REQUIREMENTS FOR INSTALLING THE PRODUCT
Pay ATTENTION to the dimensions of the packages of the purchased product!
Check the route for transporting the product, to the selected installation site, checking the measurements of: doors, stairs, landings, corridors
Installation must be carried out by qualifi ed personnel in accordance with IEC standards.
The installer must make sure in advance that the fl oor and/or wall where the product will be installed is suffi ciently level, capable of supporting the weight
(min 200 Kg/m2) and that there are the necessary technical arrangements.
He must also check that the surfaces next to which the product will be installed are tiled suitably for the selected product and that they do not feature
any elements which might obstruct the installation (e.g. unevenness, protruding tiles, out-of-line, etc.)
Before carrying out the electrical and hydraulic connection to the appliance, the installer must ask the user to provide the declaration of conformity of
the building's systems, which is required by law.
ATTENTION: If this document is not produced, the manufacturer declines any liability for the systems or rooms designed to host its appliances.
The installation of electrical and plumbing devices (sockets, switches, lamps, etc.) inside the bathroom, must comply with provisions currently regulating
the matter in the country in which the device will be installed, and must be carried out by qualifi ed personnel.

In order for the product system to work properly, the dynamic pressure of the water mains must be suitable for the specifi cations listed on the technical
sheet of the selected product. In the event pressure exceeds 350 kPa (3.5 bar) a suitable pressure reducer must be installed upstream of the mixer (or
product water supply point).
It is recommended to install mesh fi lters on the fl ow lines, in order to prevent problems caused by any impurities contained in the water and where they
are not already fi tted on the product.
The product must be connected to the water supply system, through a type CAa hydraulic disconnector, as defi ned by the European Standards on the
prevention of refl ux pollution, which does not interfere with normal installation of the product.
For proper installation it is necessary to have the following accessories which are not supplied by the manufacturer:
a) fi ttings required for the connection to the building's water mains (see Technical Notes of the product)
b) fi ttings required for the connection of the sunken drainage to the product drain siphon (if available in the model. See Technical Notes)
STEAM GENERATOR
(available only in some versions - Multifunctional showers).
Characteristics of the Steam Generator supply water, within which correct operation is ensured:
• pressure included between 150 and 350 kPa (1.5 and 3.5 bar)
• permitted hardness with a range from 10°F to 40°F (equal to 400 ppm as CaCO3)
• conductivity interval between 300 and 1250 μS/cm (normal waters)

The electrical power supply system must comply with the requirements of the International Installation Standards, as well as with the national legal
requirements.
PRODUCT POWER BOX (available only in some versions).
Before connecting the product, check that the system is capable to withstand the appliance power.
The manufacturer declines all liability for defects caused by instability of the electrical mains or of the electrical system upstream of the product (overvoltage
or overcurrent peaks). In the event of unstable electrical mains it is recommended to install a suitable stabilisation device, to protect the appliance in
the event of overvoltage or overcurrent peaks for the integrity of the product.
For the electrical connection to the power box (only for product versions that are equipped with a power box) use a type H07 RN-F cable of adequate
size according to the power absorbed by the product.
In the cable connecting to the power box, the earth terminal (Yellow Green) must be at least 30 mm longer than the phase and neutral conductors.
EARTH CABLE.
The earth cable must be connected in a fi xed and permanent manner to the electrical mains. The manufacturer declines all liability for defects or
malfunctions due to the absence or unsuitability of the earthing system.
EQUIPOTENTIAL CONNECTION.
The appliance must be connected to the equipotential system of the room and duly attached to the relevant terminal in the product.
The connection to the electrical mains requires the installation of a 30mA diff erential switch and of a class III overvoltage circuit breaker, with a contact
gap of at least 3 mm, with voltage and current suitably sized according to the product to be installed. The switches must be arranged near the appliance,
upstream of the power box (only for the product versions which are equipped with a power box).
This switch must be set to the "closed" position (ON) only for the time the product is used and then set back to the "open" position (OFF). It must not
be within the reach of persons using the product itself.
If the product is installed in a bathroom, the diff erential switch must be placed as defi ned by the International Installation Standards, as well as by the
national legal requirements and in any case far from potential water dispensing or spraying.
When the load-bearing structure of the product is made of metal, an effi cient earth system is required, featuring the sensitivity envisaged by the standards.
