[. . . ] Consult with an architect or building engineer regarding wall strength. These instructions are intended for use on preconstruction installations. This unit can be installed in an existing finished wall but will require additional drywall finish work and extra effort so as to minimize the drywall finish work needed. Use extreme caution when installing the unit post-construction so that no one cuts into existing electric wires, gas lines, water lines or other utilities hidden by the finished wall. Serious personal injury could occur. Required Tools: 1/2" wrench Drill motor Drill bits Saw Carpenter level Procedure 1. Remove contents from carton and examine for damaged or missing parts. 2.

Suggestion: a junction box will fit horizontally above the ½" conduit knockouts or vertically in the lower half of the Wall Box. 7. Place the Wall Box into the opening such that the Four Screw Studs in a row are near the top and that the back of the Wall Box is flush with the backside of the 2x4.

Fasten the Wall Box to the wood stud frame using 3/8" diameter lag screws (not included).
