It is recommended to use OnlY tap water.
If this is not possible refer to the “more informa-
tion” section to the side.

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.

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)
WATEr AlkAlInITy
Alkalinity (CAT) represents the concentration of bicar-
bonate 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, alkalin-
ity 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. Disinfect-
ants 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 pH
value back to the recommended interval.

To ensure maximum hygiene and durability of the min-
ipool 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 in-
stall 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.
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.
