INSTRUCTIONS FOR THE INITIAL
INSTALLATION OF A STYLE V9
DO NOT REMOVE
NUT/BOLT FOR INITIAL
INSTALLATION
1. DO NOT DISASSEMBLE THE STYLE V9: The Style V9 is designed
so that the installer does not need to remove the bolt and nut for
installation. This facilitates installation by allowing the installer to directly
install the Style V9 onto the sprinkler piping’s grooved end.
2. CHECK GROOVED END OF
SPRINKLER PIPING: The outside
surface of the sprinkler piping,
between the groove and the end
of the sprinkler piping, shall be
generally free from indentations,
projections, weld seam anomalies,
and roll marks to ensure a leaktight seal. All oil, grease, loose
paint, dirt, and cutting particles
shall be removed.
The sprinkler piping’s outside diameter (“OD”), groove dimensions,
and maximum allowable flare diameter shall be within the tolerances
published in current Victaulic IGS specifications, publication 25.14,
which can be downloaded at victaulic.com.
Gasket Grade
Color Code Mark
3. Check the gasket to verify
that it is suitable for the intended
service. The color code identifies
the material grade. Refer to
Victaulic publication 05.01 for
the color code chart, which can
be downloaded at victaulic.com.
Refer to the "NOTICE" on the
following page for important
gasket information.
3a. If any conditions listed in the "NOTICE" are met, apply a thin coat of
a compatible lubricant, such as Victaulic Lubricant or silicone lubricant,

I-V9 / Style V9 Victaulic® FireLock™ IGS™ Installation-Ready™ Sprinkler Coupling / Installation Instructions
WARNING
• Sprinklers cannot operate properly with bulb protectors in place.
• Bulb protectors shall be removed from all sprinklers before the
sprinkler system is placed in service.
• DO NOT use any tools to remove bulb protectors.
Failure to remove bulb protectors from all sprinklers before the
system is placed in service will cause improper sprinkler operation,
resulting in death or serious personal injury and property damage.
7. Remove the bulb protector
from all sprinklers carefully by

IMPACT WRENCH USAGE GUIDELINES
WARNING
• The bolt shall be tightened until metal-to-metal c ontact occurs
at the bolt pads.
• DO NOT continue to tighten the bolt after the visual installation
guidelines for the Style V9, described in steps 5 − 6 on page 2,
are achieved.
Failure to follow these instructions could cause joint failure,
resulting in death or serious personal injury and property damage.
Impact wrenches do not provide the installer with direct “wrench feel”
or torque to judge bolt tightness. Since some impact wrenches are
capable of high output, it is important to develop a familiarity with the
impact wrench to avoid damaging or fracturing the bolt or the coupling's
bolt pads during installation. Always choose the right size impact
wrench that has enough power, but DO NOT continue to tighten the
bolt after the visual installation guidelines for the Style V9, described
in steps 5 − 6 on page 2, are achieved. If you suspect that any
hardware has been over-tightened (as indicated by a bend or crack
in the bolt, etc.), the entire Style V9 assembly shall be replaced
imm edia tely.
If the battery is drained or if the impact wrench is under-powered, a
new battery pack or new impact wrench shall be used to ensure that
the visual installation guidelines for the Style V9, described in steps
5 − 6 on page 2, are achieved. Visual inspection of each joint is
required for verification of proper assembly.
Perform trial assemblies with the impact wrench and check the
assemblies with a torque wrench to help determine the suitability of the
impact wrench. Using the same method, periodically check assemblies
throughout the system installation.
For safe and proper use of impact wrenches, always refer to the impact
wrench manufacturer’s operating instructions. In addition, verify that
proper impact grade hex drivers are being used for Style V9 installation.
WARNING
Failure to follow instructions for tightening hardware could result in:
• Personal injury or death
• Bolt damage or fracture
• Damaged or broken bolt pads or fractures to housings
• Joint leakage and property damage
• A negative impact on system integrity
