INSTALLATION — Shower base with Schluter
®
-KERDI-DRAIN 23
Remove the clamping ring from the installed
drain and save the bolts. Align the bolt
pattern of the clamping ring with the adaptor
ring and punch the matching inserts through
the adaptor ring.
1
Apply a 1/4" - 3/8" (6 mm - 10 mm) bead
of KERDI-FIX to the installed drain flange.
Place the adaptor ring on the installed drain,
re-insert the bolts, and tighten evenly. Make
bolts finger-tight plus 1/4 turn; over tightening
may warp the ring and result in leaks.
2
Slide the adaptor flange into the adaptor
ring and ensure full support underneath with
mortar or the detachable center section of
the foam tray. Depending on the installed
drain elevation, it may be necessary to install
a polystyrene foam panel, tile backerboard,
etc. prior to the tray. Install the tray as per the
instructions on page 22.

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

-KERDI-DRAIN with mortar bed
Plumbing Access: If there is access to the plumbing from below and the waste line can be connected after installing KERDI-DRAIN, the drain can be
installed in conjunction with the mortar bed.
No Plumbing Access: When there is no access to the plumbing from below, KERDI-DRAIN is installed to the appropriate height and connected to the
waste line prior to the installation of the shower base.
Measure and cut a section of pipe to connect KERDI-DRAIN to the odor trap using the
foam spacers included with the drain as a spacer. When installing KERDI-DRAIN over wood
substrates, the minimum thickness of mortar required at the perimeter of the bonding flange is
1" (25 mm). Prepare the odor trap, cut section of pipe, and KERDI-DRAIN with cleaner, primer and
ABS or PVC cement per the solvent cement manufacturer’s instructions and connect.
1
Pack loose mortar under the drain up to
the inlet hole to ensure solid and uniform
support of the bonding flange and level. The
mortar bed is then placed according to the
instructions above.
2
Place a ring of loose mortar up to the inlet hole in the floor and firmly press the drain into the mortar
and level. The bonding flange must be fully supported to prevent damage to the tile assembly
(e.g., cracked grout around drain). When installing KERDI-DRAIN over wood substrates, the
minimum thickness of mortar required at the perimeter of the bonding flange is 1" (25 mm).
1
The screed is then placed flush with the top
of the bonding flange of the KERDI-DRAIN.
Slope the mortar bed at 1/4" (6 mm) per
12" (305 mm) using the bonding flange and
a perimeter screed as guides.

-Systems strongly recommends a leak test be performed on the connection between
the drain and the waste line prior to continuing with the remainder of the installation whenever possible.
Refer to local plumbing and/or building codes for any specific requirements in your area.
