E. Junction Box Installation
If the box is being wired from the OUTSIDE of the appli-
ance:
•
Remove the cover plate located on the outer shell - right
side (see Figure 10.3).
•
Install the supplied Romex™ connector in the cover
plate.
•
Feed the necessary length of wire through the
connector.
•
Make all necessary wire connections and reattach the
cover plate to the outer shell.
If the box is being wired from the INSIDE of the appliance:
•
Remove the screw attaching the junction box/receptacle to
the outer shell, rotate the junction box inward to disengage
it from the outer shell (see Figure 10.3).
•
Pull the electrical wires from outside the appliance through
this opening into the valve compartment.
•
Feed the necessary length of wire through the
connector.
•
Make all necessary wire connections to the junction box/
receptacle and reassemble the junction box/receptacle to
the outer shell.
F. Wall Switch Installation for Fan (Op-
tional)
If the box is being wired to a wall mounted switch
for use with a fan (See Figure 10.4):
•
The power supply for the appliance must be
brought into a switch box.
•
The power can then be supplied from the switch
box to the appliance using a minimum of 14-3
with ground wire.
•
At the switch box connect the black (hot) wire
and red (switch leg) wire to the wall switch as
shown.
•
At the appliance connect the black (hot), white
(neutral) and green (ground) wires to the junction
box as shown.
•
Add a 1/4 in. insulated female connector to
the red (switch leg) wire, route it through the
knockout in the face of the junction box, and
connect to the top fan switch connector (1/4 in.
male) as shown.
