Schlüter-KERDI-LINE-VARIO is a flexible, multi-piece, linear drainage system for creating floor level showers with ceramic tiles or natural stone.

The two-piece horizontal KERDI-LINE-VARIO drain unit comprises a drain body and a drain adapter. The drain body consists of an ultra slim, wave-shaped drain that is rotatable by 360° and a built-in odour trap. The wave-shaped design achieves a high flow rate within the floor drain, which results in a self-cleaning effect.

The sound insulation membrane included in the set reliably prevents specific sound transmission of the drain body to the surrounding wall or floor structures and serves as a positioning aid for direct installation in a wall.

To guarantee an especially low assembly height, the drain adapter of KERDI-LINE-VARIO-H40 with integrated Schlüter-KERDI-FLEX collar comes fully inserted into the sealed wave-shaped drain and is secured with a clamping ring. The wave-shaped drain can be rotated by 360° when the clamping ring is released, which makes the drainage system adaptable to any connection configuration in the existing building.

The drain adapter of KERDI-LINE-VARIO-H50 can be individually cut to size to match the structural requirements on site.

The KERDI-LINE-VARIO-H set includes:

• Flat drain body with odour trap
• Drain adapter with integrated waterproofing collar and wave-shaped drain rotatable by 360
• Clamping ring
• Gasket
• Adapter DN 40/DN 50
• Protective lid for simple seal check
• Water inspection nozzle
• Corner seal
• Folding sound insulation element
• Spirit level to level the assembly
• Cleaning brushes, although the wave-shaped drain assembly prevents the accumulation of debris

Two design drainage profiles are available for KERDI-LINE-VARIO: KERDI-LINE-VARIO-COVE and KERDI-LINE-VARIO-WAVE. These can be individually cut to size, are height adjustable and are shipped with two matching end caps.

The pre-adhered elasticated KERDI collar integrated into the drain adapter ensures the reliable connection of the drain body to the bonded waterproofing assembly, both in the floor area and on upright walls. It is secured by a transparent protective lid during installation.

In conjunction with the waterproofing systems Schlüter-KERDI, Schlüter-DITRA, Schlüter-DITRA-HEAT or Schlüter-KERDI-BOARD and the matching system adhesives Schlüter-KERDI-COLL-L or Schlüter-KERDI-FIX, installers can create certified bonded waterproofing assemblies with connecting linear drainage. KERDI-LINE is a system component that complies with the German waterproofing standard DIN 18534. Together with the above-listed Schlüter-Systems it has general technical approval (abP) in Germany.

Please refer to the respective product data sheets for information about the moisture exposure classes according to abP. Schlüter-KERDI-LINE is a system component with European Technical Assessment (ETA) according to ETAG 022 (watertight covering kits). Schlüter products tested together with KERDI-LINE bear the CE mark.

Note:

Due to the variable drain construction, KERDI-LINE-VARIO requires the installation of a sloped screed. The surface of the screed must be waterproofed with DITRA (see product data sheet 6.1) or DITRA-HEAT (see product data sheet 6.4). Schlüter-SHOWERPROFILE-S and -R (see product data sheet 14.1) are supplementary components for creating a floor or wall connection. SHOWERPROFILE-S has a triangular design to conceal the sloped lateral edges of floor level showers. Waterproof the surrounding walls with KERDI (see product data sheet 8.1) or create a bonded waterproofing assembly with KERDI-BOARD (see product data sheet 12.1).

Soundproofing

For soundproofing as specified in DIN 4109, VDI 4100, ÖNORM B 8115-2 or SIA 181, the Schlüter-KERDI-LINE-SR sound insulation panel complies with impact sound, installation noise and user noise limits in certified assembly variants of KERDI-LINE-VARIO.

Installing the KERDI-LINE-VARIO-H 40

1. Position the KERDI-LINE-VARIO H40 drain body and adapter in the centre of the weight-bearing structure or over the supplied 4 mm sound insulation component (over a suitable impact sound insulation layer if necessary; see section on soundproofing for further details). Note the materials label on the protective lid. For optimum alignment, insert the supplied spirit level into the groove provided in the protective lid.
2. For installation directly by the wall, position the drain body with the adapter and protective lid immediately in front of the rising wall, with the 4 mm sound insulation component included in the set. This ensures a defined distance of 11 mm from the wall (excluding wall covering) when the 11 mm WAVE profile is used. If using COVE profiles, this results in a distance of 15 mm from the wall in combination with the sound insulation component. To achieve a distance of only 11 mm from the wall, the sound insulation component should be omitted when using COVE profiles. Alternatively, the difference can be offset with suitable material, e.g. 5 mm Schlüter-KERDI-BOARD.
3. To connect to the drainage pipe, use the supplied Allen key to open the clamping ring and align the drain body to suit the site conditions.
4. Next, check that the adapter is still inserted up to the limit stop. After this, re-tighten the clamping ring.
5. After connecting the assembly to the drain pipe, check once again that the positioning is as desired. To compensate for uneven areas or for height adjustment, you can also arrange the drain body with precision on a levelling layer.
6. Perform a leak test.
7. Install the sloped screed (2%) of the shower floor such that it completely surrounds the drain body and provides load transfer. Use the screwed-down protective lid as an alignment and levelling aid. It must be flush with the top surface of the screed.

Installing the KERDI-LINE-VARIO-H 50

1. Position the KERDI-LINE-VARIO H50 drain body on the weight-bearing structure or over the supplied 4 mm sound insulation component (over a suitable impact sound insulation layer if necessary; see section on soundproofing for further details). Note the materials label on the protective lid. To optimise alignment, insert the spirit level supplied into the groove provided in the drain body. Cut the drain adapter to match the height of the floor structure and carefully de-burr the edges, then loosen the clamping ring and insert the adapter into the drain body, using the lubricant supplied.
   Note: To ensure that the height of coverings with insulation can fluctuate, cut the drain adapter in such a way that it does not sit directly on the drain body.
2. For installation directly by the wall, position the drain body with the adapter and protective lid immediately in front of the rising wall, with the 4 mm sound insulation component included in the set. This ensures a defined distance of 11 mm from the wall (excluding the wall covering) when using Schlüter-WAVE profiles. If using Schlüter-COVE profiles, a distance results of 15 mm from the wall in combination with the sound insulation. To achieve a distance of only 11 mm from the wall, the sound insulation component should be omitted when using Schlüter-COVE profiles. Alternatively, the difference can be offset with suitable material, e.g. 5 mm Schlüter-KERDI-BOARD.
3. To connect to the drainage pipe, align the drain body as required by site conditions.
4. Check the fit between the adapter and drain body and then re-tighten the clamping ring.
5. After connecting the assembly to the drain pipe, check once again that the positioning is as desired. To compensate for uneven areas or for height adjustment, you can also arrange the drain body with precision on a levelling layer. The fixing set provided allows you the option of bolting the drain body directly to the weight-bearing structure.
6. Perform a leak test.
7. Remove the spirit level from the drain body prior to installing the screed. Then install the sloped screed (2%) of the shower floor area to create a weight bearing assembly that completely encompasses the drain body. Use the screwed-down protective lid as an alignment and levelling aid. It must be flush with the top surface of the screed.

Uncoupling and waterproofing

8. Remove the protective lid once the screed surface is ready to bear weight. Use thin-bed mortar to correct any flaws or gaps in the screed.
9. Now use thin-bed mortar to firmly bond the DITRA (recommended trowel notch size: 3 x 3 mm or 4 x 4 mm) or DITRA-HEAT (recommended trowel notch size 6 x 6 mm) to the screed surface. Cut the edge insulation strips and the sound insulation component to the required height. The format of tiles laid on DITRA or DITRA-HEAT must be at least 5 x 5 cm. (see also product data sheet 6.1 or 6.4).
10. To attach the KERDI collar, apply KERDI-COLL-L sealing adhesive (see product data sheet 8.4) to the adjoining waterproofing using a 3 x 3 or 4 x 4 mm notched trowel and fully embed the KERDI collar in the adhesive. The curing time of the adhesive must be observed.
11. Create and tightly seal the wall connections using KERDI-KEBA sealing tapes and KERDI-COLL-L.
12. Tiles or natural stone can be used as covering materials. (The covering thickness must match the selected drainage profile.)

Installation of drainage profiles

1. Cut the drainage profile to size with a suitable handsaw to suit site conditions, using the supplied cutting gauge (do not use an angle grinder) and deburr the cut.
2. The set includes two end caps to create a simple and elegant finish.
3. The aluminium COVE 26 and WAVE 34 profiles come with a cover frame, which is fitted snugly over the drain adapter beforehand using thin-bed mortar.
4. Adjust the height of the drainage profile by filling with thin-bed mortar until it is flush with or slightly below the covering surface. For optimum load transfer, be sure to avoid any cavities when embedding the drainage profile with mortar, particularly near to the drain opening.

Note:

KERDI-LINE-VARIO can also be used in timber structures. Please contact us for further details. KERDI-LINE-VARIO drainage profiles are intended for positioning in the wall and mid-floor areas of the shower and should not be placed near the entry to the shower.

Please contact our Technical Department with any questions.

The wave-shaped drain and drain adapter are made of high impact resistant polypropylene (PP).

The KERDI waterproofing collar that is pre-adhered at the drain adapter for connecting to the bonded waterproofing assembly (see product data sheet 8.1) is made of a polyethylene membrane.

The clamping ring at the wave-shaped drain is made from coloured polyvinyl chloride (PVC).

The protective lid is made of transparent acrylonitrile butadiene styrene (ABS).

Material properties and areas of application

Schlüter-KERDI-LINE-VARIO drainage systems are classified as K3 according to DIN EN 1253, Gullies for buildings. This class refers to areas without vehicle traffic. Apart from the aluminium version of the WAVE profile, all drainage profiles are able to withstand wheelchair use.

KERDI-LINE-VARIO drainage profiles are available in a wide variety of materials and finishes. Product suitability must be verified in applications exposed to chemical or mechanical stresses. The information provided below is intended as a general guideline.

The drainage profiles COVE and WAVE in the brushed stainless steel V4A version (material no. 1.4404 = AISI 316L) are particularly well suited for applications that, in addition to heavy mechanical stresses, require resistance to chemicals such as acidic or alkaline media and detergents. Their application areas include bathrooms in apartments, nursing homes, hotels and schools as well as public washroom and shower facilities. Even stainless steel is not resistant to all chemical stresses, and may be affected by e.g. hydrochloric and hydrofluoric acid or certain chloride and brine concentrations. In certain cases, this also applies to seawater pools. Special anticipated stresses should therefore be verified in advance.

The COVE and WAVE drainage profiles made of aluminium (textured coated aluminium) feature surfaces with a natural appearance. The aluminium is pre-treated (anodised) and powder-coated with a polyurethane covering. The colour-stable coating is UV and weather-resistant. Their application areas include bathrooms in apartments, nursing homes or hotels. Visible edges should be protected against abrasion.
