a. Remove the electrical box cover with a single screw.
b. Install the conduit tube into the conduit opening.
c. Secure all wires with the wiring support plate after the wires are installed through the wiring opening to
the electrical box.
d. Secure all wires with a cable band at the pipe cover to avoid contact with other wires that are in close
proximity to other components.
e. After all wiring is complete, exercise caution when installing the electrical box.
f. If there is a gap at the wiring opening cover any gaps near the insulation (3/16T x 1-15/16 inches x
7-7/8 inches (5T x 50 x 200mm), factory-supplied).
