HOMOLOGATION AND INSTALLATION
Homologation
- 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.
- Direct installation on the pipe.
- 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 the
value set on differential.
