GENERAL INFORMATION
This packaged air conditioner is designed only for outdoor ground
level installations and can be readily connected to the high static
duct system of a home. This unit is completely assembled, wired,
and run tested at the factory. The only connections needed
for installation are the supply and return ducts, line voltage,
thermostat wiring and the condensate drain.
This unit has been tested for capacity and efficiency in
accordance with AHRI standards and will provide many years
of safe and dependable comfort, providing it is properly installed
and maintained. Use of components other than those specified
may invalidate AHRI Certification, Code Agency Listing, and
limited warranty on the air conditioner.
Before You Install this Unit
√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.
√Check the electrical supply and verify the power supply is
adequate for unit operation. If there is any question concerning
the power supply, contact the local power company.
√All units are securely packed at the time of shipment and
upon arrival should be carefully inspected for damage prior
to installing the equipment at the job site. Verify coil fins are
straight. If necessary, comb fins to remove flattened or bent
fins. Claims for damage (apparent or concealed) should be
filed immediately with the carrier.
√Please consult your dealer for maintenance information
and availability of maintenance contracts. Please read all
instructions before installing the unit.
Locating the Air Conditioner
• Survey the job site to determine the best location for mounting
the outdoor unit. Select a solid, level position, preferably on
a concrete slab, slightly above the grade level, and parallel
to the home. If possible, select a site for the unit that is as
close as possible to the proposed return grille location. Unit
dimensions are shown in Figure 9 & Table 3, (page 11).

the air conditioner and its ducts in an area where they will be
shaded from the afternoon sun, when the heat load is greatest.
• The length of the supply and return ducts should be kept to
a minimum with no sharp radius bends.
• Consideration should also be given to availability of electric
power, service access, noise, and shade.
• Overhead obstructions, poorly ventilated areas, and areas
subject to accumulation of debris should be avoided. 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. See Figure 9 &
Table 3, (page 11) for unit dimensions.
Minimum Clearance Requirements
Sufficient clearance for unobstructed airflow through the outdoor
coil must be maintained in order to provide room for proper
servicing and achieve rated performance. However, 36” inches
from blower access panel, control access panel, and front panel is
highly recommended for servicing and maintenance. See Figure
1for minimum clearances to obstructions. DO NOT install unit in
a confined or recessed area that will allow discharge air from the
unit to re-circulate into the condenser air inlet, through the coil.

5. Tighten first screw and rotate collar clockwise so joint is near
3 o’clock position.
Return Duct
1. Assemble the collar by overlapping the two ends. NOTE: One
end of the collar is slotted and the opposite end has two small
holes. Position the end with small screw holes underneath
the slotted end.
2. Fasten the collar ends with two self drilling sheet metal screws.
3. Position the collar over the unit opening. Align the four holes
in the collar with the four dimples or holes (depending on unit
model) in the panel.
4. Secure the collar to the rear panel using self drilling screws
(10-16x.5).
Locating & Installing the Return Air Assembly
To simplify installation, locate and install the return air assembly
first. If desired, the return opening can be located inside a closet
with louvered doors that has an open area equal to or greater
than a 12” x 20” grille. 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 (Figure 4 (page 6)).
Verify the filter is readily accessible.
NOTE: The return air box with grille and filter 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.
• Duct work should be attached directly to the unit flanges for
horizontal applications.
• 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 flood back.
• The air conditioning output of the system will not cool
the home if air is lost to the outside through leaks in the
duct system. Ducts that are collapsed or restricted by
foreign objects will also prevent adequate air flow.
• All duct work passing through unconditioned space must
be properly insulated to minimize duct losses and prevent
condensation. Use insulation with an outer vapor barrier.
Refer to local codes for insulation material requirements.
AIR CONDITIONER INSTALLATION
Unpacking 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 and cause damage.
1. Remove the bands from around the unit.
2. Unfold the top and bottom cap flanges.
3. Carefully remove the top cap and tube.
Installing Return & Supply Air Collars (Optional)
If the supply and return collars are supplied with the unit, they
will be located in the supply duct. They can be easily positioned
over the supply and return ducts (Figure 3) and secured with
sheet metal screws. Return and supply duct opening sizes
are shown in Figure 9 & Table 3, (page 11). NOTE: Before
permanently installing the collars, it is recommended you pre-fit
them over the openings first to determine best fit and alignment.
Supply Duct
1. Position the supply duct collar so the edge of the unit opening
fits between the flange and the bead.
2. Overlap the collar ends keeping the small screw holes
underneath.
3. 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.

Figure 4. Return Air Box Assembly
1. Start the installation from under the home by cutting a small
hole in the subfloor. Determine how the floor joist location
will affect cutting the opening needed for the return air box.
NOTE: Floor joists are generally located on 16” centers,
leaving 14-3/8” between joists.
2. After measuring the return air box (approximately 12-1/4” x
20-1/4”), 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. NOTE: 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.
3. Set the box into the opening and fasten with screws or nails.
4. Install the filter and return air grille in the air box.
Locating & Installing the Supply Damper(s)
CAUTION:
If installing this air conditioning system in
conjunction with a furnace, a damper must be
installed in the furnace base assembly to prevent
cold air from 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.
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. See Figure
5 (page 6). The round supply opening in the slanted side
of the damper should face the side of the home where the air
conditioner is located.
1. Locate the center of the heat duct by cutting a small hole in
the fiberboard below the duct at the desired location.
2. Cut a hole approximately 3/4” larger than the damper opening
in the fiberboard.
3. 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.
4. Insert the damper into the duct and bend over all tabs flat on
the inside of the heat duct.
5. Seal the opening between the fiberboard and damper or
flexible duct.
Connecting the Return & Supply Air Flexible Ducts
• Flexible ducts can be connected to the corresponding fittings
with the clamps provided with the ducts. See Figure 9 & Table
3, (page 11). NOTE: To prevent a loss in cooling capacity,
make sure all connections are tight.
• 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.
• After the inner duct is connected to the proper fitting, the
insulation and plastic sleeve should be pulled over the
connection and clamped.
• Homes with multiple supply ducts (or 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:
For maximum performance, insulate the Y fitting.
Condensate Drainage
A 3/4” condensate fitting extends out of the side of the unit
(Figure 6). The drain trap, shipped in the electrical compartment,
must be installed to prevent water from collecting inside the unit.
1. Thread the elbow provided with the unit into the drain
connection until hand tight.
2. Connect the condensate tubing onto the fitting, forming a trap
near the drain connection.
3. Route the condensate tube from the trap to a suitable drain.
NOTE: For proper drainage, make sure the trap is level to
the ground and tubing outlet is below trap level.

3. For the temperature measured, determine the required liquid
refrigerant pressure from Table 4, (page 14), Table 5, (page
14), Table 6, (page 15), Table 7, (page 15), Table 8,
(page 16), &Table 9, (page 16) for 1.5, 2, 2.5, 3, 3.5, &
4 ton units. For 5 ton units see Figure 12 (page 17).
• If the pressure measured in step 1 is greater than the required
liquid refrigerant pressure determined in step 3, then there
is too much charge in the system. Remove refrigerant and
repeat steps 1 through 3 until the system is correctly charged.
• If the pressure measured in step 1 is less than the required
liquid refrigerant pressure determined in step 3, then there
is too little charge in the system. Add refrigerant and repeat
steps 1 through 3 until the system is correctly charged.
Safety switches
The high-pressure switch is factory-installed and located in the
liquid line internal to the unit. The switch is designed to protect
the system when very high pressures occur during abnormal
conditions. Under normal conditions, the switch is closed. If the
liquid pressure rises above 650 psig, the switch will open and
de-energize the unit. The switch will close again when the liquid
pressure decreases to 460 psig.
NOTE: When the switch opens and then closes, there will be
a 5 minute short cycling delay before the unit can energize.
AIR CONDITIONER MAINTENANCE
WARNING:
To prevent electrical shock, personal injury, or
death, disconnect all electrical power to the unit
before performing any maintenance or service.
The unit may have more than one electrical
supply.
Proper maintenance is important to achieve optimum
performance from the air conditioner. The ability to properly
perform maintenance on this equipment requires certain
mechanical skills and tools. If you do not possess these skills,
contact your dealer for maintenance. Consult your local dealer
about the availability of maintenance contracts.
Routine maintenance should include the following:
• Inspect and clean or replace air filters at the beginning of each
heating and cooling season, or more frequently if required.
• Inspect the condensate drain and outdoor coil at the beginning
of each cooling season. Remove any debris. Clean the outdoor
coil and louvers as necessary using a mild detergent and
water. Rinse thoroughly with water.
• Inspect the electrical connections for tightness at the beginning
of each heating and cooling season. Service as necessary.
CAUTION:
The unit should never be operated without a
filter in the return air system. Replace disposable
filters with the same type and size.
• Do not add additional oil to motors unequipped with oil tubes.
The compressor is hermetically sealed at the factory and does
not require lubrication.
3. Set the system mode to ON or COOL.
4. Set the temperature mode below room temperature. Verify
that the indoor blower, outdoor fan, and compressor energize
and the cooling function starts.
5. Verify the discharge air grilles are adjusted and the system
air is balanced.
6. Verify the duct work has no air leaks.
7. Verify the condensate drain is installed correctly and functions
properly.
8. Set the temperature mode above room temperature. The unit
should stop.
9. Instruct the homeowner on unit and thermostat operation and
filter servicing.
Air Circulation
Leave the thermostat system mode on OFF, and set the fan
mode to ON. Blower should run continuously. Check the air
delivery at the supply registers and adjust register openings for
balanced air distribution. Examine ducts for leaks or obstruction
if insufficient air is detected.
Set the thermostat fan mode to AUTO. The blower should stop
running.
System Cooling
Set the thermostat’s system mode to COOL and the fan mode
to AUTO. Lower the thermostat temperature selector below the
existing room temperature. Allow the cooling system to operate
for several minutes and check for the discharge of cool air at
the supply registers.
System Heating
(Available only when Electric heat is supplied) Set the thermostat’s
system mode to HEAT and the fan mode to either AUTO
(intermittent air) or to ON (continuous air). Raise the thermostat’s
temperature selector above the existing room temperature and
check the following:
1. The compressor and outdoor fan should not run.
2. The blower will run according to the thermostat’s fan mode
setting.
REFRIGERANT CHARGING
Charging the Unit
(with Outdoor Temperatures Above 65° F)
CAUTION:
This air conditioner contains liquid and gaseous
refrigerant under pressure. Adjustment of
refrigerant charge should only be attempted
by qualified, trained personnel thoroughly
familiar with the equipment and safe responsible
refrigerant handling procedures. Under no
circumstances should the homeowner attempt
to install and/or service this equipment. Failure
to comply with this warning could result in
equipment damage, personal injury, or death.
NOTE: The refrigerant charge can be checked and adjusted
through the service ports provided external to the unit. Use
only gage line sets which have a “Schrader” depression device
present to actuate the valve.
1. With the system operating at steady-state, measure the liquid
refrigerant pressure in psig at the service valve.
2. Measure the liquid refrigerant temperature (° F) at the service
valve.
