any tools or bolt retaining devices and
ensure that the
membrane
is not
da-
maged
by sharp objects or tools (such
as by jewelry). The membrane may
be screwed onto the screw (approx.
5 turns) only until there is slight re-
sistance.
On no account should you
continue to turn it; otherwise, the
membrane can be damaged.
Now
carefully
stretch the silicone
membrane over the edge of the stain-
less steel cylinder. The membrane
should be flush with the outside of
the cylinder (Fig. 30).
While pushing the lower clamping ring
upward again and placing the upper
ring flush, pay attention that the mem-
brane does not
slip
or is accidentally
removed (Fig. 31).
The membrane is NOT glued to the
edge, but it can adhere to it strongly
when subjected to stable pressure.
To avoid damage, proceed particularly
carefully
when removing it and
do not
use pointed or sharp tools.
Do not use harsh cleansers. After
completely removing the membrane,
unscrew it from the bottom and take
it out.
The M10 stud screw at the
bottom of the stainless steel cylin-
der is attached using a bolt retaining
device and must not be removed.
4. Clean the Symphonie Aqua sys-
tem solely with water and mild soap.
Use only soft cloths. Ensure that no
soap residue remains in the cylinder.
5. After removing the packing mate-
rials, screw the new membrane onto
the stud screw located on the bottom
of the cylinder (Fig. 29). Do not use

The upper flange ring can now be remo-
ved (Fig. 27). The lower one is pushed
about 2 cm downwards (Fig. 28).
2. The water can now flow out. Since
low pressure is produced in the sys-
tem during discharge, the silicone
membrane moves to the interior wall
of the cylinder and prevents further
drainage. To achieve complete draina-
ge, air now needs to be supplied ca-
refully using the hose end so that the
membrane can detach from the inner
wall. The remaining water can drain by
tilting the cylinder.
Also drain the compensation reservoir
of the Symphonie Aqua system.
3. To replace the membrane, place the
Symphonie Aqua system on a raised
work surface. Now use the 4mm Allen
key and a 10 mm open-ended or ring
wrench to remove the nine screw con-
nections of the white rings (Fig. 25)
After the cover nuts have been remo-
ved, set them aside together with the
screws and the washers (Fig. 26).
