What does the standard provide?

Mandatory annual checks:

Appearance

pH

Total hardness

Electrical

conductivity

Chemical

conditioning

Frost protection

Checks for specific problems (e.g. corrosion)

or for further investigation:

Iron

Copper

Aluminium

Chlorides

Microbiological

parameters

Sampling points: A – Supply water upstream of any water treatment

r – Filling and/or top-up water upstream of any water treatment

Indicate the control methods for proper management of the water treatment systems

Notes

In the case of solar thermal

systems, the heat transfer fluid

could have both antifreeze and

chemical conditioning function.

Check to be carried out only if you

have antifreeze protection.

The control should only be carried out

where the chlorine content is suspected

to be incompatible with the characteristics

of the components of the plant.

The water in the system should be

strictly checked on an annual basis only

if a softener is installed in the top-up

circuit.

In the case of domestic hot water,

frequency and sampling points must

be identified on the basis of a risk

assessment carried out by qualified

personnel according to the indications in

the official documents (e.g. Guidelines

for inspection and prevention of the

infection with Legionella), as applicable.

n.B. For all types of systems, it is mandatory to create and keep up-to-date a record of the results of the checks carried

out, to be inserted and stored in the system booklet according to DPr 74/2013.
