Technical Information
Two 6 mm (1/4") internal diameter rubber or plastic hoses from the water supply
must be fitted to the two nozzles.
These hoses must be held on the respective nozzles using clamps to avoid the
NOTE
tubes from becoming loose or disconnected during operation.
Cooling may be carried out either through an open circuit with eventual discharge of
the water, or using a closed circuit cooling system.
The water temperature must be between +15 °C and +30 °C with a flow rate higher
than 50 l/h (0.22 GPM). The max water inlet pressure must be lower than 5 bar.
The water electrical conductance must be ≤ 500 µs/cm. When the conductivity is
NOTE
higher, in closed water circuit, the use of up to 20 % of Ethyl-Glycole is
recommended.
