1-INCH/DN25 IGS CONNECTION TO THE
SPRINKLER PIPING USING A SERIES AH2-CC
FLEXIBLE HOSE
INCORRECT - Orignal Groove System (OGS) Groove Profile
CORRECT - IGS Groove Profile
Pipe and grooves are not shown to scale
The Style 108 Coupling of the Series AH2-CC shall be used
ONLY
with sprinkler piping connections that are prepared to Victaulic IGS
proprietary groove specifications.
DO NOT
attempt to install the
coupling on sprinkler piping connections that are prepared to any other
groove specification. Refer to Victaulic publication 25.14 for the IGS
groove specification, which can be downloaded at victaulic.com.
WARNING
• The flexible hose shall not be bent or fluctuated up-and-down or
side-to-side when pressurized.
Failure to follow this instruction could cause improper sprinkler
operation, resulting in death or serious personal injury and property
damage.
DO NOT REMOVE
NUT/BOLT/LINKAGE FOR
INITIAL INSTALLATION
1. DO NOT DISASSEMBLE THE COUPLING:
The Style 108 Coupling
of the Series AH2-CC is designed so that the installer does not
need to remove the nut, bolt, or linkage for initial installation. This
facilitates installation by allowing the installer to directly insert the
sprinkler piping’s grooved end into the coupling.
2.
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 leak-tight 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.
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, and the “NOTICE” below for
important gasket information.
CAUTION
• If any conditions listed in the "NOTICE" below are met, a thin
coat of a compatible lubricant shall be applied only to the gasket
sealing lips to help prevent pinching, rolling, or tearing during
installation.
• DO NOT use excessive lubricant on the gasket sealing lips.
Failure to use a compatible lubricant may cause gasket damage,
resulting in joint leakage and property damage.
3a.
If any conditions listed in the “NOTICE” below are met, apply a
thin coat of a compatible lubricant, such as Victaulic Lubricant
or an EPDM-compatible lubricant, only to the gasket sealing lips.
Silicone grease may be used (silicone spray is not a compatible
lubricant).
NOTICE
• Gaskets for Style 108 Coupling assemblies of AH2-CC Flexible
Hoses are pre-lubricated. Additional lubrication is not required
for the initial installation of wet pipe systems that are installed
at or continuously operating above 0°F/–18°C.
Supplemental lubrication is required only if any of the following
conditions exist. Apply a thin coat of a compatible lubricant to
the gasket sealing lips, as noted in step 3a on this page. It is
not necessary to remove the gasket from the housings to apply
additional lubricant to the gasket sealing lips.
• If the installation or continuous operating temperature is below
0°F/–18°C
• If the gasket has been exposed to fluids prior to installation
• If the surface of the gasket does not have a hazy appearance
• If the gasket is being installed into a dry pipe system
• If the system will be subjected to air tests prior to being filled
with water
• If the gasket was involved in a previous installation
Lubricated gaskets will not enhance sealing capabilities on
adverse sprinkler piping conditions. Sprinkler piping condition
and preparation shall conform to the requirements listed in these
product installation instructions.
WARNING
• Never leave a Style 108 Coupling of a Series AH2-CC partially
assembled on grooved sprinkler piping. ALWAYS TIGHTEN THE
HARDWARE IMMEDIATELY IN ACCORDANCE WITH THESE
INSTRUCTIONS. A partially assembled coupling poses a drop or
fall hazard during installation and a burst hazard during testing.
• Keep hands away from the grooved sprinkler piping and the
openings of the coupling when attempting to insert the grooved
sprinkler piping into the coupling.
• Keep hands away from coupling openings during tightening.
Failure to follow these instructions could result in death or serious
personal injury and property damage.
