In-Ground Spas - BWT Spas ST 2.18 Notice D'installation Et Conseils D'utilisation

Regulations concerning electrical safety volumes must be respected (see the safety notice at the beginning
of this document).

3.2.2 In-ground spas

Leave a gap of at least 80 cm around the entire periphery of the spa to facilitate access to the spa
components.
IMPORTANT
The spa should not hang from the lip of the spa shell, it should rest on its timber frame on the
floor of the excavation.
The floor of the excavation should be stable and perfectly flat (check using a spirit level) and able to bear
the total weight of the spa (plus water, plus occupants) with deforming over time.
If necessary, wedges may be inserted under support structure and spa to ensure that it is perfectly level
and that water level is constant at every point.

Using a spirit level, check that the timber support structure is vertical, then fasten the bottom of the structure
to the ground using Ø 8 mm lag screws.
The spa pack mounting plate must be perfectly vertical to ensure that it will line up correctly with the spa
pack to facilitate connections. Otherwise, assembly may be difficult and the connections could leak.
If wedges were inserted under the spa, insert wedges of a similar height under the spa pack mounting
plate to ensure coherency.
COMPLIANT
It should be noted that the spa pack's vibration damping feet allow the spa pack height to be adjusted
within 8mm.
The decking support system should take into account that all 4 sides of the spa must be accessible to allow
maintenance.
Create one or more access hatches in the decking that are easy to open and large enough to allow
unhindered access to the spa components (alternatively, access hatches can be made in the façade
covering a side of the spa that is accessible).
