Start air-spraying (without electrostatics)
1. Switch off control unit. (The pressure regulators continue to function.)
2. Set pump pressure regulator (9) depending upon the paint viscosity (see operating
manual of the product pressure generator).
– DD10 pump: approx. 0.2–0.6 MPa; 2–6 bar; 30–90 psi
– DD10-/ZIP52 pump with product pressure regulator: approx. 0.3–0.6 MPa; 3–6 bar;
40–90 psi
3. DD10-/ZIP52 pump with product pressure regulator:
Set product pressure regulator (10) to approx. 0.05–0.2 MPa; 0.5–2 bar; 7–30 psi
operating pressure.
4. Set atomizing air regulator (11) to approx. 0.2–0.4 MPa; 2–4 bar; 30–60 psi.
5. Open air regulator at the rear of the gun.
6. Set the union nut as far as the stop.
7. Spray (actuate trigger) and check the atomization.
8. – DD10 pump:
Use the pump pressure regulator (9) and atomizing air regulator (11) to set the
spray pressure to a point at which optimal product atomization is achieved.
– DD10-/ZIP52 pump with product pressure regulator:
Use the product pressure regulator (10) and atomizing air regulator (11) to set the
spray pressure to a point at which optimal product atomization is achieved.
9. Flat jet process: with the air adjustment on the gun, set the ratio of shaping air/
atomizing air so as to achieve an optimum spray pattern.
Changing the Flow Rate
Adapt product pressure.
Use a different fan spray nozzle (see Chapter 13).
Limit the valve needle stroke with the adjustment screw on the side of the gun.
