Complies with CE 0497 Directives.
Complies with EN 60947-1 and 60947-5-1 standards.
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, 1-4 closes.
In the pressure switch with blocking and manual reset at maximum pressure, the reset takes place when the pressure is below
