Schlüter®-KERDI-DRAIN

Installation of Schlüter®-KERDI-DRAIN

Installation of Schlüter®-KERDI-DRAIN with drain casing

  1. The Schlüter®-KERDI-DRAIN drain casing (a) is integrated into the floor assembly and connected to the drainage system (Fig. 1).
  2. If required, sound or heat insulation may be installed (Fig. 2).
  3. The construction cover of the drain housing (Fig. 3) is removed and the thin-set insert Schlüter®-KERDI-DRAIN (b) is cut to the height of the floor assembly (Fig. 4). The unit is set on top of the floor drain (Fig. 6) and pushed into place (using a lubricant if required). Note on Fig.6: To allow for sufficient height movement of coverings with insulation, cut the neck to such a length that it does not sit on the bottom of the drain housing.
  4. The screed is then placed and aligned flush with the trapezoid-perforated bonding flange of the Schlüter®-KERDI-DRAIN thin-set insert (b).
  5. By adhering the Schlüter®-KERDI Collar (c), a waterproof connection to the screed surface is achieved (Fig. 7). The connecting waterproof layer, consisting of Schlüter®-KERDI or a trowel-applied system, is connected to the collar with a sufficient overlap. If Schlüter®-DITRA 25 is used as the waterproof layer, it is carried to the edge of the perforated bonding flange. Then, ensuring solid coverage, Schlüter®-KERDI Collar is set, overlapping the DITRA 25 membrane. Schlüter®- KERDI Collar is best adhered with the sealing adhesive Schlüter®- KERDI-COLL-L.
  6. Coatings or tiles can be applied as surface coverings. The height of the grate (e) is adjusted via the adjustment collar (d). The grate is set with adhesive and aligned flush with the covering (Fig. 8). Since the neck of the grate (e) has a smaller diameter than the thin-set insert (b), the grate can be positioned to match the joint pattern of the tile covering.
Note: Schlüter®-KERDI-DRAIN can also be installed in wood constructions. Further details are available upon request.

Notes
Schlüter®-KERDI-DRAIN requires no special maintenance or care. Stainless steel surfaces exposed to the environment or aggressive substances should be cleaned periodically using a mild household cleaner. Regular cleaning maintains the neat appearance of stainless steel and reduces the risk of corrosion. All cleaning agents must be free of hydrochloric and hydrofluoric acid. The stainless steel grate and the odour trap may be removed to clean the drain casing and the drain pipes.

Installation of Schlüter®- KERDI-DRAIN-BASE

  1. The drain casing Schlüter®-KERDIDRAIN-BASE (a) is placed on the support structure (using suitable impact insulation if required) and connected to the drainage pipe. If necessary, the supplied adapter piece DN 40/50 (b) is used for this purpose.
  2. The screed is installed in such a way that the trapezoid-perforated flange of the Schlüter®-KERDI-DRAIN thin-set insert (c) is flush with the upper edge of the screed (see Fig. 1).
  3. Attaching Schlüter®-KERDI Collar (d) with the sealing adhesive Schlüter®KERDI-COLL-L creates a waterproof transition to the screed area. The connecting waterproof layer, consisting of Schlüter®-KERDI or a trowel-applied system, is connected to the collar with a sufficient overlap. If Schlüter®-DITRA 25 is used as the waterproof layer, it is carried to the edge of the perforated bonding flange. The Schlüter®- KERDI Collar is now embedded with full overlap on the DITRA 25 mat. Schlüter®- KERDI Collar is best adhered with the sealing adhesive Schlüter®- KERDI-COLL-L. The corresponding installation instructions must be observed if Schlüter®-KERDIDRAIN-BASE is installed together with Schlüter®-KERDI-SHOWER (Fig. 2).
  4. Suitable covering materials include coatings or ceramic tiles (covering thicknesses 3-15 mm). Without using lubricants, the stainless steel grate (Fig. 3) is pushed in place. The grate is set with adhesive (Fig 4) and aligned flush with the covering.
  5. Prior to using the drain, remove the stainless steel grate and push down on the odour trap to check its positioning (Fig. 5; if necessary, apply some lubricant to the O-ring).
Note:
Schlüter®-KERDI-DRAIN can also be installed in wood constructions. Further details are available upon request.

Installation Schlüter®-KERDI-DRAIN thin-set floor drain

  1. After the installation of impact or heat insulation, if applicable, the thin-set floor drain (a) is positioned in accordance with the height of the floor assembly and connected to the drainage system.
  2. The screed is then installed in such a way that the trapezoid-perforated flange of the Schlüter®-KERDI-DRAIN insert (Fig. 1) is flush with the upper edge of the screed.
  3. By adhering the Schlüter®-KERDI Collar (b) with the sealing adhesive Schlüter®KERDI-COLL-L a waterproof connection to the screed surface is achieved (Fig. 2). The connecting waterproof layer, consisting of Schlüter®-KERDI or a trowel-applied system, is connected to the collar with a sufficient overlap. If Schlüter®-DITRA 25 is used as the waterproof layer, it is carried to the edge of the perforated bonding flange. The Schlüter®- KERDI Collar is now embedded with full overlap on the DITRA 25 mat. Schlüter®- KERDI Collar is best adhered with the sealing adhesive Schlüter®- KERDI-COLL-L.
  4. Coatings or tiles (Fig 3) can be applied as surface coverings.

Installing of the Schlüter®-KERDI-DRAIN covering support

  1. The installation of the covering can begin as soon as Schlüter®-KERDI Collar has been adhered with the sealing adhesive Schlüter®-KERDI-COLL-L. Suitable covering materials include ceramic tiles or natural stone.
  2. Covering support with substructure and adjustment collar. Thin-bed mortar is applied to the thin-set floor drain (Fig. 1a). The stainless steel frame with the perforated holes is placed into the recessed openings of the adjustment collar (Fig. 2a) and embedded it in the thin-bed mortar (Fig. 3a). Covering support with substructure and integrated odour trap. The stainless steel grate with neck is placed into the thin-set insert (Fig. 1b), set in mortar (Fig. 2b), and then pushed in to the maximum depth (Fig. 3b).
  3. Once the spacer has been placed, the installation of the covering can begin. It is important to install the covering directly adjoining the spacer at the frame (Fig. 4). Any excess mortar must be wiped off after removing the spacer.
  4. Place thin-bed adhesive on the covering support (Fig. 5) and adhere it to the matching covering cut-out of 8.2 x 8.2 cm (Fig. 6) to create a peripheral water drainage gap of at least 5 mm (Fig. 7).

Note:
For neat appearance, it is recommended to use a wet cutting machine for custom cuts and to bevel the edges. The installation instructions included with the drain casing also must be observed.
