Pre-mounting:

  • Check that the nozzle drilling is appropriate for the zone to be protected.
  • Ensure that piping network supports are positioned so that the thrust cannot move the nozzle when the extinguishing agent is released.

To mount the nozzle on the piping:

  • Clean the threads on the nozzle and on the pipe end.
  • Apply an appropriate sealant to the nozzle thread.
  • Screw the nozzle on the piping by hand.
  • Tighten the nozzle using a 22 mm open-end wrench.
  • For nozzles fitted with a cap, check that this cap can easily be ejected in case of a discharge.
WARNING
Nozzle installation

Mount each nozzle at the location defined when the installation was designed.

Check that there are no obstacles in the path of the nozzle jets: ensure that there is sufficient room around the nozzle to guarantee effective discharge of the extinguishing agent.
