Spraying
1. Apply a minimum of 50 psi (3.5 bar, 0.35 MPa) air
pressure to the cylinder air fitting (CYL) to activate
the on/off sequence of atomization air (A2) and fluid
(P1). See F
IG. 12..
2. Turn the gun functions off and on by using the air
solenoid valves on the cylinder (CYL) and turbine
(TA) air supply lines.
3. To change to a lower voltage setting, activate the
solenoids controlling the KV1 and KV2 ports. See
Changing the kV Setting on page 7.
Triggering the Fluid Alone
1. Shut off and relieve the air pressure to the atomiza-
tion (A2) air line, using the bleed-type air shutoff
valve.
2. Apply 50 psi (3.5 bar, 0.35 MPa) air pressure to the
cylinder air fitting (CYL) to trigger the fluid.
Shutdown
