WARNING! Risk of Shock! Label all wires prior to discon- nection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper opera- tion after servicing.
WARNING! Risk of Shock! Replace damaged wire with type 105º C rated wire. Wire must have high temperature insulation.
E. Junction Box Installation
If the box is being wired from the INSIDE of the appli- ance:
•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 12.2).
•Pull the electrical wires from outside the appliance through the opening into the valve compartment and secure wires with a Romex connector. See Figure 12.2.
•Make all necessary wire connections to the junction box/receptacle and reattach the junction box/receptacle to the outer shell.
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 12.3):
•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
•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.
