Step 4:
Wrench tighten the Sprinkler using only the Socket
VC-H or Ratchet (3/8
″
drive) & Socket VC-H Combination (Ref.
Figure 4). The wrench recess of the Socket is to be applied to
the sprinkler wrenching area (Ref. Figure 4).
Step 5:
Use the “tolerance limit of ceiling level” indicator on the
Protective Cap to check for proper installation height (Ref. Figure 3).
Relocate the sprinkler fitting as necessary. If desired the Protective
Cap may also be used to locate the center of the clearance hole by
gently pushing the ceiling material against the center point of the Cap.
Step 6:
After the ceiling has been completed with the 2-inch (50mm) diameter clearance hole, use the Cap Removal Tool
(Ref. Figure 5) to remove the Protective Cap and then push on the Escutcheon until its flange just comes in contact with
the ceiling (Ref. Figures 6 & Figure 7).

Installation (Correct and Incorrect)
Do not continue to push on the Escutcheon such that it lifts a ceiling panel
out of its normal position. If the Escutcheon cannot be engaged with the
Sprinkler, or the Escutcheon cannot be engaged sufficiently to contact the
ceiling, relocate the sprinkler fitting as necessary.
