Gun Setup
13. Fully open the fan air adjustment valve (F)
counterclockwise.
14. Fully open the uid adjustment valve (H)
counterclockwise.
15. Fully open the atomizing air restrictor valve (G)
clockwise.
16. Turn ON (I) the ES On-Off switch (J).
17. Set the gun air regulator to deliver a minimum
45 psi (0.32 MPa, 3.2 bar) at the gun when
triggered, to ensure full spraying voltage. See
the table below.

Green
When spraying, the indicator
should remain green, indicating
sufcient air pressure to the
alternator turbine.
Amber
If the indicator changes to amber
after 1 second, the air pressure
is too low. Increase air pressure
until the indicator is green.
Red
If the indicator changes to red
after 1 second, the air pressure is
