Schlüter®-Kerdi-Line

Installation

The following steps explain the Installation of the linear drainage systems. For detailed descriptions please refer to the Installation instructions for the following products:

  • Schlüter®-KERDI-LINE-H
  • Schlüter®-KERDI-LINE-H 50 G2
  • Schlüter®-KERDI-LINE-F
  • Schlüter®-KERDI-LINE-V
  • Schlüter®-KERDI-LINE-V 50 G2
  • Schlüter®-KERDI-LINE-D (covering support)

 
Installation with low construction height:
Schlüter®-KERDI-LINE-H, -H 50 G2 and -F are designed for horizontal drainage to a floor level. Schlüter®-KERDI-LINE-F is particularly well suited for renovation Projects due to its low assembly height of just 60 mm. If drainage through a floor level is a possibility, an installation height of ≥ 24 mm can be achieved with Schlüter®-KERDI-LINE-V.


Schlüter®-KERDI-LINE-H
Horizontal drain

  1. The channel support is installed on a level substrate with the appropriate height. To offset uneven sections or for height adjustment, the channel support may also be installed and aligned over several, sufficiently spaced spots of mortar or on a full layer of levelling screed. For wall installation, the channel body must be aligned in accordance with the thickness of the wall covering. For intermediate installation, use the supplied filling strip to create symmetrical dimension for the channel support.
    Note: To improve sound insulation in shower areas, install the insulating membrane Schlüter®-KERDI-LINE-SR and place a perimeter insulation strip along the edge area. Install the sound insulation membranes loosely on the level, solid ceiling with abutting seams. The printed side must be facing up. To avoid sound bridges, the seams can be covered with the seaming tape Schlüter®-DITRA-SOUND-KB. See the planning basis for further installation details of certified system assemblies – in accordance with noise insulation requirements of the corresponding standards and regulations.
  2. Fit the channel body into the channel support together with a custom cut drain pipe for connecting to the drainage system of the building. Perform a leak test.
  3. Next abut the sloped tray Schlüter®-KERDI-SHOWER-L, together with the levelling board if necessary , to the precisely installed Schlüter®-KERDI-LINE-H drainage channel at the correct height, flush with the upper edge of the channel support (see Product Data Sheet 8.8). As an alternative, you can also install a sloped screed at the correct height that is flush with the upper edge of the channel support. Schlüter®-BEKOTEC-DPS Dry Pack screed can be used for creating the sloped screed requirements.
  4. To integrate the Schlüter®-KERDI collar, apply the sealing adhesive Schlüter®-KERDI-COLL-L (see Product Data Sheet 8.4) to the adjoining waterproofing assembly with a 3 x 3 mm or 4 x 4 mm notched trowel and completely embed the Schlüter®-KERDI collar in this assembly. Observe the curing times of all materials. Use Schlüter®-KERDI-COLL-L to tightly seal the wall connections with Schlüter®-KERDI-KEBA.
    Installation with low construction height: Schlüter®-KERDI-LINE-H is designed for horizontal drainage on the floor level. If drainage is to go through at floor level, an installation height of ≥ 22 mm can be achieved with Schlüter®-KERDI-LINE-V.

 

Schlüter®-KERDI-LINE-H 50 G2
Horizontal drain with water trap height of 50 mm

  1. To achieve the minimum assembly height of 120 mm, shorten the adapter (maximum insertion depth 90 mm) up to a minimum insertion depth of 15 mm.
  2. Reattach the adapter to the channel body and screw it firmly into place.
  3. Place the drain casing on the adapter and firmly push it in.
  4. Apply thin-set adhesive to create a level substrate in the area of the channel support. Place the channel body with the channel support on the drain casing and firmly push it in. If necessary, apply spots of adhesive for height adjustment. Secure the drain casing against adapter slippage. For wall installation, the channel body must be aligned in accordance with the distance from the wall and thickness of the wall covering (see installation examples 4a and 4b).
  5. Connect and align the on-site drain pipe.
  6. Now apply the sloped screed (2%) of the shower area, over a suitable insulation layer if applicable.
  7. Apply thin-bed adhesive to the screed. A notched trowel size of 3 x 3 or 4 x 4 mm is recommended for installing DITRA 25. Use size 6 x 6 mm for installing DITRAHEAT.
  8. Now adhere Schlüter®-DITRA 25 or -DITRA-HEAT, sealing seams with Schlüter®-BAND and Schlüter®-KERDI-COLL- L (see product data sheet 6.1 and 6.4).


... For additional steps, see Schlüter®- KERDI-LINE-H (from item 4).


Schlüter®-KERDI-LINE-F
Horizontal drain forward facing

  1. Place the supplied gasket on the outlet of the channel body (note position).
  2. Now attach the drain body in place, by pushing onto the gasket.
  3. Apply thin-bed adhesive on the even and level substrate and set the channel support in place. To offset uneven sections or for height adjustment, the channel support may also be installed and aligned over several, sufficiently spaced spots of adhesive or on a full layer of leveling screed. For perimeter wall installation, the channel body must be aligned in accordance with the thickness of the wall covering. For intermediate installation, use the supplied filling strip to create symmetrical dimensions for the channel support.
  4. Now connect the drain body to the buildings drain system. Adjust the channel body with a spirit level and check for leaks.
  5. Install the sloped screed (2%) of the shower area against the precisely installed and levelled Schlüter®-KERDI-LINE-F. Schlüter®-BEKOTEC-DPS Dry Pack screed can be used for creating the sloped screed requirements.
  6. Once the screed is ready to bear weight, solidly embed Schlüter®-DITRA 25 on the screed area with thin-bed tile adhesive (recommended notched trowel size 3 x 3 mm or 4 x 4 mm). The tile format for installation over Schlüter®-DITRA 25 must be at least 5 x 5 cm (see also Product Data Sheet 6.1). 7. To adhere the Schlüter®-KERDI collar, apply the sealing adhesive Schlüter®-KERDI-COLL-L (see Product Data Sheet 8.4) to the adjoining waterproofing assembly with a 3 x 3 mm or 4 x 4 mm notched trowel and completely embed the Schlüter®-KERDI collar in this assembly, observing the curing times of all materials. Use Schlüter®-KERDI-COLL-L to create tightly sealed wall connections with the Schlüter®-KERDI-KEBA sealing band.
