3. Safe Installation Requirements 4. Locating The Unit
The unit is designed for outdoor installation only. Place the unit on a plat-
form at ground level. The unit may be installed on a concrete slab of 48"
Installation or repairs made by unqualified persons can result
in hazards to you and others. Installation MUST conform with
local building codes or, in the absence of local codes, with the
National Electrical Code NFPA70-1990 or current edition.
The information contained in this manual is intended for use
by a qualified service technician familiar with safety proce-
dures and equipped with the proper tools and test instru-
ments.
Failure to carefully read and follow all instructions in this
manual can result in unit malfunction, property damage, per-
sonal injury and/or death.
• Seal supply and return air ducts.
• Check to see that filters are installed correctly and are the proper
type and size.
NOTE: It is the personal responsibility and obligation of the customer to
contact a qualified installer to ensure that the installation is adequate and
conforms to governing codes and ordinances.
CAUTION
Do NOT operate unit in a corrosive atmosphere containing chlorine,
fluorine, or any other corrosive chemicals.
(1219mm) x 48" (1219mm) dimensions. Cement blocks on a 3" sand
footing will also work. The slab or blocks SHOULD NOT be in contact with
any part ofthe structure. Check local codes covering zoning, noise, plat-
forms, etc..
If practical avoid locating next to fresh air intakes, vent or bedroom win-
dows. Noise may carry into the openings and disturb people inside.
Avoid installations under roof overhangs without guttering. Water draining
from the roof onto the unit could produce excessive noise, and may cause
ice to build up on coil or fan.
Placement ofthe unit should be in a well drained area or the unit MUST be
supported high enough so runoff will not enter the unit.
Do not locate unit where heat, lint or exhaust fumes will be discharged on
unit (as from dryer vents.)
Clearances
Minimum clearances, as specified in FIGURE 1, MUST be maintained
from adjacent structures to provide adequate air circulation and room for
service personnel.
While minimum clearances are acceptable for safety reasons, they may
not allow adequate air circulation around the unit for proper operation.
Whenever possible, itis desirable to allowadditional clearance, especially
around the condenser inlet and discharge openings.
Do NOT install the unit in a recessed or confined area that will permit dis-
charged air from the condenser to recirculate to the condenser inlet.

Installing Duct Collars
Duct collars are supplied with the unit and are attached to the supply and
return openings with the flanges tothe inside and must be reversed before
unit's installation.

Installation
CAUTION
The unit must be installed with a slope no greater than 1/8" per foot
(10mm per meter), For side to side leveling, the condensate drain
side side MUST always be lower.
The unit MUST be situated in such a way as to provide safe access
for servicing.
The platform may be made of either concrete or pressure treated
wood and MUST be level and strong enough to support the unit's
weight.
1.Remove the screws from the collars and reverse them so the flange
is to the outside.
2.Make sure when pushing the collars into place that the "V" flange of
the collars seats into the supply and return holes securely.
3.Re-install screw in each collar so it goes through both of the holes in
the collar end. It does not matter how the ends of the collar overlap
in order to accomplish this.
FIGURE ;3 I Duct Collar Installation
Position platform separate from the building's foundation.
Install in a well-drained area, with the top surface of the platform
above grade level and above the average winter snow levels to
prevent coil blockage.
Platform MUST be high enough to allow for proper condensate
drainage.

Condensate Drain
The condensate drain outlet is a 3/4" (19.1 mm) threaded female PVC con-
nection located at the bottom ofthe unit to the left of the evaporator access
panel.
The circulating blower and the condenser fan create a negative pressure
on the condensate drain line that will prevent the condensate from drain-
ing properly without a trap. To combat this negative pressure, a field sup-
plied condensate trap that will allow a standing column of water of at least
2" (50.8mm) MUST be installed. The outlet of the trap must be at least 1"
below the unit drain connection. Install the trap as near to the unit as
possible for proper drainage.
A 3/4" (19.1 mm) drain line MUST be installed ifrequired by local codes or if
location of unit requires it. Run the drain line to an open drain or other suit-
able disposal point.

Drain Line
All exposed line voltage connections MUST be made through liquid tight
conduit to prevent water from entering the unit through the electrical ac-
cess..
Ground Connections
A ground lug is installed on the control plate (or electric heat mounting
plate) for the ground connection. Use a copper conductor of the appropri-
ate size from the unit to a grounded connection in the electrical service
panel or to a properly driven and electrically grounded ground rod. See
warning on this page.
Line Voltage Wiring
Do NOT complete line voltage connections until unit is permanently
grounded. All line voltage connections and the ground connection MUST
be made with copper wire.
Connections for line voltage are made on the unit electrical control plate
(see FIGURE 6). For access, remove the Blower/Electrical access panel.
Refer to applicable wiring diagram in this Manual. Complete the line ser-
vice connections to the contactor 'U terminals on the electrical control
plate. Check all screw terminals to ensure they are tight.
NOTE: If an Electric Heat Accessory is installed, refer to the Electric Heat
Accessory section of this manual to determine line voltage connections.
The Electric HeatAccessory mounts inside the unit in the heater box. Field
supplied line voltage wires for the Electric Heat Accessory (separate from
the field supplied line voltage wires to the unit) connect to the appropriate
circuit breaker (if used) in the Electric Heat Accessory.
* Condensate trap MUST be installed.
5. Unit Electrical Wiring
Electrical shock hazard.
Disconnect power at fuse box or service panel before making
any electrical connections.
Unit MUST be grounded to electrical service panel.
Failure to follow this warning can result in property damage,
personal injury, and/or death.
NOTE: All electrical work MUST conform with the requirements of local
codes and ordinances and in the United States with National Electrical
CodeANSI/NFPA 70-1990 (orcurrent edition). Providelinevoltage pow-
er supply from a separate fused circuit with a disconnect switch (when re-
quired) located within sight of the unit. Supply voltage, amperage, fuse
and disconnect switch sizes MUST conform with local codes and ordi-
nances.
Wiring MUST be protected from possible mechanical damage and MUST
NOT interfere with removal of access panels, filters, etc.
Converting 230V Units to 208V
To convert 230V units to 208V:
1.Turn electric power OFF.
2.Remove the blower/electrical access panel.
3. Locate the 24V control transformer.
4. Remove wire from the terminal labeled "240V" on the 24V control
transformer and reconnect it to the 208V terminal of the 24V control
transformer.
5. Replace the electrical/compressor access panel.
Low Voltage Wiring
For access, remove the electrical control/blower access panel.
Referto theconnectionwiringdiagramfor the applicablemodeland tothe
instructions included with the thermostat.
Route low voltage wires through the port located on the rear panel and up
to the control box.
NOTE: Ifan Electric Heat Accessory is installed, see the Electric Heat Ac-
cessory Installation Section of this manual for low voltage connections.
Thermostat Connections
The location of the thermostat has an important effect on the operation of
the unit. See the thermostat instructions for proper connection. See

Field Installed Equipment
Wiring to be done in the field between the unit and other devices, or be-
tween separate devices which are field installed and located, MUST NOT
exceed the temperature limitations for type T wire and MUST be installed
according to the manufacturer's instructions for the devices.
Final Electrical Check
Make a final wiring check to be sure system is correctly wired. Inspect field
installed wiring and the routing to ensure that rubbing or chafing due to
vibration will not occur.
NOTE: Wiring MUST be installed so itis protected from possible mechani-
cal damage.
