HVLP Gun Gun Setup Setup Procedure
HVLP HVLP Gun Setup
To spray high pressure low volume (HVLP) spray
guns, 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
2. Follow steps 1–11 in the
Gun Setup Procedure, page
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
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 Hoses, page
e. Verify that the ES indicator (K) is lit. On
Smart guns, this is the Hz indicator.
