When Not To Use Your Unit
Do not operate your unit when outdoor
temperatures are below 55°F.

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.
The temperature control selector is a
button, lever, or set of buttons that
allows you to establish the degree of
temperature that you wish to maintain
for your personal comfort. Some ther-
mostats possess 2 temperature control
selectors: 1 for setting the temperature
desired during the cooling cycle, and
1 for setting the heating operation

COOLING CYCLE
CHECK THE AIR FILTER
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 conditioner will run for
longer periods at a time and have shorter
“off” periods than on moderate days.
A dirty air filter will cause excessive
strain on the compressor and blower
motor. This can cause the components to
overheat and automatically shut down. In
the extreme case, the components will
fail and need to be replaced. To avoid
inefficient or failed operation of your
unit, CHECK THE FILTER(S) EVERY
3 TO 4 WEEKS. Replace filter(s) when
necessary, or clean the filter(s) if you
have the reusable type.

temperature. Typical settings are 78°F
for cooling and 68°F for heating.
The FAN control offers 2 options for con-
trolling the blower:AUTO and ON.When
set to AUTO, the blower will run only
while the thermostat operates the cooling
or heating section. When the FAN control
is set to ON, the blower will run continu-
ously—regardless of whether the cooling
or heating section is operating.
The following are typical conditions
that add extra heat and/or humidity to
your home and force your cooling unit
to work longer to keep your home
comfortable:
Disposable filters should be replaced by
similar, new filters of the same dimensions.
• Entrance doors are frequently opened
and closed
Reusable, permanent filters should be
washed in a solution of cold water
• Laundry appliances are being operated
• A shower is running
Typically,theSYSTEMorMODEcontrol
on your thermostat offers the following
selections: COOL, OFF, and HEAT.Your
thermostat may also have a fourth selec-
tion, AUTO. Neither the cooling or heat-
ing section will operate when the

your comfort system. Extra filters may be
purchased from your dealer.

• More than the normal number of
electric lights are in use
SYSTEM or MODE control is set to OFF.
With the SYSTEM or MODE control set
to 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 SYS-
TEM or MODE control set to HEAT, the
heating section will operate automatically
when the indoor temperature falls below
the level that you have selected.
• Drapes are open on the sunny side of
the home
HEATING CYCLE
With the SYSTEM or MODE control of
your indoor thermostat set to HEAT, the
heating section of your home comfort
system will operate until room tempera-
tureisraisedtothelevelyouhaveselected.
Of course, the heating unit will have to
operate for longer periods to maintain a
comfortable environment on cooler days
and nights than on moderate ones.
There are no filters in the outdoor unit
of a split-system. If your indoor unit is a
gas or oil furnace, refer to your furnace
User’s Manual for filter location and
procedures for replacement or cleaning.
The AUTO selection found on some
thermostats provides for automatic
changeover between cooling and heating
cycles. With the SYSTEM or MODE
control set to AUTO, the cooling section
will operate when the indoor temperature
rises above the thermostat cooling
temperature setting, or the heating
section will operate when the indoor
temperature drops below the thermostat
setting for the heating cycle.
If your system includes an indoor fan coil
unit, the filter may be located in the unit
where it connects with the return-air duct
or plenum. (See Fig. 5.) Remove the filter
Refer to your furnace User’s Manual for
specific information on heating operation.
PERFORMING ROUTINE
MAINTENANCE
With the proper maintenance and care,
your air conditioning unit will operate
economically and dependably. Mainte-
nance can be accomplished easily by
referring to the following directions.
However, before performing mainte-
nance, consider these important safety
precautions:
Your thermostat may be PROGRAM-
MABLE or NON-PROGRAMMABLE.
A NON-PROGRAMMABLE thermo-
stat does not allow the temperature set-
tings to be varied throughout the day or
week without physically changing the
settings.A PROGRAMMABLE thermo-
stat allows various daily temperature
changes to be preset. During the winter,
for example, you may wish to “set back”
the temperature of your home at night,

system should be inspected regularly by
aproperlytrainedservicetechnician.The
inspection (preferably each year, but at
least every other year) should include the
following:
UNIT SUPPORT
• Routine inspection of air filter(s).
Replacement or cleaning as required.
Your split-system outdoor unit should be
maintained in a level position. If its
support should shift or settle so that the
unit is no longer level, you should correct
the condition. Relevel it promptly to
assure that water drains out of the unit. If
you notice that water or ice collects
beneath the unit, arrange for it to be
drained away from the unit.
• Inspection and cleaning of the blower
wheel, housing, and motor.
The indoor fan coil unit may be located in
theattic. Inthisapplication, thefiltercould
be located behind the return air grille.
Access the filter by removing 2 screws
from return air grille.
• Inspection and, if required, cleaning of
indoor and outdoor coils.
• Inspection of the indoor coil drain pan,
plus the primary and secondary drain
lines. If supplied, the auxiliary drain pan
and line should be inspected at this time.
Service should include cleaning if
required.
ELECTRONIC AIR CLEANER
If your system contains an ElectronicAir
Cleaner consult the User’s Manual for
specific care of that product.
BEFOREYOU REQUEST
A“SERVICE CALL”
• A check of all electrical wiring and
connections.
INDOOR COIL
If the indoor coil has only been operated
with a clean filter in place, it should
require minimal cleaning.
CHECK FOR THESE EASILY
SOLVED PROBLEMS:
• Check the indoor and outdoor dis-
connect switches. Verify that circuit
breakers are ON or that fuses have not
blown.
• A check for secure physical connec-
tions of individual components within
units.
Ifcoilcleaningisrequired, callyourdealer
for service. It may be necessary to clean
the coil with a detergent solution and rinse
it with water. This could require the
removal of the coil.You should not
attempt this yourself.
• Operational check of the air condi-
tioning system to determine actual
working condition. Necessary repair
and/or adjustment should be performed
at this time.
• Check for sufficient airflow. Check
the air filter(s) for any accumulations of
dirt. Check for blocked return-air or
supply-air registers. Be sure registers are
open and unobstructed.
Your servicing dealer may offer an
economical service contract that covers
seasonal inspections. Ask for further
details.
OUTDOOR COIL
If grass clippings, leaves, shrubbery, and
debris are kept away from the outdoor
unit, minimal care should be sufficient to
keep the system functioning properly. For
proper drainage, debris must be removed
periodically from the base pan. However,
if the outdoor coil becomes dirty, use a
vacuum cleaner with soft brush attach-
menttocleantheexteriorsurface.Vacuum
coil surface using an up and down motion.
Be careful not to bend or damage coil fins.
If dirt is deep in the coil, contact your deal-
er for service. The outdoor fan motor may
have to be disconnected and the top panel
removed to gain access to the coil for thor-
ough cleaning. Do not attempt this
• Check the settings on your indoor ther-
mostat. If you desire cooling, see that the
temperature control selector is set below
room temperature and the SYSTEM or
MODE control is set to COOL orAUTO.
If you require warmth, be sure the temper-
ature control selector is set above room
temperature and the SYSTEM or MODE
control is set to HEAT or AUTO. The
FAN switch should be set to ON for
continuous blower operation or AUTO
if you wish blower to function only while
the unit is operating.
FOR THE RECORD
Record the model, product, and serial
numbers of your new equipment in
the spaces provided. This information,
along with the other ready-reference
facts requested, will be necessary
should you ever require information or
service.
If your comfort system still fails to
operate, contact your servicing dealer
for troubleshooting and repairs. Specify
your apparent problem, and state the
