Installation Guide

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 under the adaptor
flange with mortar. The mortar bed is then
placed according to the instructions on
page 23.

Clamping Ring Drain Installed: If a clamping ring drain is installed, replace with KERDI-DRAIN or convert using the KERDI-DRAIN adaptor kit.
If necessary, cut the KERDI-BOARD-SC to length using a utility knife and KERDI-SHOWER-SC/-SR using a handsaw.

Check the underside of the curb or ramp
to ensure that full coverage and support
is achieved. Note: When setting tile on the
curb, the surface must be sloped towards
the shower drain.
Press the bench firmly into place and check
the underside and backsides to ensure that

to cover all seams and corners, ensuring a
minimum 2" (50 mm) overlap, and work the

-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.
