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.)

6.3.3 Water hardness
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.
