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 unneces-
sary service calls, familiarize yourself with the following facts:
• 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 operat-
ing costs and shorten the life of the unit.
• Supply-air and return-air registers should not be blocked.
Drapes, fllrniture, and toys are some of the items com-
monly 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 accu-
mulate around or on top of the unit. Maintain a 12 in. mini
mum clearance between tire 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
system by other means for" instance, switching the elec-
trical supply power ON and OFF -- may cause damage to
the unit.
• Thermostat '_jiggling" causes rapid cycling, which is poten
tially damaging to the compressor. Do not move the tern
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 tile fan continuously. "Air pockets" can form
due to the structure of the building, placement of regis
ters, 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 fl'om your home
during tire cooling season. After a few minutes of opera
tion, you should be able to see water trickle from the
condensate drain of the cooling coil. Check this occasion-
ally to be sure the drain system is not clogged. Of course,
do not expect to see much drainage if you live in a very dry
environn]ent.
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 al
lows 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 tern
perature desired during the cooling cycle, and one to set tile
heating operation temperature (if tile accessory electric heater
is used). Typical settings are 78 degrees Fahrenheit for" cool-
ing and 68 degrees for heating.
The FAN switch offers two options for controlling tire 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 thermo-
stat may also have a fourth selection, AUTO. The air condi-
tioner 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 tire 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 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 temperature drops
below the thermostat setting for" the heating cycle.
I. COOLING CYCLE
When operating in the cooling cycle, your air conditioner will
run until tile indoor" temperature is lowered to the level you
have selected. On extremely hot days, your air conditioner
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
• More than the normal number of electric lights are in use
• Drapes are open on the sunny side of the home
