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, 1-4 closes. If these devices are used as control pressostats (pressure lack), verify that maximum pressure does not exceed maximum supported sensitive element pressure. FEATURES Elements in contact with the fluid are in stainless steel, laser welded. Base, cover and knob in V0 self-extinguishing, shockproof thermoplastic material. Output connections with PVC cable gland. Maximum temperature of the controlled fluid: 120 °C. Pressure switch body admissible temperature: -35 ÷ 80°C. Storage and transport temperature: -35 ÷ 80°C.
