Installation of Schlüter®-KERDI-DRAIN with drain body

1. Install the drain body Schlüter-KERDI-DRAIN  in the support structure and connect it to the drainage pipe. 2. If required, sound or heat insulation may be installed next.
2. Remove the protective cap, cut the bonding flange insert Schlüter-KERDI-DRAIN  to size in accordance with the height of the floor assembly and insert it firmly into the drain body (using lubricant if necessary). Note: To allow for sufficient height movement of coverings with insulation, shorten the bonding flange insert in such a way that it is not in full contact with the drain body.
3. Now install the screed in such a way that the trapezoid perforated flange of the Schlüter-KERDI-DRAIN bonding flange insert  is flush with the upper edge of the screed.
4. Attach a Schlüter-KERDI collar with the sealing adhesive Schlüter-KERDI-COLL to create a waterproof transition to the screed. In a next step, install the bonded waterproofing assembly of Schlüter-KERDI or a trowel applied sealing compound with a sufficient overlap over the collar. If Schlüter-DITRA 25 is used for waterproofing, bring the mat all the way to the perforated edge of the bonding flange only. Now install the Schlüter- KERDI collar by embedding it with a full overlap on the Schlüter-DITRA 25 mat. The Schlüter-KERDI collar is best adhered with the sealing adhesive Schlüter-KERDI-COLL.
5. Suitable covering materials include coatings or ceramic tiles. Adjust the height of the grate  by setting the height adjustment ring  and placing adhesive underneath it so that it is flush with the covering. Since the grate and frame assembly  has a smaller diameter than the bonding flange insert , the grate can be adjusted to match the joint pattern of the tile covering.
   Note: Schlüter-KERDI-DRAIN is also suitable for installation in wooden substrates. 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 for cleaning the drain body and the pipes.

Installation of Schlüter-KERDI-DRAIN-BASE

1. Place the drain body Schlüter-KERDI-DRAIN- BASE  on the support structure (using suitable impact insulation if applicable) and connect it to the drainage pipe. If necessary, use the supplied adapter for this purpose.
2. The screed must be installed in such a way that the trapezoid perforated flange of the Schlüter-KERDI-DRAIN bonding flange insert  is flush with the upper edge of the screed.
3. Attach a Schlüter-KERDI collar  with the sealing adhesive Schlüter-KERDICOLL to create a waterproof transition to the screed area. In a next step, install the bonded waterproofing assembly of Schlüter-KERDI or a trowel applied sealing compound with a sufficient overlap over the collar. If Schlüter-DITRA 25 is used for waterproofing, bring the mat all the way to the perforated edge of the insert only. Now install the Schlüter- KERDI collar by embedding it with a full overlap on the Schlüter-DITRA 25 mat. The Schlüter-KERDI collar is best adhered with the sealing adhesive Schlüter-KERDI-COLL. Follow the corresponding installation instructions if Schlüter-KERDI-DRAIN-BASE is installed together with Schlüter-KERDI-SHOWER.
4. Suitable covering materials include coatings or ceramic tiles (covering thicknesses 3-15 mm). Without using lubricants, adjust the height of the grate by pushing the stainless steel grate into place and placing enough mortar under it to align the grate 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 (if necessary, apply some lubricant to the O-ring).
   Note: Schlüter-KERDI-DRAIN-BASE is also suitable for installation in wooden substrates. Further details are available upon request.

Schlüter-KERDI-DRAIN-BASE 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 for cleaning the drain body and the pipes.

Installation of the Schlüter-KERDI-DRAIN combined floor drain

1. After the installation of impact or heat insulation, if applicable, position the combined floor drain  in accordance with the height of the floor assembly and connect it to the drainage system.
2. Now install the screed in such a way that the trapezoid perforated flange of the Schlüter-KERDI-DRAIN insert is flush with the upper edge of the screed.
3. Attach a Schlüter-KERDI collar  with the sealing adhesive Schlüter-KERDICOLL to create a waterproof transition to the screed. Next install the bonded waterproofing assembly made of Schlüter-KERDI or a trowel applied sealing compound with a sufficient overlap over the collar. If Schlüter-DITRA 25 is used for waterproofing, bring the mat all the way to the perforated edge of the drain only. Now install the Schlüter-KERDI collar by embedding it with a full overlap on the Schlüter-DITRA 25 mat. The Schlüter-KERDI collar is best adhered with the sealing adhesive Schlüter- KERDI-COLL.
4. Suitable covering materials include coatings or ceramic tiles.

Installation of the Schlüter-KERDI-DRAIN covering support

1. The installation of the covering can begin as soon as the Schlüter-KERDI collar has been adhered with the sealing adhesive Schlüter-KERDI-COLL. Suitable covering materials include ceramic tiles or natural stone.
2. Covering support assembly and height adjustment ring. Apply cementitious tile adhesive to the floor drain. Place the stainless steel frame with the drill holes into the recessed openings of the height adjustment ring and embed it in the tile adhesive. Covering support assembly and integrated odour trap. Place the stainless steel grate with frame into the bonding flange insert, fill tile adhesive under it, and then push to the maximum depth.
3. Using the spacer included, place this within the frame so that the adjacent tiles are correctly spaced to form the drainage openings. Note the tile should sit above the frame as indicated. Any excess adhesive must be wiped off after removing the spacer.
4. Place cementitious tile adhesive on the covering support and adhere it to the matching covering cutout of 8.2 x 8.2 cm to create a peripheral water drainage gap of at least 5 mm.

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

Installation of two level drainage with KD 10 MSB

Prior to installing the collar Schlüter-KERDI-DRAIN- MSB, remove the anti-flowback seal from the installed floor drain Schlüter- KERDI-DRAIN. This is done by loosening the three screws. Now place the O-ring  into the recess. You now can choose two different methods for connecting the waterproofing membrane:

1. Place the supplied EPDM connection collar  on the flange of the floor drain.
Note: There is no option to directly adhere the collar with a bitumen sheet. A suitable cold adhesive should be used to adhere a bitumen sheet.

Or:

2. Install the waterproofing membrane and cut out an opening that corresponds to the interior diameter of the connection collar.
Now place the stainless steel flange ring (top side is marked) on the collar with the recess openings matching the plastic pins of the flange. The stainless steel flange ring is then attached through the collar with the supplied screws. Firmly clamp the perforated inlet element  to the flange ring. Cut the Schlüter-KERDI-DRAIN insert to size in accordance with the height of the assembly and slide it over the perforated inlet element.

Note: In accordance with the applicable construction guidelines for flat roofs with continuous peripheral parapets, a safety spout must be installed for drainage.
Our stainless steel spout Schlüter-KERDI-DRAIN- SP-E is particularly suitable for this purpose.
