Double-Acting Gun
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 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.
