FLOOR DRAINS

5 mm) V-notched trowel or the DITRA-

TROWEL, which features an 11/64" x

11/64" (4.5 x 4.5 mm) square-notched

design. Solidly embed the matting into the

bond coat using a float, screed trowel, or

DITRA-ROLLER.

2. Apply Schluter SET

, Schluter ALL-SET

Schluter FAST-SET

or unmodified thin-

set mortar to the membrane surrounding

KERDI-LINE with a 1/4" x 3/16" (6 x 5 mm)

V-notched trowel or the KERDI-TROWEL,

which features a 1/8" x 1/8" (3 x 3 mm)

square-notched design. Embed the KERDI

collar in the bond coat to ensure full

coverage and remove air pockets.

Grate assembly

Grate

1. Apply Schluter SET

, Schluter ALL-SET

Schluter FAST-SET

or unmodified thin-set

mortar to the underside of the grate frame

and place it in the channel body ensuring

full coverage and support of the frame.

Insert the foam spacers in the grate frame

to reinforce it during the remainder of the

installation.

Note: The tape on the grate frame does

not need to be removed. It is intended

to help keep setting material out of the

channel body during installation.

2. Slide the plastic height adjustment spacers

with threaded bolts onto the tabs along

the inside of the grate frame to adjust the

elevation of the frame. The spacers may

be adjusted simply by turning the bolts by

hand. The elevation should be set such

that the frame will be flush with the surface

of the tile covering.

3. Apply Schluter SET

, Schluter ALL-SET

Schluter FAST-SET

or unmodified thin-

set mortar to the substrate and install the

tiles, ensuring full coverage. Once the tile

covering is set and grouted, remove the

spacers from the grate frame and insert the

grate.

Note: Protect the visible surfaces of the

grate frame and grate from contact with

setting and grouting materials. Setting

and grouting materials must be removed

immediately.

KERDI-LINE-FC

1. Install KERDI-LINE channel bodies end-

to-end and overlap the KERDI collars

using Schluter SET

, Schluter ALL-SET

Schluter FAST-SET

or unmodified thin-set

mortar to ensure a waterproof connection.

KERDI-LINE-FC is subsequently installed

in conjunction with the KERDI-LINE grate

assembly and adjacent tiles.

Note: KERDI-LINE-FC may be used with

tiles that are 1/4" (6 mm) thick or greater.

2. Apply a sufficient amount of thin-set mortar

to the substrate and/or the back of KERDI-

LINE-FC and press the profile into the

mortar until its surface is flush with the

adjacent tile and grate assembly.

3. Leave a space of approximately 1/16" –

1/8" (1.5 – 3 mm).

4. Fill the joints completely with grout or

setting material.

Tileable Covering Support

Wall Installation

1. Peel protective foil off the cover strip and

adhere the strip to the bonding flange

adjacent to the wall(s). Position the strip

along the edge of the channel. The cover

strip hides and protects the KERDI surface

under the tile.

2. Insert the tile spacers into the channel body.

Install the surrounding tile on the adjoining

walls and mortar bed up to the spacers

using Schluter SET

, Schluter ALL-SET

Schluter FAST-SET

or unmodified thin-set

mortar, ensuring full coverage. Remove all

excess setting material.

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

the front side of the covering support

to provide the drainage opening and

overhanging the back side of the covering

support to cover the bonding flange along

the wall. Measure and cut the tile such that

an approximate 1/16" (1 mm) gap is left

at the wall. When the ends of the channel

body are located adjacent to walls, the

tile is installed overhanging the end of the

plate to cover the bonding flange along the

walls. Measure and cut the tile such that an

approximate 1/16" (1 mm) gap is left at the

walls.

Note: When the mortar bed is tiled beyond

the ends of the channel, the tile on the

ends of the covering support can be cut

to either match the grout joints of the

surrounding floor covering or to provide a

perimeter drainage opening.

Intermediate Installation

1. When the ends of the channel body are

located adjacent to walls, peel protective

foil off the cover strip and adhere the strip

to the bonding flange adjacent to the walls.

Position the strip along the edge of the

channel. The cover strip hides and protects

the KERDI surface under the tile. When the

mortar bed will be tiled beyond the ends of

the channel, the cover strip is not required.

2. Insert the tile spacers into the channel

body. Install the surrounding tile on the

adjoining walls (if applicable) and mortar

bed up to the spacers using Schluter SET

Schluter ALL-SET

, Schluter FAST-SET

or unmodified thin-set mortar, ensuring

full coverage. Remove all excess setting

material.

3. Apply tile to the top of the covering support

using thin-set mortar. The tile is installed

flush with the front and back of the covering

support to provide the drainage openings.

When the ends of the channel body are

located adjacent to walls, the tile is installed

overhanging the end of the plate to cover

the bonding flange along the wall. Measure

and cut the tile such that an approximate

1/16" (1 mm) gap is left at the wall.

Note: When the mortar bed is tiled beyond

the ends of the channel, the tile on the

ends of the covering support can be cut

to either match the grout joints of the

surrounding floor covering or to provide

perimeter drainage openings.

Note: For acid-resistant coverings, use an

epoxy adhesive to set and grout the tile.

Maintenance

KERDI-DRAIN and KERDI-LINE require no

special maintenance and are resistant to mold

and fungi. The grate may be removed to clean

the drain housing and the drain pipes.

Clean the grates and profiles using neutral

cleaners. Avoid the use of strong acids (e.g.,

hydrochloric, hydrofluoric) and bases/alkaline

cleaners (e.g., bleach, ammonia, chlorides).

Do not use abrasive cleaning agents and tools.

Even stainless steel requires periodic cleaning,

which will maintain a neat appearance and

reduce the risk of corrosion. Stainless steel

surfaces develop a sheen when treated with a

chrome-polishing agent.
