PLUMBING CONNECTIONS

All water connection operations must be per-
formed after making sure that the spa's water
supply valve is CLOSED.
The connection must be made by an experi-
enced, 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 spa (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).
• Total alkalinity (TA) between 80 and 125 mg/l (8-12.5°f).
• pH between 7.4 and 7.8.
• 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 char-
acteristics of the water supply have been met (see "Pre-
Installation Sheet" on p. 13).

TAP WATER AND WELL WATER

To ensure maximum hygiene and durability of the spa 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 metals 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 softening 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.
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.

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
From 14ºf to 22ºf
From 22ºf to 32ºf
From 32ºf to 54ºf
........more than 54ºf
(1°f = 10 mg calcium carbonate per litre of water)

WATER ALKALINITY

Alkalinity (CAT) represents the concentration of bi-
carbonate ions present in the water. It is expressed as
mg/L of calcium carbonate or in French degrees (°f).
Ideal values of alkalinity range between 80 mg/L and
125 mg/L (8°f-12.5°f). Values outside of this range can
more easily cause variations of the pH. Instead, alkalinity
within the range noted makes it possible to "buffer" the
pH value, resulting in fewer abrupt variations.
WATER PH
What is pH?
The pH is a chemical parameter that gives an idea of
the acidity or basicity of the water. It can assume values
between 0 and 14. By definition water is considered
neutral if its pH is equal to 7. It is acidic if the pH is lower
than 7 and basic if the pH is greater than 7. Disinfectants
have an ideal pH at which they are most effective. In the
case of heated water treated with bromine products it is
recommended to keep the pH value in the range from
7.4 to 7.8 using chemical correctors as needed if the
pH is higher or lower to bring the the pH value back to
the recommended interval.
