NOTE
These hoses must be held on the respective noz-
zles using hose clips to avoid that the tube(s) gets
loose or disconnected during operation.
Cooling may be carried out either through an open
circuit with eventual discharge of the water, or us-
ing a closed circuit cooling system.
The water temperature must be between +10°C
and +20°C, with an inlet pressure between 3 and 5
bar. This allows a flow of about 200 l/h.
NOTE
The water electrical conductance must be
µ
s/cm. When the conductance is higher, in closed
water circuit, the use of up to 20% of Ethyl-Glycole
is suggested.

VENT ACCESSORIES

The vent valve and vent device allow to avoid un-
desired venting of the pump during temporary
power failure and enables an automatic vent op-
eration.

Then screw the vent valve into the pump and
tighten it using a 16 mm hexagonal spanner with a
torque of 2.5 Nm.
Do not overtighten the valve as this may damage
the thread on the pump.

able connector on the controller (see the preced-
ing paragraph "INTERCONNECTIONS").
