The Schluter®-KERDI-DRAIN-A adaptor kits are designed to convert clamping ring drains to integrated bonding flange drains when removal of the clamping ring drain is not practical (e.g., when they are set in concrete slabs). The adaptor kit includes a stainless steel adaptor ring, available in 5-1/4" (133 mm) and 7-1/2" (191 mm) diameter sizes, with an over-molded rubber gasket and a variety of perforated hole patterns that align with most common clamping ring drains. The adaptor ring replaces the clamping ring and is attached to the existing drain body using the clamping ring bolts. This connection is made watertight via the rubber gasket and Schluter®-KERDI-FIX adhesive/sealant. The adaptor drain with integrated bonding flange slides into the adaptor ring with the over-molded rubber gasket ensuring a watertight seal. Adaptor kits are suitable for both mortar beds and KERDI-SHOWER-T/-TS/-TT shower tray applications.

Grate assemblies consist of a frame, which can be seamlessly adjusted to the thickness and layout of the ceramic tile or stone covering via the height adjustment collar and lateral adjustment ring and grates or cleanout covers that are placed within the frame. The 4" (100 mm) standard grate assembly frame features an approximately 1/8" (3 mm) wide reveal after installation, and grate/frame combinations are available in stainless steel in CLASSIC design or anodized aluminum in CONTOUR design, both available in a variety of finishes. The 4"(100 mm) KERDI-DRAIN-STYLE grate assembly frame features a minimal reveal after installation. It is made of brushed stainless steel and can be combined with one of three grate design options: FLORAL (E), CURVE (F), or PURE (G). Various metallic and color-coated finishes are available. The 4" (100 mm) TILE grate is a square stainless steel plate with KERDI laminated on the surface to allow for bonding of ceramic or stone tile, which creates a virtually invisible drainage line. The 6" (150 mm) square and round stainless steel grate assembly frames feature an approximately 3/16" (5 mm) wide reveal after installation and can be combined with stainless steel grates in CLASSIC design or a square clean out cover.

Notes:

The 4" (100 mm) TILE grate and the 6" (150 mm) square and round grates and clean out cover are not compatible with the 5-1/4" (133 mm) adaptor kits.

The 6" (150 mm) grate assemblies and grate assemblies used with the 5-1/4" (133 mm) adaptor kits only allow vertical and tilt adjustment (no lateral adjustment).

Schluter-KERDI-DRAIN-A requires no special maintenance and is resistant to mold and fungi. The grates may be removed to clean the drain housing and the drain pipes. Clean the grates using common household cleaning agents. Stainless steel grates 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. Stainless steel surfaces develop a sheen when treated with a chrome-polishing agent. Do not use abrasive or alkaline cleaning agents.

Installation instructions for the use of KERDI-DRAIN-A in shower applications can be found in the Schluter®-Shower System Installation Handbook.

If a clamping ring drain is installed, replace with KERDI-DRAIN or convert using the KERDI-DRAIN adaptor kit.

1. If using the KERDI-DRAIN adaptor kit, remove the clamping ring from the installed drain and save the bolts for installation of the adaptor ring. Align the bolt pattern of the clamping ring with the matching punch-outs in the adaptor ring. Punch the matching inserts out through the stainless-steel adaptor ring. 2. Apply a continuous 1/4" - 3/8" (6 - 10 mm) bead of KERDI-FIX to the underside of the adaptor ring. Align the holes in the adaptor ring with the bolt holes in the installed drain and place the adaptor ring on the installed drain flange. Re-insert and tighten the bolts using a star pattern. Bolts are to be finger-tight plus 1/4 turn; do not overtighten, as this may warp the adaptor ring and result in leaks. 3. Slide the adaptor flange into the adaptor ring and ensure full support under the adaptor flange with mortar or the detachable center section of the foam tray. For a mortar bed, the screed is then placed flush with the top of the bonding flange of the KERDI-DRAIN. Slope the mortar bed using the bonding flange and mortar screeds as guides. For installation of a shower tray, depending on the installed drain elevation, it may be necessary to install a polystyrene foam panel, backerboard, etc. Install the tray as per the instructions in the Schluter®-Shower System Installation Handbook.  Note: Schluter®-Systems strongly recommends a leak test be performed on the connection between the drain and waste line prior to continuing on with the remainder of the installation whenever possible. Refer to local plumbing and/or building codes for any specific requirements in your area.
