thinset to initially cure without being disturbed (e.g. tile boxes). Make sure the floor waste pipe is centered within the wedi
drain unit and remains there until the drain connection is completed.
12. Apply wedi provided safe Lubricant to the Rubber Sealing Gasket and insert the Rubber Sealing Gasket between the wedi Drain
Unit‘s interior and the outside of the 2 in. waste pipe in the floor. Push the Rubber Sealing Gasket down along the waste pipe
until it is stopped by the Drain Unit‘s lower interior flange.

13. Using a sharp utility knife cut the Compression Spacer into two halves along the pre-made cut lines/notches. This will allow
you to insert both halves through the the narrow drain opening. Apply wedi provided safe Lubricant to the rubber part of the
Compression Spacer halves.
14. Insert the first and then the second half of the Compression Spacer in between Drain unit and waste pipe. They will both
rest tightly on top of the Rubber Sealing gasket after they will push it into final resting position. The Compression Spacer’s
rubberized part will not always sit flush with the floor waste pipe’s edge, which is due to the thinset thickness tolerances under
the shower base. Note: The rubberized part of the Compression Spacer is not part of the wedi drain’s waterproofing design – it
is used solely to keep all dirt out of the drain connections.
15. Insert the Locking Nut with notched side up into the threaded part of the Drain Unit opening and screw down until Locking
Nut top is flush with top edge of Drain Unit‘s threaded part. Important: Turn Locking Nut to LEFT to insert and screw
into flush position.
16. Insert Strainer Key into Locking Nut at notch connections and with Strainer Key printed side up. The Strainer Key is used as a
tool to tighten the compression seal of the Drain Unit, but remains in place later to serve as a hair catcher to protect the drain
and make maintenance and cleaning easy.

17. Insert a flat headed screwdriver into Strainer Key slit and turn LEFT to tighten the compression seal (turn Counter-Clockwise).
Achieve a hand-tight fit and do not over-tighten.
18. Clean the perimeter channels from dust or any other contaminants. Set up a continuous 1/2 in. bead of wedi Joint Sealant
along the Riolito‘s channel on the outer perimeter and only in areas where you can immediately install a building panel into
the fresh sealant.
19. Push the wedi building panel fully into the channel of the shower base, being sure the bead of sealant is fully compressed.
Smooth out any pushed out sealant on inside seam using a putty knife. Fasten the panels directly to the studs starting 1 ft
above the base and in corners while keeping the board pushed down into the channel, and set the wedi fasteners with wedi
washers at a rate of 1 fastener per 1 ft. On every framing stud, one fastener has to be installed through the seam between two
adjoining building panels to create a smooth transition. wedi requires wedi building panels to be installed in all areas exposed
to water and never lower than 6 inches above the highest wall-mounted shower fixture.
20. Apply continuous 1/2 in. beads of sealant between all connections of panels and install with tightly butted seams. Excess sealant
must be spread flat with a putty knife. All seams and fastener heads in the assembly are covered with a topical 1/2 inch bead
of sealant and spread flat. The seams should be covered 1 in. on either side of a seam. All fastener / washers are covered with
sealant stretching 1 in. over the washer edges.
