LVLP Compliance Kit Installation and Use
CAUTION:
If your location is subject to VOC emission regulations, make sure your
spray gun atomizing pressure is 0.69 bar (10 psi) or less by testing with a compliance air
cap. Refer to the chart on the following page for maximum air inlet settings to achieve
the 10 psi or less LVLP rating.
NOTE:
The gauge kit and the compliance air caps are sold separately. Order one gauge
kit, and compliance air caps of the same size as the production caps you normally use.
1.
Shut off the fluid delivery system and relieve fluid pressure. This is not required, but it
will prevent fluid from spraying while performing the compliance test.
2. Remove the retainer and production air cap from the gun. Install the compliance air
cap on the gun and tighten the retainer securely. (The compliance air cap comes with
its own retainer.)
3. Connect the gauges to the air cap.
4. Turn the gun atomizing air regulator all the way to MAX.
5.
Pull the trigger all the way back to allow full flow of air.
6. Check the air pressure gauges. Both atomizing and horn pressures must be 0.69 bar
(10 psi) or less. If either is higher, reduce the pressure.
7.
Reinstall the production air cap and paint cup and check the fluid atomization. You
can check the atomization with the compliance air cap installed, just make sure the
gauge tubing does not impinge the spray or kink.
