4.4 Aqua Stop valve
The Aqua Stop valve consists of two solenoid valves (A) in a row, the
filler and safety valves. These valves are actuated in parallel. There
are two filters on the screw connection for the tap. Under the filters
is the flow limiter.
4.4.1 Safety function
The safety function may be actuated via the safety level chamber
or via the float in the base pan.
The Aqua Stop valve is enclosed by a housing. The housing
is connected to the bottom pan by a leakage water hose (sleeve of the
inlet hose) (D). The inlet hose (C) and the electric control cable (B) for
the solenoid valve are situated in the leakage water hose (D). If leaks
occur in the area of the valve or inlet hose, these are conveyed into
the base pan via the leakage water hose.
