(due to the presence of potentially explosive
atmospheres - ATEX or with required IP level
higher than that of the unit) or in applications
requiring safety features (fault-tolerant, fail-safe)
which may be systems and/or technologies to
support life or any other context in which the
malfunction of an application can lead to death
or injury to people or animals, or serious dam-

5.4.2 Water hardness

The unit must not operate with water of hardness under 12°F;
however, with particularly hard water (above 25°F), it is advis-
able to use a properly calibrated and monitored water softener,
in this case the residual hardness must not fall below 15°F.
NB!: In the design and construction phase of the plants,
the applicable local regulations and provisions must be
respected.
