INSTALLATION Direct installation on the pipe. MOUNTING MODEL If these devices are used as control pressostats (pressure lack), verify that maximum pres- N° 2 fori M4 sure does not exceed maximum supported sensitive element pressure. Possibility of mounting on metallic clamp, exept for the waterproof casing versions. 35 mm OPERATION When pressure increases: 1-2 opens, 1-4 closes. 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. In the pressure switch with blocking and manual reset at maximum pressure, the reset takes place when the pressure is below the value set on differential.
