sight from, the unit. Refer to the unit rating plate for maximum
fuse/circuit breaker size and minimum circuit amps (ampacity) for
wire sizing. See Tables 4 and 5 for electrical data.
The field-supplied disconnect switch box may be mounted on the
unit over the high-voltage inlet hole when the standard power and
low-voltage entry points are used. See Fig. 2 & 3 for acceptable
location.
See unit wiring label and Fig. 10 for reference when making high
voltage connections. Proceed as follows to complete the high-
voltage connections to the unit.
1. Run the high-voltage (L1, L2, L3) and ground leads into the
control box.
2. Connect ground lead to chassis ground connection.
3. Locate the black and yellow wires connected to the lines
side of the contactor.
4. Connect field L1 to black wire on connection 11 of the
compressor contactor.
5. Connect field wire L2 to yellow wire on connection 13 of
the compressor contactor.
6. Connect field wire L3 to Blue wire from compressor.

SPECIAL PROCEDURES FOR 208-V OPERATION
WARNING: Make sure that the power supply to the unit
is switched OFF and lockout tag installed before making
any wiring changes. Electrical shock can cause serious
injury or death.
C.
CONTROL VOLTAGE CONNECTIONS
NOTE: Do not use any type of power-stealing thermostat. Unit
control problems may result.
Use no. 18 American Wire Gage (AWG) color-coded, insulated
(35° C minimum) wires to make the control voltage connections
between the thermostat and the unit. If the thermostat is located
more than 100 ft. from the unit (as measured along the control
voltage wires), use no. 16 AWG color-coded, insulated (35° C
minimum) wires.
D.
STANDARD CONNECTION
Remove knockout hole located in the electric heat panel adjacent
to the control access panel. See Fig. 2 & 3. Remove the rubber
grommet from the installer’s packet (included with unit) and install
grommet in the knockout opening. Provide a drip loop before
running wire through panel.
Run the low-voltage leads from the thermostat, through the inlet
hole, and into unit low-voltage splice box.
Locate five 18-gage wires leaving control box. These low-voltage
connection leads can be identified by the colors red, green, yellow,
brown, and white (See Fig. 10). Ensure the leads are long enough
