Installation

► Installation is performed by following the above instructions in the reverse order. Observe the follow

ing points:

▪ Check that the white connection pieces are seated firmly on the segments. If these are loose, you

will need to replace the entire star.

▪ Make sure that there is an even space between the hoses:

▪ When fitting the star, make sure that the silicone hoses are not pinched and/or damaged.

CAUTION!

If the connecting silicone hoses between the valve and

segment are replaced, make sure that they are not dam

aged by rubbing against one another (2).

To ensure this, make sure that the silicone hoses have

been cut to the exact length and that they are pushed

onto the respective connection pieces as far as possible

(up to the stopper).

Make sure that the hoses do not touch (1) one another.

Check the distance while pushing all segments all the

way in. Ideally, the distances should all be the same.
