Read this owner information to become familiar with the capabilities and use
of your appliance. Keep this with literature on other appliances where you
have easy access to it in the future. If a problem occurs, check the instructions
and follow recommendations given. If these suggestions don't eliminate your
problem, call your installing contractor or distributor in your area.
INTRODUCTION
Most any air conditioner will keep you cool. Our air conditioner was designed to do
it efficiently. Efficiency means less cost to you while keeping you comfortable.
WHY YOUR AIR CONDITIONER WORKS SO WELL, SO QUIETLY
1. Air is cooled by a large evaporator coil. Moisture is also removed from the air by
this same coil.
2. Air is then delivered through the main duct, via registers, into your home.
3. Return air is drawn through the return register.
4. This air enters the unit, passes through the evaporator coil, iscooled and dehumidi-
fied. Then the cycle begins again.

OWNER iNFORMATiON
OPERATING iNSTRUCTiONS
ToTurn On Air Conditioner
ff you have a heating/cooling thermostat:
1. Set the system switch to "Cool."
2. Set the thermostat at the temperature level
you desire.
3. Turn the power on. Your air conditioner
should start as soon as room temperature
rises above the setting on the thermostat.
ff you have one thermostat for heating
and another for cooling, they must be
interlocked to prevent simultaneous
operation (See Figure 1):
1. Turn the heating thermostat to its lowest
possible setting.
2. If the cooling thermostat has an "On/Off"
switch, turn it "On."
3. Set the cooling thermostat to the desired
temperature.
4. Turn the power on. Your air conditioner
should start when room temperature ex-
ceeds the thermostat setting.
To Shut Off Air Conditioner
ff you have a heating/cooling thermostat:
1. Turn the system switch to "Heat" or "Off."
2. Turn the thermostat to the desired heating
temperature setting.
3. If you are turning your air conditioner off for
the winter or an extended period, shut off
the power to the air conditioner.
ff you have one thermostat for heating
and another for cooling, they must be
interlocked to prevent simultaneous
operation (See Figure 1):
1. Turn your cooling thermostat "Off" or to its
highest setting.
2. Turn the heating thermostat to the desired
temperature.
3. If you are turning your air conditioner off for
the winter or an extended period, shut off
the power to the air conditioner.
BEFORE YOU CALL ASERVICEMAN
Let your serviceman check your system at the
start of each air conditioning season. He will
make sure it's working right, clean or change
filters and make any needed adjustments.
In addition, follow these simple rules:
1. Never run your system without filter. If you
do, the cooling coils will get dirty and may
become clogged.
2. Set your thermostat at the comfort level you
wish -- and then leave it alone. Let it control
the operation of the air conditioning system.
If you get chilly, turn it up a degree at a time
until comfort is restored.
3. It takes longer for an air conditioner to cool
your dwelling than it does for your furnace
to heat it. So... don't turn the unit on and
expect a dramatic drop in temperature, at
least not right away. If your home is hot and
humid, the temperature will drop slowly.
4. Check your filters every ten days in summer
to see if they are dirty. To keep them clean,
use a mild solution of detergent and water
on washable types. Replace non washable
filters.
5. Keep your outdoor condenser coil clean.
You can hose it down when it gets dirty.
ff your air conditioner isn't working:
1. Make sure the fuses are not blown or that
your circuit breakers are on.
2. Seethatyourthermostatissetatthedesired
temperature and that your system's switch
is on "Cool."
3. For free air flow, make sure your return
register is not covered and that the filter is
clean.
4. Checkthe outdoor condenser coil and make
sure it is clean and not clogged with grass
or leaves.
If your air conditioner still isn't working, call your
nearest distributor.

GENERAL
Read the following instructions completely
before performing the installation.
These instructions are for the use of qualified
personnel specially trained and experienced
in the installation of this type of equipment
and related system components. Some states
require installation and service personnel to
be licensed. Unqualified individuals should not
attempt to interpret these instructions or install
this equipment.
The single packaged air conditioners are de-
signed for outdoor installation only and can be
readily connected into the high static duct system
of a home. The only connections needed for
installation are the supply and return ducts, the
line voltage, and thermostat wiring. A complete
air conditioning system typically consists of:
.Single Package Air Conditioner
.Home Fittings Kit
.Unit Fittings Kit
. Thermostat
The single package air conditioner iscompletely
assembled, factory wired, and factory run tested.
The units are ready for easy and immediate
installation.
Inspecting Equipment: All units are securely
packed at the time of shipment and, upon arrival,
shou Idbe carefully inspected for damage. Claims
for damage (apparent or concealed) should be
filed immediately with the carrier.
INSTALLATION
1. SELECTTHE BEST LOCATION FORTHE
AIR CONDITIONING UNIT
iMPORTANT: DO NOT PLACE UNiT UNDER
THE HOME.
, Select a solid, level position, preferably on a
concrete slab, slightly above the grade level,
and parallel to the home.
.The hot condenser air must be discharged
up and away from the home, and if possible,
in a direction with the prevailing wind.
Do not place the unit in a confined space.
. if practical, place the air conditioner where it
and the ducts will be shaded from the after-
noon sun when the heat load is greatest.
Try to select a site for the unit that is as close
as possible to the proposed return grille loca-
tion.
.Keep in mind that the length of the supply and
return ducts should be kept to a minimum with
no sharp radiused bends.
2. UNPACKTHE UNIT
It is recommended that the unit be unpacked
at the installation site to minimize damage due
to handEing.
PRE-INSTALLATION CHECK
Before any installation is attempted, the cool-
ing load of the area to be conditioned must be
calculated and a system of the proper capacity
selected. It is recommended that the area to
be conditioned be completely insulated and
vapor sealed.
The installer should comply with all local codes
and regulations which govern the installation
of this type of equipment. Local codes and
regulations take precedence over any recom-
mendations contained in these instructions.
Consult local building codes and the National
Electrical Code (ANSI CI) for special installation
requirements.
CAUTION:
Do not tip the unit on its side. Oil
may enter the compressor cylinders
and cause starting trouble, if unit has
been set on its side, restore to upright
position and do not run for several
hours.Then run unit for afew seconds.
Do this three or four times with five
minutes between runs.
a. Remove the bands from around the unit.
b. Unfold the top and bottom cap flanges.
c. Carefully remove the top cap and tube.
The electrical supply should be checked to de-
termine if adequate power is available. If there
is any question concerning the power supply,
contact the local power company.

Figure 3. Return and Supply Air Fittings
DUCT REQUIREMENTS
The supply duct system, including the number
and type of registers, will have much more ef-
fect on the performance of an air conditioning
system then any other factor. The duct must be
sufficiently large toconduct an adequate amount
of air to each register.
4. INSTALLTHE RETURN AND SUPPLYAIR
FITTINGS ON THE UNiT
The supply and return fittings are included with
select modeEs. If supplied, the duct fittings are
shipped in the supplyduct.They attach tothe unit
openings with a flange and bead arrangement,
secured with two sheet metal screws. Note: For
ease of access, install fitting before positioning
unit in final location.
SUPPLY DUCT
Position the supply duct collar, ifsupplied, so the
edge of the unit opening fits between the flange
and the bead. Overlap the collar ends keeping the
small screw holes underneath. Align the holes in
the crimped area and install one screw.
Note: It may be necessary to loosen the four
screws that hold the transition duct in order to
install the supply fitting. Re-tighten when instal-
lation is complete.
Tap collar as necessary to ensure engagement
with unit opening and install second screw.
Tighten first screw. Rotate collar clockwise so
joint is near three o'clock position.
RETURN DUCT
Align the 14" return duct slots with the holes in
the collar and install two screws. Position the

5. LOCATINGAND iNSTALLING THE RE-
TURN AIR ASSEMBLY
To avoid complications, locate and install the
return air assembly first. The return air box
with grille and filter (Figure 4) should not be
located in heavy traffic areas like hallways or
center of rooms. A good spot is in a corner or
under a table, if a minimum two inch clearance
is available. If desired, the return opening can
be located inside a closet with Iouvered doors
that have an open area equal to or greater than
the 12"x 20" grille furnished. The return air grille
can be placed in the wall of a closet and the air
ducted into the filter box through a boxed-in area
at the closet floor level. Make sure the filter is
readily accessible.
After determining the location of the return air
opening, start the installation from under the
home by cutting a small hole in the fiber under-
board to determine how the floor joist location
will affect cutting the opening needed for the box.
Floor joists generally are located on 16"centers,
leaving 14-3/8" between joists. After measuring
the return air box (approximately 12-1/4" x 14-
1/4"), cut the hole through the floor so that the
box will fit between the floor joists. Care should
be taken when cutting through carpeting to avoid
snags. In most installations itwill be necessary to
cut a similar hole in the fiberboard directly under
the hole in the floor. However, if the floor is more
than ten inches deep, it will only be necessary
to cut a hole for the collar on the return air box
or for the insulated duct.
Set the box into the opening and fasten with
screws or nails. Put the filter and return air
grille in place.
6. LOCATING AND iNSTALLING THE
SUPPLY DAMPER(S)
CAUTION:
When a home is not equipped with
amake-ready kit means must be
provided to prevent simultaneous
operation of the heating and cooling
units. A heat/cool thermostat is
available for this purpose.
REGISTER
/
AUTOMATIC DAMPER IS CLOSED
WHEN A/C UNiT iS OFF
Figure 5. Supply Damper
When installing this air conditioning
system in conjunction with a furnace,
adamper must be installed in the fur=
nace base assembly to prevent cold
air being discharged around the heat
exchanger. Damage to the heat ex=
changer and asphyxiation may occur
if a damper is not installed.
Check with the furnace manufacturer
for damper requirements. Failure to
install the required furnace damper
may invalidate code agency listing and
limited warranty on the furnace.
When locating the supply damper(s), carefully
check floor joists and frame members that could
interfere with the installation of the damper or
flexible duct. Ideally, the damper should be
located in the bottom of the main duct, forward
of center of the home, at least three feet from
the nearest register. The round supply opening
in the slanted side of the damper should face
the side of the home where the air conditioner
is located. To locate the center of the heat duct,
first cut a small hole in the fiberboard below the
duct at the desired location. After locating the
duct center, cut a hole approximately 3/4" larger
than the damper opening in the fiberboard. Cut
a 9-1/8" x 13-1/8" hole in the duct and bend
over all tabs flat on the inside of the heat duct.
After inserting the damper into the duct, bend
over all tabs flat on the inside of the heat duct.

CONNECTING THE RETURN AND SUPPLY
AIR FLEXIBLE DUCTS
a. The supply duct for all units is 12" in diam-
eter. The return duct is 14" diameter for all
air conditioning units.
b. The flexible ducts can be connected to the
corresponding fittings with the clamps pro-
vided with the ducts. Note: All connections
should be leak tight or a loss in cooling
capacity will result.
c. The flexible ducts may be cut to the required
length, see instructions packed with duct.
Keep all ducts as short and straight as pos-
sible. Avoid sharp bends.
d. Ducts may be spliced with sheet metal
sleeves and clamps. (See Ducting Instal-
lation Accessories page 6.)
e. Once the inner duct is connected to the
proper fitting, the insulation and plastic
sleeve should be pulled over the connection
and clamped.
f. For homes with multiple supply ducts or for
special applications, a Y fitting is available
to divide the supply air so it can be ducted
to different areas of the home for more ef-
ficient cooling. Note: TheY fitting should be
insulated for maximum performance.

Blower Speed -- For optimum system
performance and comfort, it may be necessary
to change the factory set speed. See figure 7 for
factory settings. To change the blower speed:
If Standard Motor (2, 2.5 and 3 Ton):
1. Disconnect all electrical power to the
unit and remove the service panel.
2. Place the desired blower speed lead on the
"COM" terminal. Use another wire tie (field
supplied) to bundle the remaining motor
leads.
If High Efficiency Motor (3.5, 4, and 5 Ton):
1. Disconnect all electrical power to the unit
and remove the blower panel.
2. Locate the orange and red wires terminated
to the blower motor. The orange wire controls
cooling operation while the red wire controls
heating operation.
3. Verify the required speed from the airflow
data found in figure 7. Place appropriate
wire on the appropriate motor speed tap for
the required airflow point.
Check all factory wiring per the unit wiring
diagram and inspect the factory wiring connec-
tions to be sure none loosened during shipping
or installation.
CAUTION'.
To avoid personal injury or property
damage, make certain that the motor
leads cannot come into contact with
any uninsulated metal components
of the unit.

Figure 9. Power Entry
CONDENSATE DRAIN
A 3/4" condensate fitting extends out of the side
ofthe unit.The drain trap, shipped in the electrical
compartment, must be installed to prevent water
from collecting inside the unit.Thread the elbow
provided with the unit into the drain connection
until hand tight. Install the trap into the fitting and
seal the joint. Make sure it is level. Route the
condensate from the trap to a suitable drain. Any
connecting tubing or hose must have the outlet
below the trap level for proper drainage.
WARNING:
Turn off electrical power before servic-
ing controls. Severe electrical shock
may result unless power is turned off.
Unit must be installed in compliance
with the National Electrical Code (NEC)
and local codes.
ELECTRICAL CONNECTIONS
1. ELECTRICAL SERVICE
High Voltage
a. Install a branch circuit disconnect of ad-
equate size per NEC. Locate the disconnect
within sight of the unit.
b. Extend leads through power wiring hole
provided. Connect L1 and L2 directly to the
contactor. (See Figure 9).
c. Ground the air conditioning unit using the
green grounding screw provided in the
control panel.
Low Voltage
a. Route 24vcontrol wires through the sealing
grommet near the power entrance.
b. Connect the control wires to the leads in
the low voltage area. (See Figure 10).
2. OVERCURRENT PROTECTION
In general, the best fuse or breaker for any air
conditioner is the smallest size that will permit
the equipment to run under normal use and
service without nuisance trips. Such a device,
sized properly, gives maximum equipment
protection. The principal reason for specifying
a time delay type is to prevent nuisance trips
when the unit starts.
In the event that a fuse does blow or a breaker
trips, always determine the reason. Do not arbi-
trarily put in a larger fuse or breaker and do not,
in any case, exceed the maximum size listed on
the data label of the unit.
3. LOCATING THE THERMOSTAT
Locate the thermostat away from drafts and
slamming doors and place itwhere there isa free
flow of air. Mount on an inside wall approximately
five feet from the floor.
Do not locate near a lamp, kitchen range, direct
sunlight, or in line with air flow from supply
registers.
a. Connect Cooling Thermostat: The cool-
ing thermostat available for use with this
system is equipped with a selector switch.
To shut down the air conditioner, set the
selector switch to the OFF position. Con-
nect the red and yellow wires from the unit
to the R and Y terminals respectively on
the thermostat subbase. Connect the green
wire to the yellow wire at the unit. See the
instruction sheet packed with the thermostat
for detailed methods of mounting.
Note: The cooling-only thermostat must be
connected to an interlock switch to prevent
simultaneous operation of the furnace and
the air conditioner. (See Figure 1, Page 2.)

an ON-AUTO fan switch which allows the
home owner to operate the indoor blower
when air circulation is desired.
Connect the red, yellow, green and brown
low voltage wires to the R or RC, Y, G and
W terminals respectively on the thermostat
base. The black wire is the 24 volt common
required on some thermostats. See ther-
mostat instruction sheet for more detailed
information.
Refer to furnace installation instructions
for required connections and proper heat
anticipator setting when installing unit with
an external furnace.
if two stage heating is desired, an
optional outdoor thermostat may be
installed: Connect the thermostat to the
orange low voltage wire and the W terminal
on the indoor thermostat base (See Figure
10). See the thermostat instructions for
details on setting the outdoor thermostat.
4. ELECTRIC HEAT PACKAGE (OPTIONAL)
The air conditioner is shipped without an auxil-
iary electric heat kit installed. If electric heat is
desired, an accessory Heater Kit must be field
installed. See Specifications Sheet for available
kits and their applications.
Select the correct size heat package for the
installation.
Follow installation instructions provided with
each heater kit.
Installation is most easily accomplished
before making duct or electrical connec-
tions.
The blower must be set to high speed for
electric heat operation.
