Pressure Relief Procedure

1.Turn off the air and fluid supply to the gun.

2.Close the bleed-type master air valve (required in the system).

3.Trigger the gun into a grounded metal waste con- tainer to relieve the fluid pressure.

4.Open the pump drain valve (required in the system) to relieve fluid pressure in the displacement pump. In addition, open the drain valve connected to the fluid pressure gauge (in a system with fluid regula- tion) to relieve fluid pressure in the hose and gun. Have a container ready to catch the drainage.

5.Leave the drain valve(s) open until you are ready to spray again.

6.If you suspect that the spray tip or hose is com- pletely clogged or that pressure has not been fully relieved, very slowly loosen the hose end coupling and relieve pressure gradually, then loosen the cou- pling completely. Clear the tip or hose obstruction.

Adjust Spray Pattern

The air-assisted spray gun combines airless and air spray concepts. The spray tip shapes the fluid into a fan pattern, as does a conventional airless spray tip. Air from the air cap further atomizes the fluid and completes the atomization of the paint tails into the pattern to pro- duce a more uniform pattern.

The fan air can be used if necessary to slightly adjust the pattern size.

Air-assisted spray guns differ from air spray guns in that increasing the fan air reduces the pattern width. To increase the pattern width, use less fan air or a larger size tip.

1.Set the fluid pressure at 300 psi (2.1 MPa, 21 bar) with the fluid regulator.

2.Trigger the gun to check the atomization; do not be concerned about the pattern shape yet.

3.Slowly Increase the fluid pressure just to the point where a further increase in fluid pressure does not significantly improve fluid atomization.

4.Turn on the atomizing air and set the air pressure at about 10 psi (70 kPa, 0.7 bar). Check the spray pat- tern, and then adjust the air pressure until the tails are completely atomized and pulled into the spray pattern. See FIG. 11. Do not exceed 100 psi (0.7 MPa, 7 bar) air pressure to the gun.

For HVLP operation do not exceed 10 psi at the air cap. Use HVLP verification kit 249140 to measure the atomization pressure at the air cap.
