The wall drain is used as a drain for a floor-​level shower. The wall drain is dimensioned for small to medium volumes of water, which occur in, e.g. ,residential building. The wall drain complies with the requirements of the applicable regulations, see Standards and regulations .

Due to its flat installation height, the shower channel is especially suitable for the refurbishment of old buildings with a low floor thickness.

Technical information, see Technical data .

The shower channel is intended for draining common household wastewater in constant operation, see Standards and regulations .

• 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.

The shower channel length is variably adjustable:

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

• Installation variation 1 to 3: The standing grate with cap can be installed against a wall or glass partition without spacing.

• Installation variation 4 and 5: (wall offset to the rear): The standing grate with cap must be installed with spacing to the wall or glass partition.

If the drain line is to be installed in the lightweight construction wall, you can use the following drain:

Model 4966.18

The measured sound level during water drainage is 19 dB(A). For information on sound protection requirements met, see Standards and regulations .

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: Standards and regulations .

Careful planning is required for 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 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 Standards and regulations .

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 .

• 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 .

• As a rule, a wall construction of 25 mm is required. This can either be achieved through suitably thick cladding (also double planking of 2 x 12.5 mm) or through the application of a layer of plaster.

During assembly:

• Observe installation dimensions.

• The shower channel is suitable for the following covering thicknesses (tiles + tile adhesive):

  • Floor covering 8–28 mm

  • Wall covering 10–28 mm

• 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)

• Allen key size 4

• 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.

The variable installation possibilities of the Advantix Vario require careful planning of the assembly steps. Viega generally recommends the following order:

1. Calculate length and cut profile to length if necessary.
2. Pre-​mount all short profile parts.
3. Connect the pre-​mounted parts to the desired shape.
4. Calculate height and mount feet.
5. Mount base unit and align shower channel.
6. Line the shower channel with screed and seal.
7. Tile the floor.
8. Mount the standing grate.

Description of the assembly steps, see Assembly .

Depending on the installation situation, you will need to mount different end pieces to the profile.

• Installation situation in a corner: Mount the closing cap

• Installation situation at an uninterrupted wall: Mount the closing piece

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

With plastered wall

With XPS rigid foam board

With two gypsum plaster boards (12.5 mm each)

With XPS rigid foam board (20 mm)

Requirements

• Before mounting, the position of the CW profiles must be coordinated with the drywall builders.

• For corner mounting, the contact surfaces for the closing caps must be covered with cladding (12.5 mm).

Insufficient filling of the gap between floor covering and wall may result in formation of a hollow in the corner area of wall and floor tile (pos. 3). This hollow (gap) cannot be sufficiently sealed by means of a silicone joint. Dirty water which flows back may enter the gap and cause moisture damage.

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.

Standing grate holder

The standing grate holders consist of two parts.

Part one (A) is pushed into the end strip and can be moved on the strip. Part two (B) is pushed into part A. This part can be cut to length to produce the correct distance to the wall.

One pair of standing grate holders is mounted at each of the outer edges.

Standing grate supports

The standing grate supports support the standing grate over the length of the end strip.

The standing grate supports are available in three widths, matching the different thicknesses of the wall covering (tile adhesive + tiles).

Now, first determine the dimension of part B of the standing grate holder.

Measure the required dimension x from the outer edge of the wall covering up to the outer edge of the cover plate.

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.
