Fill half the bath with water and check whether the bath is still horizontal. This is necessary. Use the adjustable legs
=
for correction. Check whether the drain pipeline connection is watertight and then fill up the bath up to the overflow
outlet. Allow it to overflow and check the sealing and proper drainage of water via the overflow connection.
The open sides of the bath may be finished with plastic panels or with a tile wall. This may be done for the entire rim, or

only in certain sections.
For sealing the bath joints, only use acid-free silicon sealant suitable for plumbing applications.

The bath may be placed in several ways:
=
- The bath may be placed against the tiles of the wall. Apply silicon sealant all around the rim to absorb the
movements of the bath if any. This 4 to 5 mm a space is required to absorb the torsional forces acting on the
rim of the bath
- When the bath is finished with a wall on the underside instead of a acrylic panel, there should be a joint
between the top of the wall or row of tiles and the bottom of the bath of 4-5mm. This joint must also be sealed
with silicon.
The silicon sealant provides a good watertight finishing join and allows the bath to expand to some extent. It is
also necessary to fill the bath with water up to the overflow rim and to ensure that the bath is resting properly on all
its legs before you start sealing.

Ventilation grid

In order to ensure optimum operation of the motor(s), it is necessary to install
under the bath. This grid must be splash-proof and placed so that splashing water does not find its way under the bath. The
minimum effective flow surface of the grid must be 100cm² for each Hydro or Aero system and 200cm² for combined
systems Hydro/Aero and should not vent in places where the temperature is less than +15°C and more than +35°C. (See
