FLOOR DRAINS

the integrated bonding flange with KERDI-
FIX adhesive/sealant. The stainless steel
bonding flange must be clean and free
of grease or other contaminants prior to
KERDI-FIX application.
3. Embed a 20" x 20" (50 x 50 cm) cut
section of KERDI in the bond coat and
work the membrane onto the KERDI-
DRAIN bonding flange and surrounding
membrane to ensure full coverage
and remove air pockets. The KERDI is
carried to the step in the bonding flange
(template provided) and must overlap
the DITRA or DITRA-XL membrane by a
minimum of 2" (50 mm).
Grate assembly
Grate
1. The grate assembly is installed in
conjunction with the tile. Place the
height adjustment collar inside the lateral
adjustment ring and snap the grate
frame into place.
Note: For drains with 6" (150 mm)
grates, the height adjustment collar
is integrated with the grate. For the
residential adaptor kit, there is no lateral
adjustment ring.
2. Fill the step in the bonding flange with
Schluter SET™, Schluter ALL-SET™,
Schluter FAST-SET™ or unmodified
thin-set mortar and back-butter the
underside of the grate frame to ensure
full support. Press the assembly into the
mortar and install the surrounding tiles,
ensuring full coverage.
3. Position the grate to match the joint
pattern of the tile covering and press
flush with the tile surface. Remove all
excess setting material.
Note: Protect the visible surface of the
grate from contact with setting and grouting
materials. In particular, anodized aluminum is
sensitive to alkaline materials.
Tileable Covering Support
1. The covering support is installed in
conjunction with the tile. Place the tile
spacer inside the lateral adjustment ring.
2. Fill the step in the bonding flange with
thin-set mortar and press the assembly
into the mortar. Install the surrounding
tiles up to the tile spacer using Schluter
SET™, Schluter ALL-SET™, Schluter
FAST-SET™ or unmodified thin-set
mortar, ensuring full coverage. Set the
tile to the integrated tabs on the lateral
adjustment ring, which provide for a
flush transition to the covering support.
Remove all excess setting material.
Position the tile spacer to match the
joint pattern of the tile covering.
3. Apply tile to the top of the covering
support using Schluter SET™, Schluter
ALL-SET™, Schluter FAST-SET™ or
unmodified thin-set mortar. The tile
is installed flush with all sides of the
covering support to provide the drainage
openings.
4. Once the assembly has been set
and grouted, remove the tile spacer
and insert the tiled covering support
in the lateral adjustment ring.
Note: For acid-resistant coverings, use
an epoxy adhesive to set and grout the
tile.
KERDI-LINE
Preparation
When installing KERDI-LINE against a wall,
be sure to factor in wall board thickness
before cutting the hole in the substrate.
1. Any leveling of the floor must be done
prior to the installation of the channel
body. For installation adjacent to the
wall, the channel body must be aligned
in accordance with the thickness of
the wall covering. For intermediate
installation, use the supplied filling strip
with peel-and-stick adhesive layer to
make the channel support symmetrical.
2. KERDI-LINE can be installed in
conjunction with the provided
channel support as described below
or set in loose mortar. KERDI-LINE
is connected to the waste line with
the appropriate mechanical no-hub
coupling in accordance with the coupling
manufacturer’s instructions.
Channel body installation
Access to plumbing from below
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.
1. Apply Schluter SET™, Schluter ALL-
SET™, Schluter FAST-SET™ or
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.
2. Apply Schluter SET™, Schluter ALL-
SET™, Schluter FAST-SET™ or
unmodified thin-set mortar to the top
of the channel support with a notched
trowel 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.
No access to plumbing from below
When there is no access to the plumbing from
below, the channel body must be set and
connected to the waste line simultaneously.
1. 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.
2. Apply Schluter SET™, Schluter ALL-
SET™, Schluter FAST-SET™ or
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.
3. Apply Schluter SET™, Schluter ALL-
SET™, Schluter FAST-SET™ or
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.
4. 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.
5. The screed is then placed flush with the
top of the bonding flange of the KERDI-
LINE. Slope the mortar bed using the
bonding flange and mortar screeds as
guides.
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.
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.
Connection to waterproofing
membranes
The KERDI or DITRA waterproofing
membranes can be installed as soon as the
mortar bed can be walked upon.
1. KERDI, DITRA or DITRA-XL is installed
up to the outer edge of the KERDI-LINE
bonding flange using Schluter SET™,
Schluter ALL-SET™, Schluter FAST-
SET™ or unmodified thin-set mortar.
