Install The Waterproofing Membrane Or Compound; Install The Suction Bushing; Install The Cement Board - Kohler K-1000-H2 Guide D'installation

9. Install the Waterproofing Membrane or Compound
WARNING: Risk of property damage and concealed leakage. To achieve a watertight installation,
it is critical that you install the waterproofing membrane or applied compound according to the
material manufacturer's instructions. Kohler Co. will not be liable for damage caused by
waterproofing materials that are improperly installed or sealed.
NOTE: The waterproofing membrane or applied compound and the cement board can be installed in the
order you prefer, as long as they are installed exactly as directed. Follow all manufacturer's instructions.
Install a waterproofing membrane or applied compound to the entire floor and wall surfaces (up to
the ceiling).
Although some membranes can be installed directly to the stud framing, we suggest you install a
plywood backing behind the membrane to at least the height of the basin threshold.

10. Install the Suction Bushing

Use a 3-1/4" hole saw to carefully cut a hole in the waterproofing membrane and plywood backing
at the suction inlet location.
Press the flat rubber gasket fully into the suction housing inlet.
Apply silicone sealant to the bushing flange surface and insert the bushing through the suction hole.
Partially thread the nut to the bushing. Do not tighten.
Apply silicone sealant to the end threads of the bushing and carefully thread the bushing to the
housing until hand tight.
Wrench tighten an additional 1/4 turn. Do not overtighten.
Wrench tighten the nut against the plywood backing. Do not overtighten.
Remove any excess sealant.
Insert the small screw (packed with the literature) through the hole in the nut and secure. This will
help prevent any movement of the nut over time.

11. Install the Cement Board

Install cement board to the walls according to established installation methods. The cement board
must cover the entire wall surface from the ceiling to the subfloor. Provide a cut-out area around the
mounting frame.
Mark the cement board for the suction fitting hole by first measuring up at least 2-1/2" (6.4 cm)
from the footbath basin material. Add the thickness of the floor material you plan to use and draw a
pencil mark at that location.
