Using
Commissioning Port
3. Remove commissioning plug from valve.
For valves that have a commissioning port on the top face, a special plug (part # XTH104-73,
sold separately) can be used to seal off the cylinder when commissioning to save time and
removes the need to fill the cylinder.
1. Screw commissioning plug into valve port.
Make sure O-rings are clean and not damaged
before installing.
1/4” Hex head
Recommended
Torque: 30Nm
Internal leaking will come through the vent hole in the
center of the commissioning plug.
4. Insert blank plug into port and tighten to
fitting suppliers recommendations and leak test.
2. Leak test system before commissioning.
Make sure all valves are open.
Ensure pressure is vented from system when
complete.
