Styles AQD-M Bracket / Installation Instructions
4.
Assemble the joint by
inserting the grooved end of
the sprinkler piping into the
opening of the coupling. The
grooved sprinkler piping shall
be inserted into the coupling
until contact with the center
leg of the gasket occurs. A
visual check is required to
verify that the coupling keys
align with the groove in the
sprinkler piping and engage
with the spacer on the inlet
end of the flexible hose.
WARNING
• The nut shall be tightened until metal-to-metal contact occurs at
the bolt pads, as indicated in steps 5 and 6.
• DO NOT overtighten coupling hardware.
Failure to follow instructions for tightening hardware could result in:
• Personal injury or death
• Bolt damage or fracture
• Damaged or broken bolt pads or coupling fractures
• Joint leakage and property damage
• A negative impact on system integrity

5.
Using an impact tool or a standard socket wrench with an
11/16
-inch (for Imperial nut)/17-mm (for Metric nut) deep well
socket, tighten the nut until metal-to-metal contact occurs at the
bolt pads. Verify that the oval neck of the bolt seats properly in the
bolt hole. DO NOT continue to tighten the nut after metal-to-metal
bolt pad contact is achieved.
If you suspect that any hardware
has been over-tightened (as indicated by a bend in the bolt,
bulging of the nut at the bolt pad interface, or damage to the
bolt pad, etc.), the entire coupling assembly shall be replaced
immediately.
NOTE:
During tightening, support the hose near the
Style 108 Coupling to verify that the inlet end of the Series AH2-CC
Flexible Hose remains straight and aligned with the coupling.
WARNING
• Visual inspection of each joint is required.
• Improperly assembled joints shall be corrected before the
system is tested or placed into service.
• Any components that exhibit physical damage due to improper
assembly shall be replaced before the system is tested or placed
into service.
Failure to follow these instructions could cause joint failure,
resulting in death or serious personal injury and property damage.

6. Visually inspect the bolt pads at each joint to verify that metal-
to-metal contact is achieved, in accordance with step 5.
