Installation to Wood Joist Ceilings
• Installer must verify that the supporting surface will safely support the combined load of the
equipment and all attached hardware and components.
• Tighten wood screws so that wall plate is fi rmly attached, but do not overtighten. Overtightening
can damage the screws, greatly reducing their holding power.
• Never tighten in excess of 80 in. • lb (9 N.M.).
• Make sure that mounting screws are anchored into the center of the stud. The use of an "edge to
edge" stud fi nder is highly recommended.
• Hardware provided is for attachment of mount through standard thickness drywall or plaster into
wood studs. Installers are responsible to provide hardware for other types of mounting situations
