Installation
Accessories are available from Graco. Be sure all
accessories are properly sized to withstand the pres-
sures in the system.
Mount Valve
Mount the valve on a 0.50 in. (12.7 mm) diameter rod on
a mounting fixture or a dispensing machine. The paint
gun has a clamping set screw (6) for mounting.
Connect the Air Lines
Clean all lines and connections of dirt, burrs, etc. and
blow them out with clean air before connecting them to
the system. Install an air filter in the air supply line to
remove harmful dirt and moisture from the compressed
air.
Connect Fluid Lines
Connect a grounded fluid line from the pump to the fluid
adapter of the paint spray gun. You should install a fluid
pressure regulator to control fluid pressure to the paint
spray gun. The regulator enables you to control fluid
pressure more accurately than by regulating hydraulic
pressure to the pump.
Install a fluid filter to remove particles and sediment
which may clog the tip.
Install a manual ball valve to shut off fluid flow to spray
gun.
Grounding
Proper grounding is essential to maintaining a safe sys-
tem.
To reduce the risk of static sparking, ground the pump,
paint spray gun, and all other system equipment.
1. Pump: Use a ground wire and clamp.
2. Air compressors and hydraulic power supplies:
Follow manufacturer’s recommendations.
3. Air and fluid hoses connected to the pump: Use
only grounded hoses with a maximum of 500 feet
(150 m) combined hose length to ensure grounding
continuity.
4. Dispensing valve: Obtain grounding through con-
nection to a properly grounded fluid hose and pump.
5. Fluid supply container: According to local code.
6. All solvent pails used when flushing: Ground
according to local code. Use only metal pails, which
are conductive. Do not place the pail on a non con-
ductive surface, such as paper or cardboard, which
interrupts the grounding continuity.
