1.1
Frost precautions
When there is danger of frost, and particularly in areas with very low temperatures, precautions
will need to be taken to prevent damage to the installation. It is recommendable to add anti-
freeze to the water in the primary circuit of the tank. The anti-freeze used must be compatible
with public health regulations and it must not be toxic
. DOMUSA TEKNIK
recommends the use
of propylene glycol, consulting the product manufacturer before use.
If the installation is to be out of use for a long period,
drain all the water from the tank
.
1.2
Water characteristics
The water must comply with the characteristics defined in the Technical Building Code, and
must be treated if necessary.
The water must be in accordance with Directive 98/83 / EC on the quality of water intended for
human consumption. Special attention must be paid to the following parameters:
- Maximum chloride concentration: 250 mg / l.
- Maximum sulphate concentration: 250 mg / l.
- Maximum concentration of chlorides and sulphates: 300 mg / l.
- Maximum conductivity: 800 µS / l.
When the chlorine concentration in the Domestic Water exceeds 250 mg / l., it is recommended
that anti-corrosion protection should be applied to the inside of the inter-accumulator so as to
avoid its premature deterioration. As an option
DOMUSA TEKNIK
supplies electronic cathodic
protection that is suitable for the Sanit inter-accumulator range. To install it, read carefully the
assembly instructions that are provided with the same.
