3. Safe Installation Requirements 4. Locating The Unit

The unit is designed for outdoor installation only. Place the unit on
a platform at ground level. The unit may be installed on a concrete

slab of 48" (1219mm) x 48" (1219mm) dimensions. Cement

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 procedures and equipped with the proper tools
and test instruments.

Failure to carefully read and follow all instructions in
this manual can result in unit malfunction, property
damage, personal 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 cus-

tomer to contact aqualified 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.

blocks on a 3" sand footing will also work. The slab or blocks
SHOULD NOT be in contact with any part of the structure. Check

local codes covering zoning, noise, platforms, etc..

If practical avoid locating next to fresh air intakes, vent or bed-

room windows. 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 of the 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 wil! be dis-

charged on unit (as from dryer vents.)

Clearances

Minimum clearances, as specified in FIGURE 1, MUST be main-
tained from adjacent structures to provide adequate air circula-

tion 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 allow addi-
tional clearance, especially around the condenser inlet and dis-

charge openings.

Do NOT install the unit in a recessed orconfined area that will per-

mit discharged air from the condenser to recirculate to the con-
denser inlet.

Installing Duct Collars

Duct collars are supplied with the unit and are attached to the sup-

ply and return openings with the flanges to the inside and must be
reversed before unit's installation.

1. Remove the screws from the collars and reverse them so
the flange is to the outside.

Installation

CAUTION

The unit must be installed with a slope no greater than 1/8"
per foot (lOmm per meter). For side to side leveling, the con-
densate drain side side MUST always be lower.

The unit MUST be situated in such away 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.

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 coi! blockage.

Platform MUST be high enough to allow for proper conden-

sate drainage.

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.

Condensate Drain

Ground Connections

The condensate drain outlet is a 3/4" (19.1 mm) threaded female

PVC connection located at the bottom of the 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 con-
densate from draining properly without a trap. To combat this neg-

ative pressure, a field supplied 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 if required by local
codes or if location of unit requires it. Run the drain line to an open

drain or other suitable disposal point.

Drain Line

A ground lug is installed on the control plate (or electric heat
mounting plate) for the ground connection. Use a copper conduc-

tor of the appropriate size from the unit to a grounded connection
in the electrical service panel orto a properly driven and electrical-

ly grounded ground rod. See warning on this page.

Line Voltage Wiring

Do NOT complete line voltage connections until unit is perma-

nently grounded. All line voltage connections and the ground con-
nection MUST be made with copper wire.

Connections for line voltage are made on the unit electrical con-
trol plate (see NO TAG). For access, remove the Blower/Electri-
cal access panel.

Refer to applicable wiring diagram in this Manual. Complete the

line service connections to the contactor 'L1, L2, L3' 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 Elec-

tric Heat Accessory section of this manual to determine line volt-
age connections. The Electric Heat Accessory 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 break-
er (if used) in the Electric Heat Accessory.

Converting 230V Units to 208V

To convert 230V units to 208V:

1. Turn electric power OFF

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 inthe United States with National
Electrical Code ANSI/NFPA 70-1990 (or current edition). Provide
line voltage power supply from a separate fused circuit with a dis-

connect switch (when required) located within sight of the unit.
Supply voltage, amperage, fuse and disconnect switch sizes

MUST conform with local codes and ordinances.

Wiring MUST be protected from possible mechanical damage
and MUST NOT interfere with removal of access panels, filters,

etc.

All exposed line voltage connections MUST be made through liq-
uid tight conduit to prevent water from entering the unit through

the electrical access..

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 blower / electrical access panel.

Low Voltage Wiring

For access, remove the electrical blower / electrical access panel.
Refer to the connection wiring diagram for the applicable model

and to the instructions included with the thermostat.

Route low voltage wires through the port located on the rear panel

and up to the control box.
NOTE: If an Electric Heat Accessory is installed, see the Electric

Heat Accessory Installation Section of this manual for low voltage

connections.

Thermostat Connections

The location of the thermostat has an important effect on the op-
eration of the unit. See the thermostat instructions for proper con-

nection. See NO TAG for Low Voltage Wire Harness
Connections

Field Installed Equipment

Wiring to be done in the field between the unit and other devices,
or between 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 instruc-
tions for the devices.

Final Electrical Check

Make a final wiring check to be sure system is correctly wired. In-
spect field installed wiring and the routing to ensure that rubbing

or chafing due to vibration will not occur.
NOTE: Wiring MUST be installed so it is protected from possible

mechanical damage.
