Primo Base and wedi Fundo

Shower Kit - Primo Installation Manual

1. Cut the 2 inch waste pipe even and flush with the subfloor surface. Make sure that the cut out fits to the Fundo base‘s drain.

Cut out a 5 in. diameter hole around the 2 in. pipe‘s center to allow for the wedi drain to be inserted into the subfloor while

the cut out area must remain free of deflection. The drain waste pipe and P-trap have to be safely affixed to and supported

by the subfloor structure.

2. Cut the Fundo base to fit between framed walls and so its wedi drain unit can connect with the floor waste pipe. Consider also

the space needed by a curb or extension before cutting your wedi base. Consider that cutting the base may change the slope

design and tile layouts should be considered before cutting. Consider that enough material thickness remains available to later

remake the 1/2 in. x 1/2 in. perimeter channel whereby the bottom of the channel must not be thinner than 1/4 in. Do not cut

close to the integrated drain and maintain a minimum distance of 2 in. from the drain opening. It is recommended to turn the

base on its back so you can move the circular saw over a flat surface ensuring a square cut.

3. Once cut, dry fit the base and then remake the 1/2 in. × 1/2 in. perimeter channel where the base connects to wedi Building

Panels, curbs, ramps or extensions. Clean the base and channels from saw dust using a vacuum cleaner.

4. Next, install the Fundo Click and Seal

™

drain unit. Drain components are delivered inserted inside the Drain Body. Please take

the parts out and use step by step following our manual here.

5. Apply the wedi provided safe lubricant to the black rubber ring inside the wedi Drain Body.

6. Insert the Drain Body snugly into the receiving mechanism of the Drain Unit on the underside of the Fundo base.

7. Once inserted, turn the Drain Body clockwise until its plastic flap clicks in position in its final resting position. This will require no

more than a quarter turn. Ensure a tight connection by pushing and pulling on the Drain Body and verifying a flat seat relative

to the shower base surface. If you ever want to remove the Drain Body from a locked position, use a flat head screwdriver to

push the snap mechanism’s plastic flap inwards while unscrewing the Drain Body counter-clockwise (LEFT) at the same time.

In case it is difficult to hear the click mechanism, you can also verify a safe connection as described under point 8.

8. On the top side of the drain you can verify the drain unit has successfully connected when the single hash marks are centered

between the double hash marks.

9. Clean the subfloor with a moist sponge to remove dust and dirt, and apply a skimcoat of a suitable, modified tile adhesive/

thinset (ANSI 118.4 or better), and comb through with a 1/4 in. × 1/4 in. notched trowel. Notches should be applied

uniformly and point towards the shortest side of the base area. You can also use a 1/2 in. square notch trowel, instead.

10. Trowel the thinset on the rear side of the Fundo again using a 1/4 in. × 1/4 in. notched trowel. Apply a skimcoat of tile

adhesive over the entire product‘s cement surface, then comb through thinset bed creating channels pointing in same

direction as applied on subfloor.

11. Press the Fundo firmly into the thinset bed (sloped side up) ensuring that the installation is level along its perimeter and sides,

and thinset attachment and coverage is void free. Apply some weight equally and leave on surface and drain area to allow

the 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.
