Accessories
INFO!
The accessories shown here are not included in the scope of delivery. If required, it must be purchased separately.
Optional accessories
Equipment set with water level increase
The water level of the overflow can be increased by 5 cm with the equipment set. The equipment set contains a rotatable rosette, a fixing flange, a valve cone, a fixing screw, a flange cover and a mounting aid for the drain of the functional unit.
Equipment set Multiplex Visign M9: model 6171.0
Multiplex extension set
It is possible to extend the odour trap below the bathtub in the case of bathtubs with a very thick floor. The extension set, model 6161.7, is available for such cases.

Handling
Assembly information
Mounting conditions
The following requirements exist for the mounting of the drain / overflow:
The bathtub is installed.
The drainage line is installed all the way to the bathtub.
The underside of the bathtub is accessible.
Installation dimensions
The following values are valid for L (length) and H (height):

Required tools and materials
Tool
The following tools are required for mounting:
socket spanner (SW 14)
fine-toothed saw
flat-blade screwdriver
Material
No additional material is required for the complete mounting of the product.
Assembly
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.
-
Fit profile seal in the overflow unit.
-
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.
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 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 double seal onto the drain opening from below.
-
Pull the upper part 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 a socket spanner (SW 14).
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.
-
Hold the pipe of the overflow unit parallel to the overflow pipe and mark the positions where the drain and the overflow should be connected.
Maintain an insertion depth of at least 15 mm!
-
Cut the overflow pipe to the marked length and, if necessary, deburr.
-
Push the top end of the overflow pipe into the rubber sleeve.
Maintain an insertion depth of at least 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.
Connecting the wastewater system
Proceed as follows to connect the drain/overflow to the wastewater system:
Requirements:
The overflow and drain units are installed on the bathtub.
The connection between overflow and drain has been made.
The drainpipe has a diameter of 40 mm.
-
Push the union nut, sliding ring and sealing onto the drainpipe.
-
Screw the union nut on the drain unit.
Maintain an insertion depth of at least 15 mm!
Mounting equipment set
To avoid damage to the rosette and valve cone, only mount the equipment set after finishing all other work on the building site. Proceed as follows:
-
Align and fit rotatable rosette.
-
Fit valve cone.
-
Turn 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 union nut.
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 drain/overflow fitting for visible leaks.
Control
The drain / overflow are controlled via the rotatable rosette on the overflow. Proceed as follows to open or close the drain:
-
Turn rotatable rosette to the left.
-
The drain closes itself.
-
Turn rotatable rosette to the right.
-
The drain opens itself.
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.
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.
