41OPERATING MANUALEDITION 05/2015 ORDER NUMBER DOC23191507.3.2 CHECKING THE SPRAY PATTERN (WITHOUT ELECTROSTATICS)1. Switch off control unit. (The grounding of the spray gun via the gun cable is maintained.)2. Start up with product supply set to approx. 8 MPa; 80 bar; 1160 psi operatingpressure. See corresponding operating manual.Flat-jet method:AirLess spraying (without electrostatics)3. Turn air pressure regulator (6) all the way down.4. Spray (release locking device and pull trigger) and at the same time, check theatomization.5. Set the product pressure on the product supply to the point where a good productatomization is achieved.For round and flat-jet method:AirCoat spraying (without electrostatics)6. Adjust the air pressure regulator (6) until optimal atomization is achieved.see below, "Adjusting the spray pattern with the air pressure regulator"7. With the air adjustment on the gun, set the ratio of shaping air/atomizing air so as toachieve an optimum spray pattern.See below, "Spray pattern and air regulation"Repeat points 6 and 7 until the optimum spray pattern is reached (iterative process).1. Place empty tank (18) under return tube (8).2. Place suction hose (7) in the tank with working material (19).Note: If the pump is equipped with a rigid suction system, it should only be dippedin into the working material up to the middle of the inlet housing at the maximum!3. Adjust the pump-pressure regulator (12) to approx. 0.05 MPa; 0.5 bar; 7.25 psi.4. Open return valve (17).5. Slowly open the ball valve (11).6. Adjust the air pressure on the pump-pressure regulator (12) so that the pump runssmoothly.7. Close ball valve (11) as soon as pure working material starts coming from the returntube (8).8. Close return valve (17).9. Point the gun, without nozzle, into tank (18) and open it.10. Slowly open the ball valve (11).11. Close ball valve (11) as soon as pure working material starts coming from the gun.12. When there is no pressure remaining in the system, close the gun.13. Secure the gun.14. Dispose of the contents of the tank (18) according to the local regulations.7.3.1 FILLING WITH WORKING MATERIAL
