SPRINKLER REDUCING NIPPLE INSTALLATION
FOR STYLE AB1/AB7/AB10/AB11 BRACKETS
1. Move the center gate assembly of the Style AB1/AB7/AB10/AB11 Bracket to the
desired location. Loosen the wing nut to open the center gate assembly, then slide the
sprinkler reducing nipple into the center gate assembly.
NOTE: The pivot screw of the
center gate assembly is staked to resist removal of the wing nut.
For center-of tile installations, position
the center gate assembly between the
two reference marks on the square bar,
as shown to the left.
2.
Close the center gate assembly around the sprinkler reducing nipple. Swing the pivot
screw and washer into the slot on the gate, and tighten the wing nut to a torque of
50 inch-lbs/6 N•m (approximately hand-tight, plus 1/2 to 3/4 of a turn).
NOTE:
Verify that
the washer is seated under the head of the wing nut.
