Figure 13 - Relocating Junction Box Receptacle and
Electrical Supply Connection
A pre-wired junction box receptacle with strain relief is provided on the
right side of the cabinet for hard wiring the unit to a 15 Amp, 120VAC,
60Hz grounded branch circuit. If the installation demands that the
electrical supply be connected from the left side, the entire receptacle
box can be relocated to the left side by following these instructions:
Note: If you do not need to relocate the junction box, to connect the
electric supply follow steps 8 through 11 only:
1. Remove the 2 screws and outer cover with strain relief bushing
on the right side of the cabinet (see Figure 13).
2. Remove inner retaining screw on the junction box mounting tab.
3. Slide the junction box up until the screw mounting tab is lined
up to the notch in the outer cabinet.
4. Swing the junction box out and slip the retaining fl ange out
through the slot in the outer cabinet.
5. Remove the two screws and outer cover on the left side
of the outer cabinet.
6. Reinsert the junction box retaining fl ange through the slot now
on the left side and swing the screw mounting tab back through
the notch as before.
7. Slide the junction box down till the mounting tab holes line up
and replace the inner retaining screw.
8. With the junction box cover removed, pull the end of 3-wire
Romex supply line through the universal strain relief bushing
on the cover. (see Figure 13).
9. Strip back the outer Romex to about 4” and connect the black,
white and green wires accordingly using 3 wire nut connectors.
10. Tuck the tailing wires into the junction box and replace the
junction box cover using the 2 remaining screws.
11. Tighten the adjustment on the universal stran bushing to secure
the Romex sheathing and complete the supply connection.
CAUTION: label all wires prior to disconnection
when servicing controls. Wiring errors can cause
improper and dangerous operation. Verify proper
operation after servicing.
