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

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 dogged.
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. Ifyou 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 dght away. Ifyour 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.

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.

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 offfor
the winter or an extended period, shut off
the power to the air conditioner.

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

For free air flow, make sure your return
register is not covered and that the filter is
clean.
Check the outdoor condenser coil and
make sure it is clean and not clogged with
grass or leaves.

if your air conditioner still isn'tworking, call you r
nearest distributor.

If you have one thermostat for heating
and another for cooling, they must be
interlocked to prevent simultaneous
operation (See Figure I):
1.
2.
3.

Turn your cooling thermostat "Off" or to its
highest setting.
Turn the heating thermostat to the desired
temperature.
If you are turning your air conditioner off for
the winter or aM extended period, shut off
the power to the air conditioner.

BEFORE YOU CALL A SERVICEMAN
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.

THE AIR CONDITIONING UNIT

FOR

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 fi'om the home, and if possible,
in a direction with the prevailing wind.
• De not place the unit in a confined 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 unitthat is as close
as possible to the proposed return grille
location.
• Keep in mind that the length ofthe 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.

INSTALL THE RETURN AND SUPPLY
AIR FITTINGS ON THE UNIT
The supply and return fittings are included with
select models. If supplied, the duct fittings are
shipped in the supply duct. They attach to the
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

Positionthe supplyduct 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 installation is complete.
Tap collar as necessary to ensure engagement
with unit opening and install second screw.
Tighten first screw. Rotate collar clockwise so

LOCATING AND INSTALLING THE RETURN 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
underboard to determine hew 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. Careshould betakenwhen cuttingthrough
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 orforthe insulated
duct.
Set the box into the opening and fasten with
screws or nails. Put the filter and return air grille
in place.

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. Seal the
opening between the fiberboard and damper or
flexible duct.

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 sufficiently large to conduct an adequate
amount of air to each register.

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
ifa 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

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 below.)
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: The Y fitting should
be insulated for maximum performance.

A2 CAUTION:
To avoid personal injury or property
damage, make certain that the motor
leads cannot come into contact with
any uninsulated
the unit.

CONDENSATE DRAIN
A 3/4" condensate fitting extends out of the side
of the 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.

OVERCURRENT

PROTECTION

Connect the red, yellow, green and brown
tow 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 thermostat instruction sheet for more
detailed information.

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
arbitrarily 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

Do not locate near a lamp, kitchen range, direct
sunlight, or in line with air flow from supply
registers.
Connect Cooling Thermostat:
The
cooling 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.

Refer to furnace installationinstructionsfor
required connections and proper heat anticipator setting when installing unit with an
external furnace.

THE THERMOSTAT

Locate the thermostat away from drafts and
slamming doors and place it where there is a
free flow of air. Mount on an inside wall approximately five feet from the floor.

Connect the Heat-Cool Thermostat:
The heat-cool thermostat is equipped with
a system HEAT-COOL switch, which provides a positive means of preventing simultaneous operation of the heating and cooling units. The thermostat is also equipped
with an ON-AUTO fan switch which allows
the home owner to operate the indoor
blower when air circulation is desired.

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
