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:
– Liquids with a pH-value higher than 4
– typical household wastewater with temperatures up to
95 °C
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
particularly quietly through the overflow opening.
The drain/overflow is suitable for bathtubs with a middle connection.
Detailed information regarding all bathtub models and the corre-
sponding Viega drains / overflows can be found in the catalogue or on
the Internet.

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, there is a possibility that bath water may flow back
into the drinking water system.
To ensure that no bath water flows back into the drinking water system,
a pipe interrupter must be installed in the pipeline between the shut-off
fitting and the bathtub inlet.
The following schematic diagram shows what this should look like:
Pipe interrupter

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 top edge of the
bathtub.
Observe the local standards and regulations.

3.2 Assembly
3.2.1 Connect and mount pipe interrupter
The pipe interrupter must be mounted according to the plan in
ÄChapter 3.1.1 „Mounting conditions“ on page 9 for the subsequent
installation of the bathtub before the work on the walls is finished. Pro-
ceed as follows:
nThe direction of flow runs from diagonal to vertical downwards.
nThe line does not continue to rise downstream from the pipe inter-
rupter.
nAll of the accessories (pipes, connecting pieces ¾ inch) required for
complete assembly are included.
nDuring assembly, the protective plug is to be found on the top stem.
INFO! We show the mounting here with the Viega plug connec-
tion. Mounting can also be carried out with other connecting
materials. If necessary, observe the manufacturer's instructions.
Push the union nut and clamping ring onto the pipe.
Push Viega plug-in seat as far as it will go into the pipe.
Euro cone connections are not compatible.
Push the free end of the plug-in seat into the connection of the pipe
interrupter.
Using the union nut, screw the pipe tightly onto the pipe interrupter.
Repeat the procedure with the second pipe.
INFO! We show the mounting here with the Viega plug connec-
tion. Mounting can also be carried out with other connecting
materials. If necessary, observe the manufacturer's instructions.
Seal adapter elbow and twist into the connection of the mixer tap.

Select suitable valve top:
Use the B = 22.5 mm high flat valve top for steel tubs with wall
thickness A = 2–11 mm.
Use the B = 30 mm high valve top for plastic tubs with wall thick-
ness A = 11–16 mm.
Apply lubricant to the inside of the seal and place onto the under-
side of the valve top.
Install the valve top into the drain unit and screw together with the
mounting aid.
The mounting aid must be placed on the screw recesses with the
holes on the underside.
3.2.4 Connecting 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.
