Setup

System Requirements

Pressure drain valves are recommended in the system. 
Pressure drain valves assist in relieving fluid pressure in 
the displacement pump, hose and gun in the event that 
the gun is clogged and triggering the gun does not 
relieve all pressure.

Grounding

Check your local electrical code and pump or sprayer 
manual for detailed grounding instructions.

Spray gun:

 ground through connection to a properly 

grounded fluid hose and pump.

Pump:

 follow manufacturer’s recommendations.

Fluid hose:

 use only electrically conductive hoses with 

a maximum of 500 ft. (150 m) combined hose length to 
ensure grounding continuity. Check electrical resistance 
of hoses. If total resistance to ground exceeds 29 
megohms, replace hose immediately.

Fluid supply container:

 follow local code.

Object being sprayed: 

follow local code. 

Solvent pails used when flushing: 

follow local code. 

Use only conductive metal pails, placed on a grounded 
surface. Do not place the pail on a nonconductive 
surface, such as paper or cardboard, which interrupts 
grounding continuity.

To maintain grounding continuity when flushing or 
relieving pressure: 

hold metal part of the spray gun 

firmly to the side of a grounded metal pail, then trigger 
the gun.

The equipment must be grounded to reduce the risk 
of static sparking. Static sparking can cause fumes to 
ignite or explode. Grounding provides an escape wire 
for the electric current.
