In the screw connection (3), the coarse filter (1) and the fine filter (2) are arranged
consecutively. The flow limiter (4) is situated under the filters. The electromagnetic
valve, consisting of the coil (5) and the seal (7), is located behind. After the seal,
the water duct of the Aquastop leads out into the inlet hose (10). The Aquastop is
enclosed within a housing (6).
The screw connection connects the Aquastop to the tap. The leakage water
hose (9) contains the control lead (8) and the inlet hose (10). The control lead (8)
connects the valve to the electronics.

Function
The Aquastop combines several functions:
The
coarse filter
and the
fine filter
filter particles out of the inflowing water and
prevent them from getting into the water circuit of the appliance.
The
flow limiter
reduces the flow cross-section of the water inlet depending on the
water pressure of the water connection.
The
valve
is an electromechanical safety valve. The valve coil is actuated by the
electronics. When voltage is applied to the coil, the water inlet seal is opened.
When the electronics switch off the voltage on the coil, the seal closes the water
inlet.
The
leakage water hose
feeds water into the base support which escapes in the
event of a malfunction in the area of the Aquastop or the inlet hose.
