3.Connect field installed copper ground wire(s) to the ground lug(s) on
the heater mounting plate. On models with more than one circuit, a
separate copper ground wire MUST be connected to a separate
ground lug for each circuit.
4. Route the field supplied line voltage wires for the heater to the line
side of the electric heat accessory's circuit breaker(s) or high voltage
wiring harness. Leave approximately 8" of excess wire so the break-
er or wiring harness may be moved to service. Make line voltage
connections to L3-L6 as appropriate. NOTE: If heaters without
breakers are used, route field wires to inside of unit and attach to
heater wires tagged L3-L6 as appropriate using supplied wire nuts.
6 Connect the red wire with terminal in the heater wire harness to the
loose red wire from the unit sequencer.
7. Connect the white wire from the heater wire harness to the white wire
from the thermostat at the field supplied low volt wire harness in the
control box.
8. Connect the grey and brown wires from the heater wire harness to
the blue wire from the unit 24V common. NOTE: If outdoor thermo-
stats are used for staging electric heat, connect the grey and brown
wires according to the thermostat instructions. See "Staging" in
Electrical Wiring Section of this Manual.
5. Connect the black wire with terminal from the heater wire harness to
the loose black wire at the unit blower.
NOTE: Check FIGURE 11 for heater/speed combinations that are
unacceptable.
After completing installation of the heater, install the breaker rain shield on
the blower access panel according to the following instructions on page
13. If using a pigtail style heater, proceed to Start-Up Procedures for Aux-
iliary Electric Strip Heat on page 14.
