E. Junction Box Installation

The junction box must be wired from the INSIDE of the appliance:

Determine which side of the appliance the junction box is located on.

Pull the electrical wires from outside the appliance through the knockout making sure to use a Romex connector to fasten the electrical wires to the unit.

Pull enough wire into the valve compartment to easily reach the junction box location.

Remove the screw attaching the junction box to the junction box bracket and set it aside.

Route the wire through the knockout in the junction box bracket.

Wire the junction box and reattach it to the bracket by inserting the tab in the slot and attaching with screw previously removed. Ensure that a Romex connector is used to attach the electrical wires to the junction box.

F. Wall Switch Installation for Fan (Optional)

If the box is being wired to a wall mounted switch for use with a fan (See Figure 12.5):

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.
