Exchange of the Solenoid Valve / Replacement of the Flow Regulator

The Flow Regulator is already included in a replacement solenoid valve and, in this case,
NOTE
does not need to be replaced. Exception: If metering is set at 10 %, the flow regulator must
also be replaced in a new replacement solenoid valve.
The solenoid valve and / or flow regulator are to be replaced as follows:
 Pull out the mains plug and interrupt the water infeed (close the angle valve).
 Pull out plug (Item 1) and loosen nut (Item 2)
 Loosen swivel nuts (Item 3), remove solenoid valve (Item 4)
 Remove old flow regulator (Item 5) with a suitable tool
 Insert the new flow regulator (Item 6). You must make sure that the new flow regulator is
positioned correctly (see chapter 11.1, Fig. 11.1).
 Reinstall the solenoid valve in reverse order.
Ensure that the flat seal is correctly seated.
 Reconnect the electricity and water supply.
 Check that the device is functioning properly and make sure that it is not leaking.
13.3.3 Replacement of the Connecting Tube - Water Separation & Output
In the event of microbial contamination or to prevent this occurring, the flexible stainless
