14. Construct the Finished Basin, Wall and Ceiling
DANGER: Risk of death or serious injury.
Gaps between the suction cover and the finished basin
material present a serious hair entrapment hazard which could trap the bather under water. The
finished basin material must be constructed so the suction cover installs against a flat, smooth surface.
Carefully repair or seal all gaps.
NOTE:
Refer to the Design Guide section of this manual for finished basin and wall material
recommendations and information.
Install the finished basin, walls and ceiling materials according to established installation methods.
For the suction assembly and K-7179 drain, the wall must be 3/4
″
(2cm) to 1-3/4
″
(4.4cm) thick. The
total thickness of the basin (basin material and finished floor material combined) must not exceed
1-1/4
″
(3.2cm) at the drain. Refer to the instructions packed with the drain for specific details.
Cut or drill holes for the tower, water supplies, suction, drain and drain overflow, as well as any
light fixtures or other accessories.
Finish the basin wall surface so it is perfectly flat and smooth within the 5
″
(12.7cm) diameter area
around the suction hole.
15. Install the Suction Assembly
Apply a thin bead of clear, high-quality silicone sealant around the flange rim and on the threads.
Insert the flange into the bushing and thread securely.
Remove any excess sealant.
Install the suction cover to the flange with the suction cover screw. Orient the plastic cover (if used)
with the solid section of the cover on top and the holes down. Use a screwdriver to tighten the
suction cover screw until tight. Do not overtighten.
Make sure all suction cover holes are clear and unobstructed to maximize performance. Press the
plug button (plastic suction covers only) in place over the screw head.
Permanently secure the suction bracket and pump box to the wall and floor, if desired.
Allow the sealant to fully cure.
