To adjust the pressure, follow the instructions below. The pressure
must not exceed 6 bar.
To adjust water pressure (if required):
1. Set the outlet pressure at least 1 bar below the inlet pressure.
2. Close the ball valve on the input side.
3. Reduce the pressure on the output side.
(e.g. by draining water)
4. Close the ball valve on the output side.
5. Loosen slotted screw. Do not unscrew the slotted screw
