PLUMBING CONNECTIONS
All water connection operations must be
performed after making sure that the bathtub's
water supply valve is CLOSED.
The connection must be made by an
experienced, qualified plumber.
It is recommended to use ONLY tap water. If this
is not possible refer to the "more information"
section to the side.
The plumbing connection must be:
• Dedicated exclusively to the bathtub (it is not possible
to connect other equipment to the same connection).
• Made with hoses and connectors that are new and
never used.
CHARACTERISTICS OF THE WATER SUPPLY
The optimal values for the water supply are as follows:
• Hardness between 7ºf and 14ºF (fresh water) - 200 to
400 mg/l (ppm).
• minimum inlet pressure: 150,000 Pa (1.5 bar)
• minimum inlet pressure: 300,000 Pa (3 bar)
• Water suitable for human consumption.
Make sure that during the pre-installation all the
characteristics of the water supply have been met (see
"Pre-Installation Sheet" on p. 9).

WATER HARDNESS
Water hardness (TH) is determined by the total content
of calcium and magnesium present in the water, coming
from their soluble salts.
Water classification:
........up to 7ºf
=
Very soft water
From 7ºf to 14ºf
=
Soft water
From 14ºf to 22ºf
=
Slightly hard water
From 22ºf to 32ºf
=
Fairly hard water
From 32ºf to 54ºf
=
Hard water
........more than 54ºf
=
Very hard water
(1°f = 10 mg calcium carbonate per litre of water)

TAP WATER AND WELL WATER
To ensure maximum hygiene and durability of the bath-
tub it is essential to pay close attention to the quality of
the water that will be used to fill it. It is important that
the water used be drinkable. It is always advisable not to
use well water because it may be very hard, rich in met-
als like iron and manganese, and have bacterial loads.
Tap water is recommended. In the case of very hard or
ferrous water it is always recommended to install soften-
ing and iron removal systems upstream. The company
cannot be held responsible for issues related to the use
of non-drinkable water or lack of installation of such
systems.
The plumber is responsible for choosing the
type of components to be used and the verification of
compliance with the purity and potability parameters
of the water supply.
