to secure the mounting bracket to a wall.
Table 3-3: Procedure to Secure the Mounting Bracket to a Wall
Step
Action
* IMPORTANT
Use the shoulder washers attached to the mounting bracket in each mounting hole to electrically
isolate the mounting bracket from the wall.
1
Insert a Hilti anchor into each mounting hole. Tap each anchor using a rubber mallet until each
anchor is completely seated in a hole.
2
Position the mounting bracket on the wall over the mounting holes. Start, but do not tighten all
bolts.
! CAUTION
Only put shims under the bracket where the isolation pad is present. Do not place shims so that
they will contact the bare metal of the frame.
3
Place a 4-ft (1.22 m) level on the bracket from top-to-bottom. Then, using metal shim material,
level the bracket.
4
Use a 15/16-in. (23.8 mm) socket, a ratchet wrench, and an 18-in. (45.7 cm) breaker bar, to
tighten the red cap of each anchor bolt until the red cap shears off.
NOTE
When the red cap shears off, the anchor bolt has been tightened to the correct torque.
