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.

humid, the temperature will drop slowly.
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.
Keep your outdoor condenser coil clean.
You can hose it down when it gets dirty.

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

iNFORMATiON

GENERAL
Read the following
before performing

instructions completely
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 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:

iMPORTANT:

,

DO NOT PLACE UNiT UNDER

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 location.
Keep in mind that the length of the supply and
return ducts should be kept to a minimum with
no sharp radiused bends.

UNPACKTHE

UNIT

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

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
vapor sealed.

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

INSTALLATION

insulated

and

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.
The electrical supply should be checked to determine if adequate power is available. If there
is any question concerning the power supply,
contact the local power company.

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 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.

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 then any other factor. The duct must be
sufficiently large to conduct an adequate amount
of air to each register.

CLEARANCES

Minimum clearances, as specified in Figure

small screw holes underneath. Align the holes in
the crimped area and install one screw.
Note: It may be necessary to loosen the four

if a damper is not installed.

After determining the location of the return air
opening, start the installation from under the
home by cutting a small hole in the fiber underboard 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 141/4"), 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 it will 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

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.

AND SUPPLY

The supply duct for all units is 12" in diameter. The return duct is 14" diameter for all
air conditioning units.
The flexible ducts can be connected

_ Elbow

to the

corresponding fittings with the clamps provided with the ducts. Note: All connections

should be leak tight or a loss in cooling
capacity will result.
The flexible 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.
Ducts may be spliced with sheet metal
sleeves and clamps. (See Ducting Installation Accessories page 6.)
Once the inner duct is connected to the
proper fitting, the insulation and plastic
sleeve should be pulled over the connection
and clamped.
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 efficient cooling. Note: TheY fitting should be
insulated for maximum performance.

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 connections to be sure none loosened during shipping

To avoid personal injury or property
damage, make certain that the motor

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

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.
