4.2 Connecting the Mixer to the hydraulic system
Maximum pressure at nozzle inlet line and Mixer service unit is 8 bars.
IMPORTANT!
Do not apply pressures above 8 bars to the mixer (see tables 2a ÷ 2c).
Connect the pump using the fittings supplied with the Mixer. Different fittings should be ordered separately.
The chemical is taken from Mixer tank via vacuum as produced by the Venturi pump under the very device.
The mixer outlet, draining in the tank, must be connected to the Ø 40 mm fitting (original equipment) or Ø 50 mm fitting (upon
request) through pipes tightened with suitable clamps.
Outlet pressure at hose tail Ø 40 mm, towards tank loading, are as follows:
- 0,2 bars with nozzle inlet pressure of 2 bars;
- 0,3 bars with nozzle inlet pressure of 3 bars;
- 0,4 bars with nozzle inlet pressure of 4 to 8 bars.

Install the Mixer in a user friendly position which is practical enough when the chemical product
is added.
Pay special attention to the following:
1) The cover should open without any problems and should not be in contact with any machine
parts;
2) The controls of the valves next to the Mixer and the main valve under the Mixer should not
be covered by any machine parts;
3) The Mixer should be at a practical height for the operator.
