Processing and protection devices
Serious health and safety risks!
WARNING
Do not tamper with, circumvent, remove or bypass processing and protection
devices; failure to comply with this requirement may cause serious health and
safety risks.
A
Pressure switch (0,5 bar): this detects the
pressure level in the intake manifold.
The pressure switch allows a "Warning"
to be signalled when the pressure falls
below 0,5 bar.
B
Pressure switch (0,2 bar): this detects the
pressure level in the intake manifold.
The pressure switch allows an "Error" to
be signalled when the pressure falls be‐
low 0,2 bar and stops machine operation.
C
Bypass valve: this is used to keep the flu‐
id pressure in the outlet pipe within the
maximum limit allowed.
D
Temperature sensor: this detects the
coolant temperature in the outlet pipe.
Depending on the temperature detected,
the system will signal either a "Warn‐
ing"(temperature too high) or an "Error"
(temperature continues to rise, resulting
in machine shutdown).
E
Pressure sensor: this detects, in real
time, the differential pressure between
the intake pipe and the output pipe.
Through the sensor, the outlet pipe pres‐
sure is kept constant.
F
Check valve: this is used to stop the filling
pump intake pipe draining.

level.
Permitted use
The machine is designed and manufactured to cool electric or electronic
equipment or machines.
The machine must be used in conformity with its technical characteristics; it is
forbidden to make modifications or use the machine for improper uses.
The machine can be used either indoors or outdoors, in areas exposed to the
weather.
