6.3.2 Environmental conditions for operation
The device cannot operate in
rooms classified as environ-
ments with an explosive atmos-
PROHIBITION
phere or at risk of fire.
The general operation of the de-
vice is guaranteed by observing
the environmental conditions in-
ATTENTION
dicated.
The device was not designed to
be installed outdoors, but to be
used in a "closed" environment
ATTENTION
not exposed to bad weather with
an ambient temperature between
+4 °C / +43 °C.
For the correct operation of the device it is necessary that its
positioning meets the following requirements:
• away from heat sources,
• away from direct sunlight,
• away from air conditioning systems,
• in a dust-free environment.
The environmental conditions for operation are shown in the
table below.
Ambient external air temperature (min. / max.)
-5 °C / +43 °C
6.3.3 Physical characteristics of water
The Langelier index of the water, measured at the operating
temperature, must be between 0 and +0.4.
The device must not operate with water hardness of less than
12°F. Conversely, if the water hardness is very high (over
25°F), use a suitably calibrated and monitored water softener,
because the residual hardness must not drop below 15°F.

The room must also be:
• Equipped with adequate water and electricity supply lines;
• Prearranged for the condensation water discharge connec-
tion;
• Prearranged with adequate water drains in case of boil-
er damage or safety valve intervention or the breakage of
pipes/connections;
• Equipped with possible containment systems in case of se-

complied with.
The equipment must be in-
stalled and operated by a qual-
ified technician
ance with local
