Additionally, the electrical installation must be equipped with a circuit breaker to ensure the
all-pole disconnection from the power supply.
A voltage equalisation connection must be established between the metal elements of the
bathtub, following the appropriate regulations in each country. Parts with live components,
except for those operating at a protective extra-low voltage not exceeding 12 V, must be
inaccessible to the person in the bathtub. Electrical components must be positioned or secured
in a way that prevents them from falling into the bathtub.
As soon as the water inlet is below the tub's rim, a connection must be established with a safety
device in accordance with EN 1717 (Fluid category 5). For instance, this may involve employing a
DC safety device (e.g., a type 1 pipe-interrupter with a permanent connection to the atmosphere)
based on the specific installation requirements. This connection must be carried out exclusively
by a qualified specialist. These guidelines apply to the following scenarios:
A. All tubs that are filled through the overflow.
B. All tubs that are connected and filled through the nozzles of the water massage in the
existing T fitting.
In both cases, the connection must be made using reinforced elastic tubing capable of carrying
premixed hot and cold water.
Flow rate: Maximum 20 litres/min (EN 200)
Overflow capacity: Minimum 36 litres/min (EN 274)
Drainage capacity: Minimum 48 litres/min (EN 274)
Permanent installation
Maintenance hatches should be provided with dimensions of at least 50 x 50 cm, ensuring
accessibility to technical components such as the pump, blower, valves, connection box, and
other connections. Preferably, employ removable side panels, but always prioritise rigid
elements.
Additionally, it is recommended to install 20 x 20 cm maintenance hatches for drainage/overflow,
ensuring proper noise insulation during installation.
For proper ventilation, the installation of a ventilation grill (not supplied) is absolutely necessary.
Depending on the bathtub model, position the ventilation grill in the wall lining near the units.
Inside the hatch, a ventilation grid (minimum 150 cm) can be fitted to supply air to the blower.
Alternatively, consider placing a maintenance hatch/ventilation grid in the adjacent room.
