The raw water inlet module is attached directly behind the fresh water inlet upstream of water softening, pre-mounted ready for installation, and comprises:
Water filter to guarantee water quality
Water meter for targeted monitoring of consumption
Return flow prevention valve (required by many water works)
Two shut-off valves for easy maintenance
Connections are each ¾" female threads; the total length is 720 mm
How it works
To protect plant parts from contamination, and to prevent return flow of prepared water into the piping, it is recommended to use a filter and a pipe separator; in part, this is required by law (purs. to DIN1988).
