5.1 Check the direction of flow and change if
necessary
In the delivery state the direction of flow is from
left to right (heed flow direction arrow – visible on
the brass body below the handle). It is possible to
change this prior to filter installation – without con-
nection screw joints and manometer:

(90° clockwise)
- Open lever (1) by
approx. 80° - 90°
- Remove the black
cover on the reverse

- Loosen bolt
(anti-rotation device)
- Rotate the brass
housing by 180°
- Reinsert the bolt
(anti-rotation device)
The direction of flow is
now from right to left.
