filter inserts are inserted and lie in front of a small metal grill that is also inserted.

1 Switch off the leak detector.
2 Unscrew the capillary filter or the water conservation tip. Make sure that the
cone seal does not fall out.

Push the metal grill and then the two new inserts into the filter from the front.
Make sure that grill and inserts do not cant.
6 Switch on the leak detector.
7 Close the sniffer probe with your finger. With the water protection tip, you have
to also cover the opening on the side. You should then be able to feel a
negative pressure. If not then there is a leak somewhere and you have to check
the screw connection. The cone seal may also have fallen out.
