1.
See Fig. 10. Use the Graco Grounded Air Supply
Hose (AH) to supply air to the gun. The gun air
inlet fitting has a left-hand thread. The air supply
hose ground wire (AG) must be connected to a
true earth ground. Do not connect the air supply
hose to the gun air inlet yet.
2.
Install an air line filter/water separator (AF) on the
gun 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 bleed-type air regulators (PR, GR) on
the pump and gun air supply lines to control air
pressure to the pump and gun.
Trapped air can cause the pump to cycle
unexpectedly, which can result in serious
injury, including splashing fluid in the eyes or
on the skin. Do not operate the equipment
without the bleed-type air valve (BV) installed.
4.
Install a bleed-type air valve (BV) on the pump
air supply line. The bleed-type air valve (BV) is
required in your system to shut off air to the pump
and relieve air trapped between the valve and
the pump after the air regulator is shut off. Install
an additional bleed-type air valve on the main air
line (MA) to isolate the accessories for servicing.
5.
Install an air bleed valve (BV) on each gun air
supply line to shut off air to the gun(s) and relieve
air trapped between the valve and the gun after
the air regulator is shut off.

1.
Blow out the fluid line (FL) with air and flush it
with solvent. Use solvent which is compatible
with the fluid to be sprayed. Do not connect the
fluid supply line to the gun fluid inlet yet.
2.
Install a fluid regulator (FR) on the fluid line to
control fluid pressure to the gun.
3.
Install a fluid filter (FF) near the pump outlet, to
remove particles and sediment which could clog
the spray nozzle.
To reduce the risk of serious injury, including
splashing fluid in the eyes or on the skin, do
not operate equipment without the fluid drain
valve (FD) installed.
4.
The fluid drain valve (FD) 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.
