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 operating at
its peak 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 unnec-
essary service calls, familiarize yourself with the following
facts:
Improper installation, adjustment, alteration, service, main-
tenance or use can cause explosion, fire, electrical 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 in-
staller or agency must use only factory authorized kits
or accessories when modifying this product.
• Your air conditioning system should never be operated with-
out a clean air filter properly installed. Plan to inspect the
filter periodically. A clogged air filter will increase operating
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 lessens the unit’s
efficiency and life span.
• Outdoor units must have unrestricted airflow. Do not cover
the unit, lean anything against it, or stand upon it. Do not
allow grass clippings, leaves, or other debris to accumulate
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 center
for your air conditioning system. You should familiarize your-
self with its proper operation. Attempting to control the sys-
tem 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 po-
tentially damaging to the compressor. Do not move the tem-
perature 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 com-
fort by running the fan continuously. ‘‘Air pockets’’ can form
due to the structure of the building, placement of registers,
et cetera. These air 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 ben-
efits 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 thermostat
and it maintains the indoor temperature at the level you se-
lect. Most thermostats for air conditioning systems have three
controls. These are the temperature control selector, FAN switch,
and SYSTEM switch.
The temperature control selector is a dial or lever that allows
you to establish the degree of temperature that you wish to
maintain for your personal comfort. Some thermostats pos-
sess two temperature control selectors: one for setting the
temperature desired during the cooling cycle, and one to set
the heating operation temperature (if the accessory 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 dur-
ing the time the air conditioner is operating. When the FAN
switch is set at the ON position, the blower will run con-
tinuously.
Typically, the SYSTEM switch on your thermostat offers the
following selections: COOL, OFF, and HEAT. Your thermo-
stat may also have a fourth selection, AUTO. The air con-
ditioner 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 operate when
the indoor temperature rises above the level that you wish to
maintain. With the SYSTEM switch set at the HEAT posi-
tion, 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 cool-
ing mode is activated when the indoor temperature rises above
the thermostat cooling temperature setting, or the heating mode
will be activated when the indoor temperature 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
