INSTALLATION
Mount the Gun
Mount the gun on a stationary support or on a reciprocat-
ing arm. The mounting rod must be
properly grounded.
Mount the gun so the front of the gun is 254 to 300 mm (10
to 12 in.) from the work piece.
Connect the Air Line
(Refer to the Typical
Installation Drawing)
WARNING
To reduce the risk of electric shock or other serious
bodily injury, the air supply hose must be electrically
connected to a true earth ground. Use Only Graco
Electrically Conductive Air Supply Hose. This
hose, and the gun, have special threads which pre-
vent using any other type of hose with the gun. See
the ACCESSORIES section to order the hose.
1.
Install an air line filter (K) and an air and water sepa-
rator (B) on the main air line to ensure a dry, clean air
supply to the gun. Dirt and moisture can ruin the ap-
pearance of your finished workpiece and can cause
the gun to malfunction.
2.
Install an air line lubricator (D) close to the pump air
inlet.
3.
Install a normally closed, 3-way air solenoid (P) or
manual valve on the turbine, cylinder and remote fan
air supply lines.
(The remote fan line is optional.)
4.
Install a bleed-type air regulator (E) on the pump,
turbine, atomizing, cylinder, and remote fan
(option-
al) air supply lines to control air pressure to the pump
and gun.
5.
Install a bleed-type air shutoff valve (A) on the main
air line, the pump line, and each gun air supply line to
shut off air to the pump and gun.
WARNING
The
bleed–type air shutoff valve (A) 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 bodily
injury, including splashing in the eyes or on the skin
and injury from moving parts.
6.
Connect the cylinder air line to the gun’s cylinder air
inlet (marked CYL).
7.
Connect the atomizing air line to the gun’s atomizing
air inlet (marked ATOM).
8.
Connect the turbine air supply line to the gun’s air in-
let (marked ES).
The gun air inlet fitting has a left
hand thread. Connect the air supply hose ground
wire to a true earth ground.
9.
A remote fan air adapter is available to control the fan
air at the control booth. See Installing the Optional
Remote Fan Air Adapter, on page 8.
Connect the Fluid Line
(Refer to the Typical
Installation Drawing)
1.
Before connecting the fluid line, blow it out with air
and flush it with solvent. Use solvent which is com-
patible with the fluid to be sprayed.
2.
Install a fluid regulator (L) on the fluid line to control
fluid pressure to the gun.
3.
Install a fluid filter (G) and drain valve (H) at the pump
outlet.
WARNING
The
fluid drain valve (H) is required in your system
to assist in relieving fluid pressure in the displace-
ment pump, hose and gun; triggering the gun to
relieve pressure may not be sufficient. Install a
drain valve close to pump’s fluid outlet. The drain
valve reduces the risk of property damage or seri-
ous bodily injury, including splashing in the eyes or
on skin and contamination from hazardous fluids.
4.
Connect the fluid line to the gun fluid inlet.
CAUTION
Do not use metal fittings at the gun barrel. For cir-
culation systems, use plastic fittings.
