, AUTO. The eur
conditioner will not operate when the SYSTEM switch is
set at the OFF position. With the SYSTEM switch set at
COOL, the cooling section of your comfort system will oper­
ate when the indoor temperature rises above the level that
you wish to maintain. With the SYSTEM switch set at the
HEAT position, the accessory electric heater will operate
automatically whenever the indoor temperature falls below
the level that you have selected.
The AUTO selection found on some thermostats provides
for
automatic changeover between cooling and heating
cycles. With the SYSTEM switch set in the AUTO position,
the cooling mode is activated when the indoor temperature
rises above the thermostat cooling temperature setting, or
the heating mode will be activated when the indoor tempera­
ture drops below the thermostat setting for the heating
cycle.
COOLING CYCLE
When operating in the cooling cycle, your air conditioner
will run until the indoor temperature is lowered to the level
you have selected. On extremely hot days, your air condi­
tioner will run for longer periods at a time and have shorter
“off” periods than on moderate days.
The following are typical conditions that add extra heat
and/or humidity to your home. Your air conditioner will
work longer to keep your home comfortable under these
conditions:
• Entrance doors are frequently opened and closed
• Laundry appliances are being operated
• A shower is running
• More than the usual number of people are present in the
home
