-KERDI-LINE channel body installation
Plumbing Access: When there is access to the plumbing from below and the waste line can be connected after installing KERDI-LINE, the channel body
may be set without making a connection to the waste line simultaneously.
Apply unmodified thin-set mortar to the
substrate where the drain is to be placed
with a notched trowel and solidly embed the
channel support in the mortar.
1
Apply unmodified thin-set mortar to the
top of the channel support and press the
channel body firmly into the mortar, ensuring
full support of the bonding flange. Check to
make sure the KERDI-LINE is level.
2
No Plumbing Access: When there is no access to the plumbing from below, the channel body must be set and connected to the waste line simultaneously.
Begin the drain installation by dry fitting the
components. Measure and cut a section of
pipe to connect the coupling to the odor trap
below the floor, using the channel support
as a spacer.
1
Apply unmodified thin-set mortar to the
top of the channel support with a notched
trowel and press the channel support firmly
onto the underside of the channel body.
Attach the mechanical coupling to the drain
outlet and the cut section of the pipe per the
coupling manufacturer’s instructions.
2
Apply unmodified thin-set mortar to the
substrate where the drain is to be placed
with a notched trowel. Prepare the cut
section of pipe and odor trap with cleaner,
primer and ABS or PVC cement per the
solvent cement manufacturer’s instructions.
3
Solidly embed the channel support and KERDI-LINE into the mortar on the floor and connect the
cut section of pipe to the odor trap. Check to make sure the KERDI-LINE is level.
Note: KERDI-FIX or other adhesives that are compatible with EPS foam can be used to install the
channel support and channel body as an alternative to thin-set mortar. Apply a generous bead of
KERDI-FIX to the top and bottom of the channel support. The use of KERDI-FIX limits the ability
to level KERDI-LINE.
4
Clamping Ring Drain Installed: If a clamping ring drain is already installed, the drain must be replaced with KERDI-LINE.
Preparation
Locate and cut a hole in the substrate for the drain outlet and coupling to the waste line using the template
provided. Limit the diameter of the hole to 5" (125 mm) maximum to ensure proper support for the tile assembly.
Note: Fill in box-outs in concrete floors with dry-pack mortar or concrete. A pipe coupling or similar can be used
as a form around the waste line.
Note: Schluter

-Systems 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.
