2.1 Intended use
2.1.1 Areas of use
NOTICE!
Risk of damage due to unsuitable liquids
To avoid damaging the drain, only introduce the following
liquids:
nTypical household wastewater with temperatures up to
95 °C
nThe pH value must be higher than 4 but lower than 10.
The Multiplex Trio drain/overflow is a combined inlet, drain and overflow
with odour trap for bathtubs with a 52 mm drain hole. The inlet flows
through the overflow opening.
The drain/overflow is suitable for standard bathtubs with the drain on
the head end.
Detailed information regarding all bathtub models and the corre‐
sponding Viega drains/overflows can be found in the catalogue or on
the Internet.

The accessories shown here are not included in the scope
of delivery. If required, it must be purchased separately.
Pipe interrupter
To ensure that no bath water flows back into the potable water installa‐
tion, a pipe interrupter must be installed, e.g. the connection set with
concealed pipe interrupter DN 20, model 6161.86. A suitable cover
rosette for the pipe interrupter must be purchased separately.

3.1 Assembly information
3.1.1 Mounting conditions
The following requirements exist for the mounting of the drain / over‐
flow:
nThe bathtub is installed.
nThe drainage line is installed all the way to the bathtub.
nThe underside of the bathtub is accessible.
Backflow situation: If a negative pressure situation should occur when
the bathtub is filled, bath water may flow back into the potable water
installation.
To ensure that no bath water flows back into the potable water installa‐
tion, a pipe interrupter must be installed in the pipeline between the
shut-off valve and the bathtub inlet.
The following schematic diagram shows what this should look like:

≥
Fig. 2: Mounting scheme with pipe interrupter
It is important that the pipe interrupter is mounted vertically, in the
direction of flow and at least 150 mm above the upper edge of the
bathtub.
Observe the local standards and regulations.

3.2 Assembly
3.2.1 Mounting the overflow
Proceed as follows to mount the overflow:
▶Push the rubber sleeve onto the pipe of the overflow unit.
The lower edge must be flush with the edge of the overflow pipe.
▶Fit the profile seal in the overflow unit.
▶If the wall thickness a is less than 3 mm (steel bathtubs only), insert
the addition seal between profile seal and bathtub.
▶Fit the supply flange into the overflow unit.

▶Screw in the fixing screw and tighten hand tight with the mounting
aid.
On the hexagon of the mounting aid, there is a groove, which must
be positioned on the lip of the fixing screw.

3.2.2 Mounting the drain
Proceed as follows to mount the drain:
▶Place the double seal onto the drain unit in such a way that the
recess is positioned above the connecting pipe.
▶Pull the edge of the double seal over the edge of the drain.
▶Hold the drain with the double seal onto the drain hole of the
bathtub from below.
▶Pull the top of the double seal through the drain hole.
▶Fit the valve top in the double seal.
INFO! The cross-shaped structures of the drain unit and
the valve top must be positioned parallel on top of each
other to ensure the full drainage capacity.
▶Place the fixing screw in the drain unit and tighten using the
mounting aid.

▶Insert the site protection.
3.2.3 Connecting the overflow and drain
After the overflow and the drain have been mounted, you must connect
them both using the overflow pipe. Proceed as follows:
Requirements:
nThe overflow is mounted in the overflow opening.
nThe drain is securely mounted on the base of the bathtub.
NOTICE! Connections where the pipes are not inserted far
enough into each other become leaky. For this reason, maintain
a minimum insertion depth of 15 mm for every connection.
▶Hold the pipe of the overflow unit parallel to the overflow pipe and
mark the positions where the drain and the overflow should be con‐
nected.
Minimum insertion depth: 15 mm
▶Cut the overflow pipe to the marked length and deburr it.
▶Push the top end of the overflow pipe into the rubber sleeve.
Minimum insertion depth: 15 mm
▶Push the union nut, sliding ring and seal onto the bottom end of the
drain elbow.
▶Screw the union nut on the drain unit.

3.2.4 Connecting the wastewater system
Proceed as follows to connect the drain/overflow to the wastewater
system:
Requirements:
nThe overflow and drain units are installed on the bathtub.
nThe connection between overflow and drain has been made.
▶If the wastewater pipe only has a diameter of 40 mm, cut off drain
elbow.
▶Push the union nut, sliding ring and seal onto the drain elbow.
▶Screw the union nut on the drain unit.
Minimum insertion depth: 15 mm
▶Align the odour trap in such a way that the drain elbow can be con‐
nected to the wastewater pipe.
Turn the drain at the two joints until the required position has been
reached.
▶Push the wastewater pipe in the drain elbow.

nThe overflow and the drain are mounted.
nThe overflow and the drain are connected.
nThe connection to the wastewater system has been made.
INFO! Mounting with the Viega plug connection is described in
the following. Mounting can also be carried out with other con‐
necting materials. If necessary, observe the manufacturer's
instructions.

set) onto the water-carrying pipe.
▶Push the narrow end of the screw fitting (part of the connection set)
into the pipe as far as it will go.
▶Push the free end of the screw fitting into the connecting piece.
▶Use the union nut to screw the pipe tight at the connecting piece.

3.2.6 Mounting the equipment set
To avoid damage to the rosette and valve cone, mount the equipment
set only after finishing all other work on the building site. Proceed as fol‐
lows:
▶Place the flange cover onto the supply flange with the straight side
facing downwards and affix.
▶Align and fit the rotatable rosette.
▶Fit the valve cone.
▶Turn the rotatable rosette to check function and alignment.
The opening of the valve cone should be 2–3 cm wide when
opened. If necessary, regulate the width of the opening of the valve
cone using the adjusting screw (see next step).
▶Set the valve cone with the help of the adjusting screw and counter
with the nut.
3.2.7 Leakage test
The leakage test is only carried out as a visual inspection.
Check the points marked in the following drawing with particular care:
▶Check for visible leaks.
3.2.8 Removing the rotatable rosette
If the rotatable rosette on the overflow is to be removed, proceed as fol‐
lows to prevent damaging the rosette and the flange cover:

3.3 Use
The drain / overflow are controlled via the rotatable rosette on the over‐
flow. Proceed as follows to open or close the drain:
▶Turn the rotatable rosette to the left.
▷The drain closes itself.
▶Turn the rotatable rosette to the right.
▷The drain opens itself.
There is a regulator for the water jet on the underside of the rotatable
rosette. Proceed as follows to adjust the water jet:
▶Push the flow control backwards or forwards with your finger. The
water flows closer or further away from the side of the bathtub
depending on the direction set.
