INSTALLATION SEQUENCE continued
• Picture 4-5: the bathtub is leveled via a water level at the intended local installation area.
• Picture 6: place the bathtub by raising it up 3½” with 4x4 peices of lumber so you can have access from the bottom of
the bathtub. Important note: during the installation, the bathtub should not be turned on its side to prevent its weight
from deflecting its monobloc sides. This is why it is important to use supports to raise the bathtub above the floor.
This will also provide you with easy access to the internal plumbing parts.
• Picture 7: the monobloc sides of the bathtub touching the floor should be marked. The panel supporting brackets should
be taken inside as much as the thickness of the acrylic panel allows and be fixed with silicone to the floor. The panel
supporting brackets are mounted to the bathtub feet to support the decorative front panel in case of unexpected lateral
forces.
• Picture 8: the water outlet pipe should be connected.
• Picture 9: foot leveling lock nuts are adjusted.
• Picture 10: silicone is applied to the feet of the bathtub that stands on the floor.
• Picture 11: when the installation is completed, the bathtub is taken down fromn the supports ( ie 2 x 4x4's).
If necessary, installation is completd by applyingsilicone at several points between the bottom panel and floor.
• Picture 12: any remaining protective packaging should be removed only after the bathtub installation and other
construction work in the bathroom is fully finished.

Deep Immersion Feature
The new Aquatica overflow system used in Harmony series bathtubs allows to
adjust the water level trough the bath handle. The ability to increase the water
level is achieved by adjusting the handle position during the installation.
The max level of the water level can be achieved by adjusting the handle upwards
(Fig. b). The lowest water level is with the handle downward (Fig. a).
The new Aquatica overflow system used in Harmony series bathtubs is the result of the combination of two elements:
handle and overflow.
This system allows the waste plug opening and closing and offers the possibility to adjust the overflowing level in
bathtubs.
