3.1 Assembly information

3.1.1 Mounting conditions

The following requirements exist for the mounting of the drain / over­flow:

n The bathtub is installed.
n The drainage line is installed all the way to the bathtub.
n The underside of the bathtub is accessible.

Pipe interrupter

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.

Handling

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:

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.

3.4 Simple maintenance and cleaning pipe

3.4.1 Maintenance

NOTICE!
Risk of damage due to unsuitable cleaning agent.

The following cleaning agents can damage chrome-plated
surfaces and therefore may not be used:

– scouring agent
– abrasive sponges
– lime, plaster or cement dissolver
– solvents or other acidic cleaning agents

Normal soap or a mild cleaning agent can be used for regular care and
prevention of lime scale on the rotatable rosette and valve cone. Under
no circumstances should scouring agent or scratching objects be used.

Strong stains, even around the drain unit and the siphon, can be
removed using typical household cleaner. It should be noted that the
cleaning agent should be rinsed off after the prescribed soaking time.
There should be no residue on the components.

Multiplex Trio F drain/overflow functional unit 21 from 25

3.4.2 Cleaning pipe interrupter

The pipe interrupter must be cleaned regularly as limescale on the
membrane can be detrimental to its functionality. The cleaning interval
depends from the local water and should be decided during mounting.

Proceed as follows to clean or replace the insert with the membrane:

Handling

In the case of extensive contamination, the insert has to be
replaced to ensure the functionality of the pipe interrupter.

Remove rosette.

Pull the insert out of the casing using multigrip pliers.

If there is only a little limescale and contamination, rinse the insert
carefully.

Multiplex Trio F drain/overflow functional unit 22 from 25

Handling

If excessive limescale and contamination is found, use new insert
(model 6161.82)

Using multigrip pliers, insert the insert into the casing of the pipe
interrupter vertically from the front.

3.4.3 Cleaning the drain

Insert the rosette into the shaft top.

The drain should be cleaned at regular intervals. The cleaning interval
depends on the use of the tub installation.

Proceed as follows to clean the drain:

Multiplex Trio F drain/overflow functional unit 23 from 25

Unscrew cover plate by hand.

Loosen the Allen screws of the inlet element with the Allen key
(size 3).

Remove inlet element.

Handling

Clean inlet element by holding it under running water.
Do not use any sharp or pointed objects when cleaning as this could

damage the material.

Loosen the Allen screw of the valve cone with an Allen key (size 3).

Multiplex Trio F drain/overflow functional unit 24 from 25

Handling

Close the valve cone with the rotatable rosette and retain this posi­tion.

Remove valve cone.

If the seal of the valve cone is damaged or has excessive limescale,
remove the seal.

Place a new seal in the recess in the valve cone.
Only use original replacement seals from Viega (model 6162-268),

which are intended for the valve cone.

If necessary, clean drain casing with running water and a mild
cleaning agent.

INFO! Do not use any abrasive cleaner or pipe cleaner as
these can damage the plastic of the drain casing.

To install, follow the same steps in reverse order.

3.5 Disposal

Separate the product and packaging materials (e. g. paper, metal,
plastic or non-ferrous metals) and dispose of in accordance with valid
national legal requirements.
