If the box is being wired from the

INSIDE

of the appliance:

• Pull the electrical wires from outside the appliance through

this opening into the valve compartment.

• Loosen the two screws on the Romex connector, feed

the necessary length of wire through the connector and
tighten the screws.

• Make all necessary wire connections to the receptacle and

assemble the receptacle and cover to the junction box.

• Attach the junction box assembly to the inside of the

appliance with the two screws provided.

If the box is not wired at the time of appliance installation,
assemble the receptacle and cover to the box and install on
the inside of the appliance.

14-3 with ground Romex is the recommended wiring

to the appliance junction box. This allows the outlet

for the fan to be powered independently from other

accessories.
