• HOMOLOGATION AND INSTALLATION
  Homologation

  • Complies with CE 0497 Directives.
  • Complies with EN 60947-1 and EN 60947-5-1 standards.
  • Corresponding to the requirements provided in the R.3.B. chapter of the applied technical specifications of D.M. dated December 1st 1975 R.3.B.

  Installation and use

  • Direct installation on the pipe.
  • Pressure element connection G 1/4.
  • In case of fluid temperatures higher than the maximum allowed, connect the pressure switch to the pipe by inserting a metallic spiral between the pressure switch and the pipe to facilitate heat dispersion.
  • Possibility of mounting on metallic clamp, exept for the waterproof casing versions.

  • When pressure increases: 1-2 opens.
  • For use in connection with a regulation pressostat.
