NOTE: HVLP and Compliant Gun Limits

HVLP Guns: local laws may limit the maximum pressure to 10 psi (70 kPa, 0.7 bar) at the air cap for compliance. See the table on page 7 for maximum HVLP/Compliant manifold inlet pressures. To measure pressure at the air cap, use the appropriate HVLP Pressure Verifica- tion Kit. See Accessories, page 34.

Compliant Guns: See the table on page 7 for maximum HVLP/Compliant manifold inlet pres- sures.

3.Test the spray pattern atomization while keeping the gun a consistent distance, about 6 to 8 inches (150 to 200 mm), from the test piece.

Check the atomization quality. Increase the gun atomizing air supply pressure with the air pressure regulator in 5 psi (34 kPa, 0.3 bar) increments until you obtain the desired atomization.

NOTE: For the best transfer efficiency, use the lowest setting needed to achieve desired finish quality.

Setup

4.If the spray pattern is too wide or split, reduce the fan air pressure (or slightly close the fan adjustment valve on manifold 288223).

To further control the spray pattern of air- spray guns only, use an alternate air cap. For a list of available air caps, refer to Accessories, page 34.

NOTE: Reducing the fan air pressure to 0 psi (or fully closing the fan adjustment valve) will produce a round pattern.
