Introduction
How the Electrostatic Air Spray Gun Works
The air hose supplies air to the spray gun. Part of the
air operates the turbine and the rest of the air atomizes
the fluid being sprayed. The turbine generates power,
which is converted by the power cartridge, to supply
high voltage current to the gun’s ionizing electrode.
Converting a PRO 3500sc Gun
to a PRO 3500hc Gun
NOTE: See page 38 to order Conversion Kit 223451.
1. Remove the air cap, nozzle/resistor stud, and
electrode as described in Electrode Replacement
(page 25).
2. Remove the fluid seal (A), fitting (B), tube (C), nut
(D), and ferrules (E) from the gun. See Fig. A.
The pump supplies fluid to the hose and gun, where
the fluid is electrostatically charged as it passes the
electrode. The charged fluid is attracted to the
grounded workpiece, wrapping around and evenly
coating all surfaces.
5. Replace the existing fluid packing cartridge (K)
with the new cartridge (28) supplied with Conversion Kit 223451. See Fig. D.
6. Install the threaded fitting, located on the tube
assembly (12), into the gun barrel. See Fig. D.
Turn the fitting until the o-ring (12b) is compressed.
7. Wrap the tube around the barrel. See Fig. D.
CAUTION
To ensure proper installation of the new parts, make
sure that the fluid seal (A) does not remain in the gun
barrel.
3. Using a soft brush and solvent, carefully clean
area inside of the barrel where the fluid seal (A)
used to be.
4. Remove the trigger (M).
8. Slide the shroud (10) up the fluid tube (12), as
shown in Fig. B.
9. Pull the shroud upward as you press it onto the
barrel, as shown in Fig. C. Be sure the hose is
completely inside the shroud before pressing the
shroud onto the barrel.

WARNING
ELECTRIC SHOCK HAZARD
To reduce the risk of electric shock or
other serious injury, the air supply hose
must be electrically connected to a true
earth ground. Use Only Graco Electrically Con-
ductive Air Supply Hose.
1. Connect the Graco Electrically Conductive Air
Supply Hose (R) between the air supply line and
the gun’s air inlet (V). The gun air inlet fitting has a
left hand thread. Connect the air supply hose
ground wire to a true earth ground.
2. Install an air line filter (O) and an air and water
separator (D) on the air line to ensure a dry, clean
air supply to the gun. Dirt and moisture can ruin
the appearance of your finished workpiece and can
cause the gun to malfunction.
3. Install a bleed-type air regulator (G) on the pump
and gun air supply lines to control air pressure to
the pump and gun.
4. Install a bleed-type air shutoff valve on the main air
line (C) and the pump air line (E) to shut off air to
the pump. Install an additional bleed-type valve on
each pump air supply line to relieve air trapped
between this valve and the pump after the air
regulator is shut off.
WARNING
FLAMMABLE OR TOXIC
VAPOR HAZARD
Provide fresh air ventilation to avoid the
buildup of flammable or toxic vapors. Do
not operate the gun unless ventilation
fans are operating.
Electrically interlock the gun air supply with the ventilators to prevent gun operation without ventilating fans
operating. Check and follow all National, State, and
Local codes regarding air exhaust velocity
requirements.
WARNING
PRESSURIZED EQUIPMENT HAZARD
The bleed-type air shutoff valve is required in your
system to relieve air trapped between this valve
and the pump after the air regulator is closed.
Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury, including
splashing in the eyes or on the skin.
5. Install an air line lubricator (F) as close to the
pump (H) as possible.
6. Install an air shutoff valve ( P) on each gun air
supply line to shut off air to the gun(s).
308018 9
Installation
Connect the Exhaust Tube
Press the exhaust tube (provided) onto the barbed
adapter on the bottom of the gun handle. Secure the
tube with the clamp provided. Refer to page 36.
Connect the Fluid Line (Refer to Fig. 1)

compatible with the fluid to be sprayed.
2. Install a fluid regulator (M) on the fluid line to
control fluid pressure to the gun.
3. Install a fluid filter (K) and drain valve (U) at the
pump outlet.
WARNING
PRESSURIZED EQUIPMENT HAZARD
The fluid drain valve (U) is required in your system
to assist in relieving fluid pressure in the displacement pump, hose and gun; triggering the gun to
relieve pressure may not be sufficient. Install a
drain valve close to the pump’s fluid outlet. The
drain valve reduces the risk of serious injury,
including splashing in the eyes or on the skin.
4. Connect the fluid line to the 3/8–18.6(m) gun fluid
inlet (W).
5. Before running any paint through the spray gun,
flush it out with a compatible solvent.
