2.3.2 Drinking water connection
To prevent the intrusion of non-drinking water into the drinking water
pipelines, concealed pipe interrupters are installed between the mixer
tap and an inlet. The Viega concealed pipe interrupters can be used as
a safety mechanism, if the following points are ensured during installation:
n
The direction of flow runs from diagonally downward to vertically
downwards. Pipelines are not allowed to rise downstream from the
pipe interrupter.
n The pipe interrupter must be installed at least 150 mm above the
highest possible non-drinking water level.
n There must not be any shut-off downstream from the pipe inter-
rupter.
n The pipe interrupter must not be involved in the pressure test with an
installed membrane, the membrane is destroyed during a pressure
test and the pipe interrupter cannot perform its function. If a pressure
test is required, the insert with the membrane must be exchanged for
a connecting piece, model 6161.83.
n Pipe interrupters may only be used with compatible components.

Fig. 5: Minimum installation height 150 mm
Make sure that the pipe interrupter is installed at least 150 mm
above the highest possible non-drinking water level.
Note that the direction of flow must run from diagonal to vertical
downwards.
Make sure that the line does not continue to rise downstream from
the pipe interrupter.
Make sure that you have the required accessories (rosette, connection sets) to be able to carry out the mounting work completely.
Make sure that during assembly, the protective plug is to be found
on the top stem.
Depending on the type of mounting, the connection of the mixing tap
and the pipe interrupter can made with pipes and a press connection or
with plastic pipes.
Connecting the water inlet
Handling

To connect the water inlet:
Seal the adapter elbow and twist into the connection of the mixer
tap.
Connect the pipe of the pipe interrupter with the adapter elbow.
Push the union nut and clamping ring onto the water-bearing pipe.
Push the narrow end of the screw fitting into the pipe as far as it will
go.
Push the free end of the screw fitting into the connection of the pipe
interrupter.
Screw the connection together. Euro cone connections are not
compatible.

Screw the pipe interrupter tight with two screws (spanner size 4.5
up to 5).
Encase the pipe interrupter and connection line in mortar.
Tile the wall.
If the shaft top is too long:
Shorten shaft top with a fine-toothed saw. Take care to shorten to
the proper length. The shaft top must be flush with the height of the
tiles.
If impurities have managed to enter the shaft top during the work,
clean shaft top.

If the shaft top does not need to be shortened and it has been determined that there are no longer any impurities in the shaft top:
Remove protective plug.
Hold the rosette with the open side facing downwards.
Mount the rosette onto the shaft top.
3.2.2 Connecting the tub inlet
To connect the tub water inlet:
Push the union nut and clamping ring onto the water-bearing pipe.
Push the narrow end of the screw fitting into the pipe as far as it will
go.
Push the free end of the screw fitting into the connection elbow.
Screw in the pipe tight with the union nut onto the connection
elbow. Euro cone connections are not compatible.
Insert the connection elbow into the overflow unit. The connection
elbow must click into place in the overflow unit with a noticeable
clicking sound.

3.3 Cleaning and maintenance
NOTICE!
Product damage due incorrect maintenance
Limescale deposits can destroy or be detrimental to the
functioning of the membrane in the insert of the pipe interrupter and must therefore be removed. If the insert and the
membrane in the pipe interrupter are either not or incorrectly cleaned, then the product's functionality may be
restricted or destroyed. Non-drinking water can contaminate drinking water.
To ensure the constant functionality of the pipe interrupter:
– Have limescale deposits removed by trade professio-
nals, as described in this chapter.
– In the case of extensive limescale deposits have insert
and membrane replaced by trade professionals, as
described in this chapter.
Remove rosette.
Grip and pull the insert out of the casing using multigrip pliers horizontally.
