WARNING
• If mounting to Unistrut®, purchase model ACC 845. Model ACC 840 should be mounted to wood only . If the antivibration mount is altered in any way it may not be as effective, or effective at all, in controlling vibration. In
addition, be certain that no part of the system, including any extension column that might be used, comes in
contact with the vibrating surface. If mounting through a drop ceiling, be sure to cut a large enough hole in the
ceiling tile as to avoid contact with the extension column. If using an escutcheon ring, be sure it does not come
in contact with the false ceiling. Also be sure to use the rubber bumper (B) provided.

WARNING
• Tighten wood screws so that anti-vibration mount is
firmly attached, but do not overtighten. Overtightening
can damage the screws, greatly reducing their holding
power and decrease the anti-vibrational effectiveness!
• Tighten to 30-40 in • lb (3.4 - 4.5 N.M.) maximum
torque.
• Make sure that mounting screws are anchored into the
center of the joist. The use of an "edge to edge" stud
finder is highly recommended.
When attaching anti-vibration mount (A) to flush mount tube or extension column (both tube and column are
sold separately), tighten at least four complete turns ending with one of the small threaded holes aligned with
slot in the end of flush mount tube or extension column. Insert and tighten one M5 screw (H) to lock tube
position (shown below on right side). Note: For security the M5 phillips screw (H) can be replaced with
M5 socket-pin screws (G).
