SYSTEM
coil. These units are interconnected by
refrigerant tubes. (See Fig. 1.)
Each unit has a rating plate affixed to it
which provides necessary information
for specific identification of a unit. You
should familiarize yourself with the
product, model, and serial numbers listed
on each rating plate.
IMPORT ANT FA CTS
T o better protect your in vestment and to
eliminate unnecessary service calls,
familiarize yourself with the following
facts:
Listen To Your Unit
•
Your air conditioner has a scroll
compressor. Get to know the characteristic start-up and operational sounds.
Keep Filter Clean
•
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 operating costs and
shorten the life of the unit.
Do Not Block Registers
•
Supply-air and return-air registers
should not be blocked. Drapes, furniture, and toys are some of the items
commonly found obstructing registers.
Restricted airflow lessens the unit’s
efficiency and life span.
Do Not Cover or Block
•
Outdoor Unit
The outdoor unit must have unrestricted
airflow. Do not cover the unit, lean
anything against it, or stand on 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, etc.
®
Get To Know Your
•
Thermostat
Your multipurpose indoor thermostat is
the control center 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 rapidcycling, 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.
Continuous Fan
•
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 house,
placement of registers, etc. These air
pockets may be too cool or warm for
your liking. Continuous fan operation
minimizes any temperature differences.
Air Cleaners and Humidifiers
•
Systems equipped with electronic or
mechanical air cleaners and/or humidifiers offer the added benefits of ha ving the
air continuously cleaned year-round, and
humidified during the winter season.
Ventilation
•
A system equipped with a heat or
energy recovery ventilator offers the
advantage of exhausting stale air from
the home and allowing fresh air in from
the outdoors while minimizing heat loss.
Zoning
•
Your system may also be equipped
with a zoning system which allows
individual control ov er the temperatures
of separate areas of your home.
Identifying Your System
Take the time to get to know the type of
system you have. This will be helpful in
understanding the basic operation of your
new air conditioner.
The split-system type has an indoor and
an outdoor unit, each of which contains a

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 select. Most

thermostats have 3 controls: a temperature control selector, a FAN control, and
a SYSTEM or MODE control.
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 thermostats possess 2 temperature control
selectors: 1 for setting the temperature
desired during the cooling cycle, and
1 for setting the heating operation

The F AN control of fers 2 options for controlling the blower: A UTO 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 continuously—regardless of whether the cooling
or heating section is operating.
T ypically, the SYSTEM or MODE control
on your thermostat offers the follo wing
selections: COOL, OFF , and HEAT . Y our
thermostat may also have a fourth selection, AUTO. Neither the cooling or heating section will operate when the
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 SYSTEM or MODE control set to HEAT, the
heating section will operate automatically
when the indoor temperature falls below
the level that you ha v e selected.
The AUTO selection found on some
thermostats provides for automatic
changeover between cooling and heating
cycles. With the SYSTEM or MODE
control set to A UT O, 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.
Your thermostat may be PROGRAMMABLE or NON-PROGRAMMABLE.
A NON-PROGRAMMABLE thermostat does not allow the temperature settings to be varied throughout the day or
week without physically changing the
settings. A PR OGRAMMABLE thermostat 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,
F for heating.
then have the temperature return to
normal prior to waking up. The home’s
temperature can then be lowered again
during the day when no one is at home,
but again be at peak comfort level when
your family returns home. During the
summer, the opposite changes might be
programmed. When properly used, the
programming can result in energy savings on your home’ s heating and cooling.
COOLING CYCLE
When operating in the cooling cycle,
your air conditioner will run until the
indoor temperature is lowered to the le vel
you have selected. On e xtremely 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 and force your cooling unit
to work longer to keep your home
comfortable:
• 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
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 temperature is raised to the level you ha ve selected.
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.
Refer to your furnace User’ s Manual for
specific information on heating operation.
PERFORMING R OUTINE
MAINTENANCE
With the proper maintenance and care,
your air conditioning unit will operate
economically and dependably. Maintenance can be accomplished easily by
referring to the following directions.
Howev e r, before performing maintenance, consider these important safety
precautions:
• DISCONNECT ALL ELECTRICAL
POWER TO THE AIR CONDITIONER
BEFORE REMOVING ACCESS PANELS OR PERFORMING ANY MAIN-
TENANCE. Disconnect po wer to both the
indoor and outdoor units. NOTE: THERE
MAY BE MORE THAN 1 ELECTRICAL DISCONNECT SWITCH.
• ALTHOUGH SPECIAL CARE HAS
BEEN T AKEN T O MINIMIZE SHARP
EDGES IN THE CONSTR UCTION OF
YOUR UNIT , BE EXTREMELY CAREFUL WHEN HANDLING PARTS OR
REACHING INT O THE UNIT.
CHECK THE AIR FIL TER
A dirty air filter will cause excessi ve
strain on the compressor and blower
motor. This can cause the components to
overheat and automatically shut do wn. 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.
Disposable filters should be replaced by
similar, ne w filters of the same dimensions.
Reusable, permanent filters should be
washed in a solution of cold water
and mild detergent, then rinsed and
thoroughly dried. THE FILTER MUST
BE COMPLETELY DRY BEFORE
BEING REINSTALLED. To a v oid prolonged shutdown of your unit while a filter
is drying, you should have an e xtra filter
on hand. This would allo w you to rotate
between the 2 with minimal downtime for
your comfort system. Extra filters may be
purchased from your dealer .
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 fi lter location and
procedures for replacement or cleaning.
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

cover plate by sliding latches to w ard
center of plate. Lift filter to clear lower
flange. Filter is spring-loaded and will
“pop out”. Reinstall filter, being certain
to secure filter behind lower flange. When
reinstalling cover plate, secure plate
behind upper flange then slide tabs
outward.
The indoor fan coil unit may be located in
the attic. In this application, the filter could
be located behind the return air grille.
Access the filter by removing 2 scre ws
from return air grille.
ELECTRONIC AIR CLEANER
If your system contains an Electronic Air
Cleaner consult the User’ s Manual for
specific care of that product.
INDOOR COIL
If the indoor coil has only been operated
with a clean filter in place, it should
require minimal cleaning.
If coil cleaning is required, call your dealer
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.
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. Howe ve r ,
if the outdoor coil becomes dirty, use a
vacuum cleaner with soft brush attachment to clean the exterior surface. V acuum
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 dealer 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
yourself.
OUTDOOR COIL—
SEA COAST
If your unit is located near the ocean, special maintenance is required. Ocean mist/
breeze carries salt, which is corrosiv e to
most metals. Although your new unit is
made of galvanized metal and is protected
by top-grade paint, you should take the
precaution of additional maintenance
which consists of periodically washing the
unit. By washing all exposed surfaces and
coil approximately every 3 months, you
will be adding additional life to your unit.
Consult your installing contractor for
proper intervals/procedures for your
geographic area or service contract.
UNIT SUPPORT
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.
BEFORE YOU REQUEST
A “SER VICE CALL”
CHECK FOR THESE EASILY
SOLVED PROBLEMS:
• Check the indoor and outdoor disconnect switches. Verify that circuit
breakers are ON or that fuses hav e not
blown.
• Check for sufficient airflo w. 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.
• Check the settings on your indoor thermostat. 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 or A UT O.
If you require warmth, be sure the temperature control selector is set above room
temperature and the SYSTEM or MODE
control is set to HEAT or A UT O. The
F AN switch should be set to ON for
continuous blower operation or AUTO
if you wish blower to function only while
the unit is operating.
If your comfort system still fails to
operate, contact your servicing dealer
for troubleshooting and repairs. Specify
your apparent problem, and state the
model and serial numbers of your equipment. (Y ou should ha ve them recorded on
the last page of this booklet.) With this
information, your dealer may be able to
offer helpful suggestions ov er the phone or
save v aluable time through knowledgeable preparation for the service call.
REGULAR DEALER
MAINTENANCE
In addition to the routine maintenance
that you perform, your home comfort
system should be inspected regularly by
a properly trained service technician. The
inspection (preferably each year, but at
least every other year) should include the
following:
• Routine inspection of air filter(s).
Replacement or cleaning as required.
• Inspection and cleaning of the blower
wheel, housing, and motor .
• 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.
• A check of all electrical wiring and
connections.
• A check for secure physical connections of individual components within
units.
• Operational check of the air conditioning system to determine actual
working condition. Necessary repair
and/or adjustment should be performed
at this time.
Your servicing dealer may offer an
economical service contract that covers
seasonal inspections. Ask for further
details.
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.
