4.2
Degrees of protection provided by
enclosures
The degree of protection of the equipment is
equal to: IPX4.
4.3
Limitations of use
WARNING!: This device has not been
designed, nor is it intended for use
within hazardous environments (due to
the presence of potentially explosive
atmospheres –according to ATEX
standards or with a requested IP level
exceeding that of the equipment) or in
applications that require (fault-tolerant,
fail-safe) safety characteristics such as
in circuit-breaking systems and/or
technologies or in any other context in
which the malfunctioning of an
application could cause death or
injury to people or animals or serious
damage could be caused to objects
or the environment.
N.B.: In the event of a product
breakdown or fault, this could cause
damage (to people, animals and
goods). It is necessary to arrange for a
separate functional monitoring system
with alarm functions in order to avoid
such damage being caused.
Moreover, it is necessary to arrange for
a back-up service in case of failure!
4.4
Operating limits
The above mentioned device is intended to be
used exclusively for the heating of domestic hot
water within the foreseen limitations of use
described below. For this sake it must be
connected with the domestic water supply
network (paragraph 5.5) and with the power
supply network (paragraph 5.6).
4.4.1 Temperature range
4.4.2 Water hardness
The equipment should not work with water
hardness lower than 12°F; on the contrary, when
the water hardness is particularly high (higher than
25°F), it is recommended to use a water softener,
properly calibrated and monitored; in this case
the residual hardness should not fall below 15°F.
N.B.: The manufacturer shall not be
held responsible under any
circumstances in the event that the
equipment is used for other purposes
than for which it has been designed
and as regards any installation errors
or equipment misuse.
WARNING! It is forbidden to use the
device for purposes other than those
intended. Any other use is to be
considered improper and therefore not
allowed.
N.B.: During the design and
construction stage of the systems,
current local rules and provisions are
complied with
