Safety

A hydraulic safety unit protects the hot water heater or accumulator against the risk of explosion due to overpressure. The integrated safety valve automatically releases the water until the pressure falls below the nominal value. The non-return valve prevents contamination of the cold water supply by the return of hot water. The emptying of the installation is done by manually activating the valve in the direction of the arrows.

The installation of a safety group is mandatory in any hot water heater by accumulation. The siphon assembly is recommended.
