IMPORTANT

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 effi ciently. Effi ciency 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, is cooled and dehumidi­fi ed. Then the cycle begins again.

fi lters and make any needed adjustments.

OPERATING INSTRUCTIONS

To Turn On Air Conditioner

If 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.

If 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 ex­ceeds the thermostat setting.

To Shut Off Air Conditioner

If 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.

If 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.

In addition, follow these simple rules:

1. Never run your system without fi lter. 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 fi lters 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
fi lters.

5. Keep your outdoor condenser coil clean.
You can hose it down when it gets dirty.

If your air conditioner isn’t working:

1. Make sure the fuses are not blown or that
your circuit breakers are on.

2. See that your thermostat is set at the desired
temperature and that your system’s switch
is on “Cool.”

3. For free air fl ow, make sure your return
register is not covered and that the fi lter is
clean.

4. Check the 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.

Inspecting Equipment: All units are securely
packed at the time of shipment and, upon arrival,
should be carefully inspected for damage. Claims
for damage (apparent or concealed) should be
fi led immediately with the carrier.

INSTALLATION

1. SELECT THE BEST LOCATION FOR THE
AIR COND ITIONING UNIT

IMPORTANT: DO NOT PLACE UNIT UNDER
THE HOME.

The single packaged air conditioners are de­signed 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 is completely
assembled, factory wired, and factory run tested.
The units are ready for easy and immediate
installation.

PRE-INSTALLATION CHECK

Before any installation is attempted, the cool­ing 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 recom­mendations contained in these instructions.
Consult local building codes and the National
Electrical Code (ANSI CI) for special installation
requirements.

• 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 confi ned space.

• If practical, place the air conditioner where it

and the ducts will be shaded from the after­noon 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 loca­tion.

• Keep in mind that the length of the supply and

return ducts should be kept to a minimum with
no sharp radiused bends.

2. UNPACK THE UNIT

It is recommended that the unit be unpacked
at the installation site to minimize damage due
to handling.

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 a few seconds.
Do this three or four times with fi ve
minutes between runs.

The electrical supply should be checked to de­termine if adequate power is available. If there

a. Remove the bands from around the unit.
b. Unfold the top and bottom cap fl anges.
c. Carefully remove the top cap and tube.

3. INSTALL THE RETURN AND SUPPLY AIR
FITTINGS ON THE UNIT

The supply and return fi ttings are included with
select models. If supplied, the duct fi ttings are
shipped in the supply duct. They attach to the unit
openings with a fl ange and bead arrangement,
secured with two sheet metal screws. Note: For
ease of access, install fi tting before positioning
unit in fi nal location.

SUPPLY DUCT

Position the supply duct collar, if supplied, so the
edge of the unit opening fi ts between the fl ange
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 fi tting. Re-tighten when instal­lation is complete.

Tap collar as necessary to ensure engagement
with unit opening and install second screw.
Tighten fi rst 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
collar over the opening and align the four notches
in the collar with the four dimples in the panel.
Using self-drilling screws (10-16x.5) attach the
collar to the rear panel.

4. LOCATING AND INSTALLING THE RE­TURN AIR ASSEMBLY

To avoid complications, locate and install the
return air assembly fi rst. The return air box
with grille and fi lter (Figure 4) should not be
located in heavy traffi c 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 louvered 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 fi lter box through a boxed-in area
at the closet fl oor level. Make sure the fi lter 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 fi ber under­board to determine how the fl oor 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 14­1/4”), cut the hole through the fl oor so that the
box will fi t between the fl oor joists. Care should
be taken when cutting through carpeting to avoid
snags. In most installations it will be necessary to
cut a similar hole in the fi berboard directly under
the hole in the fl oor. However, if the fl oor 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 fi lter and return air
grille in place.

5. LOCATING AND INSTALLING THE
SUPPLY DAMPER(S)

Figure 5. Supply Damper

CAUTION:

When a home is not equipped with a
make-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.

When installing this air conditioning
system in conjunction with a furnace,
a damper must be installed in the fur­nace base assembly to prevent cold
air being discharged around the heat
exchanger. Damage to the heat ex­changer 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.

DUCTING SYSTEM

DUCT REQUIREMENTS

The supply duct system, including the number
and type of registers, will have much more ef­fect on the performance of an air conditioning
system than any other factor. The duct must be
suffi ciently large to conduct an adequate amount
of air to each register.

THE AIR CONDITIONING OUTPUT OF THE
SYSTEM WILL NOT COOL THE HOME IF THE
AIR IS LOST TO THE OUTSIDE THROUGH
LEAKS IN THE DUCT SYSTEM. ALSO, DUCTS
WHICH ARE COLLAPSED OR RESTRICTED
BY FOREIGN OBJECTS WILL PREVENT
ADEQUATE AIR FLOW.

Note: For highly resistive duct systems it may be
necessary to add an additional return air duct and
or supply to achieve maximum performance and
prevent coil icing and refrigerant fl ood back.

When locating the supply damper(s), carefully
check fl oor joists and frame members that could
interfere with the installation of the damper or
fl exible 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,
fi rst cut a small hole in the fi berboard 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 fi berboard. Cut
a 9-1/8” x 13-1/8” hole in the duct and bend
over all tabs fl at on the inside of the heat duct.
After inserting the damper into the duct, bend

CONNECTING THE RETURN AND SUPPLY
AIR FLEXIBLE DUCTS

a. The supply duct for all units is twelve inches

in diameter. The return duct is 14” diameter
for all air conditioning units.

b. The fl exible ducts can be connected to the

corresponding fi ttings with the clamps pro­vided with the ducts. Note: All connections
should be leak tight or a loss in cooling
capacity will result.

c. The fl exible ducts may be cut to the required

length, see instructions packed with duct.
Keep all ducts as short and straight as pos­sible. Avoid sharp bends.

d. Ducts may be spliced with sheet metal

sleeves and clamps. (See Ducting Instal­lation Accessories below.)
