Corresponding to the requirements provided in the R.3.B. chapter of the applied technical specifications of D.M. dated December 1st 1975. BO1BM with I.S.P.E.S.L. homologation. INSTALLATION Direct installation on the pipe. 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. OPERATION When it is reached the blocking value of the pressure: 1-2 opens. To reset wait until the pressure drops below differential’s value and operate the reset button.
