The shower channel is used in the bathroom as a drain for a floor-​level shower. The shower channel is designed for small to medium volumes of water, such as those occurring in the residential building sector, for example.

Technical information, see Technical data .

The shower channel is intended for draining of household-​type wastewater in constant operation, see Regulations from section: Media .

• The short-​term temperature of the wastewater may reach up to 95° C. The temperature must be considerably lower in constant operation.

• The pH value must be higher than four but lower than ten.

It is not permitted to introduce wastewater, which could damage the product material.

When two or three drains are combined using a collector line and a drainage capacity of > 0.8 l/s is expected, the dimensioning of the drainpipe must be DN 70.

The shower channel length is variably adjustable:

• The base unit can be shortened to a length of 300 mm with millimetre precision.

• The length of the shower channel can be extended up to 2800 mm by installing accessory parts.

The shower channel can be altered in the following way using the following accessories:

The following accessories are available:

end closing piece

Instead of the closing cap, a long so-​called "end closing piece" can be mounted onto the base unit. The base unit can therefore be extended accordingly.

Connection piece

The connector serves the purpose of connecting two base units with each other. In this case, one of the two base unit units must be shortened by the length of the connector (= 210 mm).

Connection piece 90°

The connection piece 90° enables the mounting shower channels in L- or U-​models.

The measured sound level during water drainage is 19 dB(A). For information on sound protection requirements met, see Regulations from section: Sound protection .

To protect against moisture penetration, apply sealing foils, which are to be processed in liquid state, directly below the tiles on screed and walls. The determination of the stress class and the underground as well as the selection of the suitable bonded sealing must be carried out in compliance with the valid standards and regulations, see: Regulations from section: Sealing .

Careful planning is required for professional sealing. In addition, depending on the individual dampness wear class and the type of foundation, a suitable thin bed bonded sealing with a building regulations certificate of suitability must be chosen.

Furthermore, the following factors should be taken into account:

• The drain or shower channel must be equipped with a special flange, which has an adhesive surface and a width of at least 50 mm.

• For bridging the material change from drain to screed, either a suitable sealing collar or sealing tape designed for overlapping with the thin bed bonded sealing over a width of at least 50 mm must be used.

• The screed must be laid at a minimum incline of 1–2%.

• The installation must be carried out properly in acc. with the mounting instructions and the manufacturer's information.

In connection with suitable drains, only approved bonded sealings with proof of practicability in keeping with building law may be used. See Regulations from section: Sealing .

Information regarding the procedure can be found in the instructions for use of the corresponding product.

Advantix shower channels and drains can both be fitted to be fire proof. The R120 pipe lead-​in can be used for this purpose in the floor construction. In this way, a fire resistance time of up to 120 minutes can be achieved.

For mounting instructions for the R120 pipe lead-​in see model 4923.5, art. no. 491 673.

Before assembly:

• Check if the drainage capacity of the model chosen is sufficient for the arising water volume  Drainage capacity .

• In the case of the connection of two or three shower channels: Observe the information for dimensioning of collective lines  Drainage capacity .

• An adequate level of floor covering stability must be guaranteed Technical data . This can be achieved either through an adequate screed thickness or another alternative solution. Relevant measures must be considered before mounting.

• The dimensions of slots and recesses must be in compliance with the regulations from section Regulations from section: Important notes .

During assembly:

• Observe installation dimensions.

• For barrier-​free showers:

  Position the shower channel in such a way that wheelchair wheels can only cross it at right angles. Viega recommends mounting the shower channel as close to the wall as possible.

• Do not use mounting adhesive older than 18 months.

• Position the shower channel in such a way that the grate is removable.

After assembly:

• The shower channel must be fully lined with mortar.

• The sealing accessories should be given to the person responsible for the bonded sealing (e.g. tiler).

• Coordinate all relevant installation details, especially regarding the bonded sealing, with those responsible for the subsequent work.

• Fork spanner size 13

• Hand saw (saw blade maximum 1.5 mm)

• One Allen key each of sizes 2.5 and 3

• Drill, 6 mm

• Tool for the removal of the grate (e.g. model 4965.90, art. no. 689 704)

Mounting adhesive can be used for a maximum of 18 months.

The filling date is found on the top edge of the cartridge. The first two numbers represent the month, the following number the year.

Example

Filling date = August (08) 2023 (3)

When a shower channel is installed in a niche, it is important for the niche to be large enough to remove the grate afterwards. The exact profile length must be calculated for this. The base unit without closing caps is taken as the profile length.

The basis for calculating the profile length is the shower niche after plastering (see dimension A).

The length of the closing caps is subtracted from this measurement. The result is the profile length.

You now have various possibilities:

• Mount the closing caps and base units. Mounting the closing caps on base unit

• Mount the extending parts. Pre-mounting extending parts

You must now calculate the height and align the shower channel Determine height .

Pre-​assemble all extending parts. Next, connect the pre-​assembled units to the base unit.

The following applies for mounting the feet:

• The maximum permissible distance between two feet is 400 mm.

• The maximum permissible distance between a foot and a fixing point of two parts is 100 mm.

  A fixing point is the point where two components are screwed together.

• During the mounting of connection pieces 90°:

  An additional foot must be mounted below the corner angle.

Requirements:

• The flange must be coated with protective foil.

If no cover trim is to be fitted, the floor can be tiled.

Further see Mounting without cover trim rail .

The floor can now be tiled.

Further see Mounting without cover trim rail .

Optionally, you can now insert the sieve, see Inserting the sieve .

Finally, a standing grate must be mounted, see Mounting the standing grate . See the catalogue for suitable standing grates.

Optionally, a sieve can be inserted. When the sieve is used, the drainage capacity decreases by 0.05 l/s per drain.

Finally, install a standing grate.

The total length of the shower channel increases if the basic model of the Vario shower channel is extended with other parts. In this case, the relevant accessory must be mounted for every extra part.

The upper edge of the standing grate holder must be approx. 1 mm below the upper edge of the tiles.

The cover caps can be moved by up to 9 mm (see fig,).

Normal soap or a mild cleaning agent can be used for regular maintenance and prevention of lime scale on the grate and frame. Use no scouring agent or abrasive objects.

Strong stains, even around the drain unit and the odour trap, can be removed using typical household cleaner. Rinse the detergent very thoroughly with clear water after the prescribed dwell time. There should be no residue on the components.

Viega recommends using a mild cleaning agent, a cloth and a washing-​up brush for cleaning.
