W. For safety, all wiring of the electrical boxes and accessories should be completed after the plate is fully installed and secure.

9.Place the mounting plate back over T-bar rails, so that the hole in the tile aligns with the pipe adapter plate. If necessary, loosen the lock nuts on the pipe adapter plate and readjust the plate to align over the hole. If you wish to fit the anti-vibration pads, follow step 10 below. If not, just tighten down the lock nuts and proceed to step 13.

NDO NOT rest, or lean on the mounting plate or suspended ceiling grid when attaching turnbuckles, tie wire, or drilling into ceiling.

10.To mount the four optional self adhesive anti-vibration pads, completely unscrew the lock nuts on the adapter plate, and remove the top section only.

11.Peel and attach the pads to the underside of the adapter plate, one near each corner (see figure 3).

12.Replace top adapter plate and secure in place with locking nuts.

13.Attach the four turnbuckles to the long sides of the mounting plate, one near each corner (see figure 2).

Securing the mounting plate to the structural ceiling

Follow the steps below, according to the structural ceiling type, and preferred method.

Concrete ceilings

1.Mark and drill four holes, at least 1½" (38 mm) deep, into the ceiling, using a ¼" (6 mm) diameter carbide tipped drill bit.

NThese holes should not be drilled directly above where the turnbuckles attach, but offset about 10 degrees out from vertical (see figure 2).

2.Tap the concrete anchors into the drilled holes, until the head is seated against the ceiling material.

3.Using the claw on the hammer or a pair of pliers, pull down firmly on each of the anchors. This will set and secure the anchors in place.

Wooden ceiling joists

1.Mark and drill four holes, approximately 1¼" (32 mm) deep into the ceiling joists, using a 5/16" (8 mm) diameter drill bit.

2.Screw in the eye screws until they are secure.

NThe eye screws should not be screwed in directly above where the turnbuckles attach but offset about 10 degrees out from vertical (see figure 2).

Truss ceilings

Follow the steps in “Attaching the tie wire” section on page 8.

NThe point in the ceiling at which the wire is to be attached should not be directly above where the turnbuckles attach, but offset about 10 degrees out from vertical.
