Abstract (en)
[origin: EP1522353A1] The cleaner has a system separator (16) constructed according to DIN EN 1717. It is located in a regulator pipe (4,13), which branches off the fresh water feed pipe (17), and acts on the flow monitor (18) located on the high pressure side. When the cleaner is in use, the water volume flowing through the regulator pipe is approx. 1% to 10% of the water volume in the feed pipe, e.g. approx. 1 l/min in the regulator pipe, and approx. 33 l/min in the feed pipe. The system separator is located directly in or above the water tank (10), so that its outlet (25) is directed into the tank and this collects any water escaping due to faults. The system separator has test connections (23) for the three separate chambers. A chemical (20) is supplied from a container (21) via an outlet (22) into the water tank.
