Aquastop valve
3.5.1
Design
The Aquastop valve is an electromechanical safety valve. The coarse
and fine filters are located on the screw connection for the tap. Under
the filters is the flow limiter. It limits the water flow to 2.5 litres.
The Aquastop valve is enclosed by a housing. A leakage water hose
(external hose –> jacket around the supply hose) runs from the
housing into the base pan.
The leakage water hose contains the water supply hose and the
electric control cable for the solenoid valve.
3.5.2
Function
In the idle state the coil is de-energised and the seal interrupts the
water flow by the effect of the spring which presses on the armature.
If the Aquastop valve is connected to the water mains, the water
pressure also acts from behind on the seal and supports the sealing.
If leaks occur in the area of the valve or supply hose, these are
conveyed into the base pan via the leakage water hose.
A polystyrene float activates the electronic safety system via a micro-
switch. The coil of the AquaStop valve is deactivated by the elec-
tronics and interrupts the flow of water into the appliance.
