8.Using a slotted screwdriver, remove the 7/8" (22mm) diameter knockout from the right hand side of the cabinet above where the strain relief was located.

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.

WARNING: Make sure the power to the power cable has been turned off at the breaker/fuse panel of the residence before proceeding.

10.Connect the ground wire from the power cable by 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.

12.Visually check that none of the wires in the control 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.
