! WARNING
To prevent personal injury,
death, or property damage,
read and follow all instructions
and warnings, including labels
shipped with or attached to the
unit before operating your new
air conditioner.
SAFETY
CONSIDERATION
Recognize safety information. This is the
safety-alert symbol ! . When you see
this symbol on the unit or in instructions
and manuals, be alert to the potential for
personal injury.
Understand the signal word DANGER,
WARNING, or CAUTION. These words
are used with the safety-alert symbol.
DANGER identifies the most serious
hazards which will result in severe personal injury or death. WARNING signifies hazards that could result in personal
injury or death. CAUTION is used to
identify unsafe practices which would
result in minor personal injury or product
and property damage.
! WARNING
Improper installation, adjustment, alteration, service, maintenance or use can cause explosion, fire, electrical shock,
or other conditions which may
cause personal injury or property damage. Consult a qualified installer, service agency or
your distributor or branch for
information or assistance. The
qualified installer or agency
must use factory-authorized
kits or accessories when modifying this product.
YOUR COMFORT
SYSTEM
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 coil. These units are interconnected by
refrigerant tubes, as shown in Fig. 1.
Each unit has a rating plate affixed to
it. A rating plate 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.
Record them for future reference on the
last page of this booklet.
IMPORTANT FACTS
To better protect your investment and to
eliminate unnecessary service calls, familiarize yourself with the following facts:
•
Keep Filter Clean
Your air conditioning system should never
be operated without a clean air filter properly installed. Plan to inspect the filter
2
periodically. A clogged air filter will
increase operating costs and shorten the
life of the unit.
•
Do Not Block Registers
•
Do Not Cover or Block
Outdoor Unit
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
shortens its life span.
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
•
Continuous Fan
•
Air Cleaners and Humidifiers
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 damage
the unit.
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.

mechanical air cleaners and/or humidifiers offer the added benefits of having 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 over the temperatures of separate
areas of your home.
•
•
When Not To Use Your Unit
Do not operate your unit when outdoor
temperatures are below 55°F.
Check Condensate Drain
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.
Do not 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. Simply adjust the thermostat to
maintain the indoor temperature at the
level you select. Most thermostats have
three controls: a temperature control
selector, a FAN control, and a SYSTEM

or MODE control. Thermostats may vary
from those shown in Fig. 2 and 3.
MAIN
The temperature control selector can be a
dial, lever, or set of buttons that allows
you to establish the temperature that you
wish to maintain for your personal
comfort. Some thermostats possess
two temperature control selectors: one
for setting the temperature desired during
the cooling cycle, and one to set the heating operation temperature.
The FAN control offers two options for
controlling the indoor 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 continuously—regardless of
whether the cooling or heating section is
operating.
Typically, the SYSTEM or MODE control on your thermostat offers the following selections; COOL, OFF, AUTO and
HEAT. Neither the cooling nor 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 have 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 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.
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 PROGRAMMABLE 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, 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.
NOTE: Your 2-speed air conditioning
system has several special features built in
to protect the unit.
• 5-MINUTE TIME DELAY—Unit
will delay operation upon initial startup or short-cycling of the indoor
thermostat.
• 1-MINUTE TIME DELAY—When
changing speeds from low to high, or
high to low, there is a 1-minute time
delay. During the speed change delay,
the outdoor fan will continue to run.
• 2-MINUTE LOW-SPEED MINIMUM—If the unit has not operated
within the past 30 minutes, upon the
next cooling demand, it will operate for
a minimum of 2 minutes on low speed.
If you wish to program your accessory
electronic indoor thermostat, refer to
thermostat Installation Instructions.
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 conditioner will run for
longer periods at a time and have shorter
off periods than on moderate days. Your
2-speed air conditioner spends about
80% of its time operating in low speed.
This means that it will operate for longer
periods of time than a single-speed air
conditioner even on moderate days. This
longer operational time in low speed
results in higher efficiency operation,
lower operating noise, and better humidity control than a single-speed air conditioner could achieve.
4
The following conditions typically add
extra heat and/or humidity to your home
and make your cooling unit 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 have 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 Owner'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. Maintenance can be accomplished easily by
referring to the following directions.
However, before performing maintenance, consider these important safety
precautions below.
! WARNING
To prevent personal injury or
death disconnect all electrical
power to the air conditioner before removing access panels or
performing any maintenance.
Disconnect power to both the
indoor and outdoor units. Note:
there may be more than 1 electrical disconnect switch.
! CAUTION
Although special care has
been taken to minimize sharp
edges in the construction of
your unit, be extremely careful
when handling parts or reaching into the unit.
CHECK THE AIR FILTER
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, the components will fail and
need to be replaced. To avoid inefficient
operation or failure 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, new 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 avoid prolonged shutdown of your unit while a
filter is drying, you should have an extra
filter on hand. This would allow you to
switch between the two 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
Owner's Manual for filter location and
procedures for replacement or cleaning.
If your system includes an indoor fancoil unit, the filter is located in the unit
where it connects with the return-air duct
or plenum. (See Fig. 5.) Remove the
two black thumbscrews (or plastic pull
rings on modular fan coil), then pull out
the rack and filter. The clean filter must
be reinstalled with the cross-hatched
(when used) side facing the blower. With
the clean filter in place, secure the spring
tensioner, slide the tray into the unit, then
secure the thumbscrews.
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, which could
require removing the coil. Do not attempt
this yourself.
OUTDOOR COIL
If grass clippings, leaves, shrubbery, and
debris are kept away from the outdoor
unit, minimal care should 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 attachment to
clean the exterior surface. 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 dealer
for service. The outdoor fan motor may
have to be disconnected and the top panel
removed to gain access to the coil for
thorough 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 corrosive to
most metals. Although your new unit is
made out of galvanized metal and is protected by top-grade paint, you should
take the precaution of additional maintenance by periodically washing the unit.
By washing all exposed surfaces and coil
approximately every 3 months, you will
be adding life to your unit. Consult your
installing contractor for proper intervals/
procedures for your geographic area or
service contact.
UNIT SUPPORT
Your split-system outdoor unit should be
maintained at a level position. If its support shifts or settles 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 SERVICE CALL
CHECK FOR THESE EASILY
SOLVED PROBLEMS:
• Check the indoor and outdoor disconnect switches. Verify that circuit breakers
are on or that fuses have not blown.
• Check for sufficient airflow. Check the
air filter(s) for any accumulations of dirt.
Check for blocked return-air or supplyair 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 AUTO.
If you require heat, be sure the temperature control selector is set above room
temperature and the SYSTEM or MODE
control is set to HEAT or AUTO. The
FAN control should be set to ON for continuous blower operation or AUTO if you
wish blower to function only while the
unit is operating.

• Check note concerning special features
and time delays in “Operating Your Air
Conditioner” section.
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. (You should have them recorded on
the last page of this booklet.) With this
information, your dealer may be able to
offer helpful suggestions over the phone
or save valuable 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:
• 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
• Routine inspection of air filter(s).
Replacement or cleaning as required.
