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 pres‐
sure level in the intake manifold.
The pressure switch allows a warning to be sig‐
nalled when the pressure falls below 0,5 bar.
B
Pressure switch (0,2 bar): this detects the pres‐
sure level in the intake manifold.
The pressure switch allows an "error" to be sig‐
nalled when the pressure falls below 0,2 bar
and stops machine operation.
C
Bypass valve: this is used to keep the fluid pres‐
sure in the drive circuit outlet pipe within the
maximum limit allowed.
D
Temperature sensor: this detects the coolant
temperature in the drive circuit outlet pipe.
Depending on the temperature detected, the
system will signal either a "Warning"(tempera‐
ture too high) or an "Error" (temperature contin‐
ues to rise, resulting in machine shutdown).
E
Pressure sensor: this detects, in real time, the
differential pressure between the intake pipe
and the drive circuit output pipe.
Through the sensor, the drive circuit outlet pipe
pressure is kept constant.
F
Check valve: this is used to stop the filling pump
intake pipe draining.

Processing and protection devices
Environmental conditions for operation
The machine works correctly with an ambient temperature of between 5 and
55 °C and a maximum humidity level of 95% (without condensation).
The machine is able to function properly at altitudes up to 2000 m above sea
level.
Permitted use
The machine is designed and manufactured to cool electric or electronic
equipment or machines.
Any other use than that specified, or not included or inferable from this man‐
ual, should be considered mishandling and therefore not permitted.
Improper and unauthorised uses
It is forbidden to use coolants with characteristics different from those speci‐
fied by the manufacturer.
