Procedure
To spray HVLP, air pressure at the air cap must be
10 PSI (0.07 MPa, 0.7 bar) or less. To set up an
HVLP gun, do the following:
1.
Install an HVLP air cap.
See
Air Cap Selection Guide, page 96
2.
Follow steps 1–11 in the
3.
Fully open the fluid adjustment valve (H)
counterclockwise.
4.
Adjust the air in the air cap.
a.
Fully close the fan air adjustment valve (F)
clockwise, then open it counterclockwise two
turns.
b.
Fully close the atomizing air restrictor valve
(G) counterclockwise, then open it clockwise
one turn.
c.
Turn ON (I) the ES On-Off switch (J).
d.
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.

NOTE:
NOTE:
NOTE: The HVLP air cap requires a high
volume of air to atomize paint at low
pressure. Gun air regulator static pressure
settings of 70 PSI or higher are typically
required. To achieve the required gun air
pressures, use a shorter length air hose or a
larger diameter air hose. See Grounded Air
Hoses in
.
e.
Verify that the ES indicator (K) [Hz indicator
on Smart guns] is lit.

Description
Green
When spraying, the indicator
should remain green, indicating
sufficient air pressure to the
alternator turbine.
Amber
If the indicator changes to
amber after one second, the air
pressure is too low. Increase
air pressure until the indicator
is green.
Red
If the indicator changes to
red after one second, the air
pressure is too high. Decrease
air pressure until the indicator
is green. To maintain a higher
application air pressure, install
ES On/Off Valve Restrictor Kit
26A160. Adjust the pressure
as needed to ensure the
indicator remains green.
