4.
Insert the wires of the power cable into the wire entry hole on the
side of the housing. By default the wire entry hole is nearest the
power wires on the PCB. If it is desired to have the power wires
enter from the other side, simply remove the plug installed in
the wire entry hole on the other side and place it in the default
location.
5.
Use a bushing approved for the type of cable/conduit used to
rigidly secure the cable/conduit to the housing of the ventilator
using 1/2" nominal fittings.
6.
Remove the wire nuts from the black (line), white (neutral)
and ground (green) power wires and connect each to the
corresponding wires in the electrical service. See
FIGURE 5
.
7.
If the ventilator will run continuously, replace the electrical
compartment cover, ventilator cover insulation, ventilator cover and
motor speed adjustment knob. If additional external controls will
be used to operate the unit intermittently, keep the cover off until
all wiring is completed.
8.
Do not restore electrical service until all ducting and control wiring
has been completed.
