Handling
Assembly information
Mounting conditions
The following requirements exist for the mounting of the drain / overflow:
The bathtub is installed.
The drain pipeline is installed all the way to the bathtub.
The underside of the bathtub is accessible.
Pipe interrupter
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 installation, 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:
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.
Installation dimensions
The following values are valid for L (length) and H (height):
L = 100–260
H = 180–350
Required tools and materials
Tool
fine-toothed saw
mounting aid (included in the scope of delivery)
Allen key (size 3)
Material
No additional material is required for the complete mounting of the product.
Assembly
Connect and mount pipe interrupter
For subsequent installation of the bathtub, the pipe interrupter must be mounted before the work on the walls is completed, as shown in the diagram in Mounting conditions . Proceed as follows:
-
Note that the flow direction 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 completely.
-
Make sure that the protective plug is still on the top stem during assembly.
Mounting with the Viega plug connection is described in the following.
Mounting can also be carried out with other connecting materials. If necessary, observe the manufacturer's instructions.
-
Push the union nut and the clamping ring onto the water carrying 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.
INFO!Euro cone connections are not compatible.
Mounting with the Viega plug connection is described in the following.
Mounting can also be carried out with other connecting materials. If necessary, observe the manufacturer's instructions.
-
Seal the adapter elbow and twist it into the connection of the mixer tap.
-
Push the union nut and clamping ring onto the pipe.
-
Push the pipe onto the support body of the adapter elbow as far as it will go and screw it together with the union nut.
-
Lay the free pipe end to the connection point of the bathtub drain and overflow fitting.
-
Adjust the pipe interrupter.
NOTICE!Pay attention to the correct flow direction (direction of arrow, from top to bottom).
-
Mark the drill holes.
-
Drill the holes.
-
Screw the pipe interrupter tight with two screws (SW 4.5 up to 5).
-
Grout the pipe interrupter and the connection lines.
-
Integrate the pipe interrupter with mounted sealing collar into the bonded sealing.
-
Then tile the wall.
If the shaft top is too long:
-
Remove the protective plugs.
-
Shorten the 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, the clean the shaft top.
If the shaft top has not been shortened and it is ensured that no more contamination can enter the shaft top:
-
Remove the protective plug.
-
Hold the rosette with the open side facing downwards.
-
Mount the rosette on the shaft top.
Mounting overflow
Proceed as follows to the mounting of 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.

Place the O-ring in the annular gap of the fixing flange.
-
Hold the overflow unit on the overflow opening of the bathtub from the outside.
-
Screw the fixing flange into the overflow unit by hand.
NOTICE!Pliers or other tools may damage the fixing flange. Only turn the fixing flange by hand.
Mounting the drain
Proceed as follows to mount the drain:
-
Place the profile seal in the recess of the drain unit.
-
Mount the drain unit with profile seal on the drain hole of the bathtub from below.
-
Select a 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 mmhigh valve top for plastic tubs with wall thickness A = 11–16 mm.
-
Apply lubricant to the inside of the seal and place onto the underside 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.
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:
The overflow is mounted in the overflow opening.
The 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.

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
-

Simple maintenance and cleaning pipe
Care
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
Use normal soap or a mild cleaning agent for regular care and prevention of lime scale on the rotatable rosette and valve cone. Do not use scouring agent or abrasive objects!
Use household cleaner to remove coarse soiling, also around the drain unit and the odour trap. Rinse the detergent thoroughly with clear water after the prescribed exposure time. There should be no residue on the components.
Cleaning pipe interrupter
The pipe interrupter must be cleaned regularly, as limescale deposits on the membrane can impair its function. The cleaning interval depends on the local water quality and should be determined during assembly.
INFO!
In the event of heavy deposits, the insert and the membrane must be replaced in order to ensure that the pipe interrupter functions properly.
Proceed as follows to clean or replace the insert and membrane:
-
Remove rosette.
-
Pull the insert out of the casing using water pump pliers.
-
If only minor limescale deposits and contamination are visible, rinse the insert carefully.
-
If heavy limescale deposits and contamination are visible, use a new insert (model 6161.82).
-
Fit the insert vertically into the casing of the pipe interrupter from the front using water pump pliers.
-
Insert the rosette into the shaft top.
Cleaning the drain
The drain should be cleaned at regular intervals. The cleaning interval depends on how often the bathtub installation is used.
Proceed as follows to clean the drain:
-
Unscrew the cover plate by hand.
-
Loosen the Allen screws of the inlet element using the Allen key (SW 3).
-
Remove the inlet element.
-
Clean the inlet element under running water.
Do not use sharp or pointed objects for cleaning, as these could damage the material.
-
Loosen the square-head screw of the drain plug using a square-head key (SW 3).
-
Close the drain plug with the rotatable rosette and hold it in this position.
-
Remove the drain plug.
-
If the seal of the drain plug is damaged or heavily calcified, remove the seal.
-
Insert a new seal into the recess in the drain plug.
Only use original replacement seals from Viega (model 6162‑268) that are intended for the drain plug.
-
If necessary, clean the drain casing with running water and a mild detergent.
INFO!Do not use corrosive cleaners or pipe cleaners, as these can attack the plastic of the drain casing.
INFO!
Assembly is carried out in the reverse order.
Disposal
