6.
Install the gasket over the pipe end. Make sure the gasket lip does
not overhang the pipe end.
7.
Align the Victaulic FireLock CPVC No. 832 Grooved Adapter with
the IPS pipe end. Slide the gasket into position, and make sure it is cen-
tered between the grooves in the IPS pipe and the adapter. Make sure no
portion of the gasket extends into the grooves.
8.
Install the housings over the gasket. Make sure the housings’ keys
engage the grooves properly on the IPS pipe and the adapter.
9.
Install the bolts, and apply the nuts finger-tight.
NOTE:
Make sure
the bolt track heads seat properly in the bolt holes.
10.
Tighten all nuts evenly by alternating sides until metal-to-metal
contact occurs at the bolt pads. Make sure the housings’ keys completely
engage the grooves.
NOTE:
It is important to tighten all nuts evenly to
prevent gasket pinching.
11.
Inspect the joints before and after pressure testing. Look for gaps
between the bolt pads. Look for housing keys are that are not inside the
grooves. Ensure that pipe alignment does not place undue stress on the
grooved adapter. If any of these conditions are found, they must be cor-
rected immediately.
12.
The maximum recommended pipe hanger distance from the
grooved adapter is shown in the following table.
13.
As an added precaution, and to enhance the structural design of
the system, Victaulic suggests a hanger or support be located at or near
the grooved adapter joint. This hanger or support can be placed on
either side of the coupling. However, this is not a requirement, since the
hanger spacing values, shown in the table above, meet minimum UL
requirements.
WARNING
• Victaulic flexible couplings must have the nuts tightened until metal-to-metal contact
occurs at the bolt pads.
Failure to follow this instruction could cause joint failure, resulting in serious personal
injury and/or property damage.
