9. Route the electrical cable from the breaker/fuse
panel through the 7/8" (22mm) diameter hole and
secure to the cabinet using an approved clamp. The
power wires should extend approximately 6"
(152mm) into the control compartment.

has been turned off at the breaker/fuse panel of the
residence before proceeding.

wrapping it around the ground stud of the unit and
securing it using the #6-32 nut.
11. Using a wire nut, connect the hot lead (black), of
the power cable to the power cord wire that ends in
90° terminal (on the control board side, it ends on
your right hand side). Similarly, connect the neutral
wire (white), of the power cable to the power cord
ending with the straight terminal (on the control
board side, it ends on your left hand side) using a
wire nut. It is recommended that the wire nuts be
taped to the wires, using electrical tape, as an extra
safety measure.

compartment have been dislodged from the con-
trols. If they have, use the wiring diagram on the
unit or in the instruction manual to replace them in
their proper location.
13. Turn the power to the unit on at the breaker/fuse
panel. Place the unit into operation and check to
make sure that all of the systems are working prop-
erly.
