ASSEMBLE DRAIN:

(A) Insert threaded drain tube down through hole in trough.

(B) Place the down tube with rubber gasket under the trough and screw onto the threaded drain tube. Use the red down tube installation tightening tool to tighten from the top.

(C) Leave the red tightening tool in place until mud work is complete.

(D) Cut the existing 2” drain pipe flush to the existing floor.

(E) Install the round center support disk over the 2” pipe hole. Center the support disk over the pipe. Fasten to the subfloor with screws using pre-drilled holes.

(F) Install peel-and-stick supports on the bottom of the trough 1 1/2” in from both ends. Add a dab of ARDEX TLT^TM 700 if necessary.

MIX DECK MUD ACCORDING TO MANUFACTURER'S INSTRUCTIONS INSTALL LINEAR DRAIN:

(A) Insert the linear drain trough into the 2” pipe. Make sure the trough is level in both directions.

(B) Install Blue Tape around the perimeter of the trough flange to protect.

(C) Pack deck mud (like ARDEX A 38^TM Rapid Set Screed) under the trough to confirm it is well-supported and check for level.

INSTALL MUD AND SCREED:

(A) Using the top of the flange, screed mud (ARDEX A 38^TM Rapid Set Screed) flush with the flange of the trough to the desired thickness, ensuring a 1/4” slope per foot.

• Let the mud set up and cure.

INSTALLING ARDEX TLT^TM 716 WATERPROOFING MEMBRANE:

• Make sure the surface of the mud bed is flat and smooth.
• Mix up appropriate ARDEX tile mortar to high water range.
• Measure and cut ARDEX TLTTM 716 Waterproofing Membrane to the appropriate size.

(A) Trowel the ARDEX mortar onto the cured mud bed with a 1/4” x 3/16” V-notch trowel.

(B) Remove blue tape from the perimeter of the flange.

(C) Install a bead of ARDEX TLT^TM 700 on top of the trough flange perimeter.

(D) Place the ARDEX TLT^TM sheet membrane over the troweled mortar and over the linear drain.

(E) Use the flat side of a trowel or a drywall mud tool to flatten the membrane and remove any air pockets.

(F) Use a utility knife and cut inside the trough around the inside perimeter. Discard the cut-out piece of ARDEX TLT^TM 716.

INSTALLING DRAIN GRATE:

(A) Using the red tightening tool, loosen and back out (remove) the threaded down tube. Place the appropriate self-adhesive adjustment spacers into the trough. Dry fit the grate cradle and adjust spacers to get the appropriate height according to the tile thickness.

(B) Once the height and spacers are set, screw the threaded drain tube through the grate cradle and trough and tighten down firmly.

(C) Remove the red tightening tool and install the strainer.

(D) Install the drain grate using the appropriate drain grate supporting clips.
