SPRAYING
1. Insert the desired nozzle into the spray gun.
2. Turn on the control unit. See corresponding operating manual.
3. Start up with product supply generator set to approx. 0.05 to 0.15 MPa; 0.5 to 1.5 bar;
7 to 22 psi operating pressure. See corresponding operating manual.
4. Set atomizing air regulator (4) to approx. 1–4 bar.

Pressing the trigger on the spray gun switches the high-voltage supply on.
7. Adjust the product pressure and atomizing air in accordance with the nozzle and
object.
Rule of thumb
: Set atomizing air pressure approx. three times higher than the
product pressure.
