Grounding
To reduce the risk of static sparking, ground the pump
and all other components used or located in the
spray/dispensing area. Check your local electrical code
for detailed instructions for your area and type of equip-
ment and be sure to ground all of these components.
• Pump: Ground the pump by connecting a grounding
wire (12 ga minimum) from the pump's grounding
lug to a true earth ground.

• Air compressor and hydraulic power supply: Ground
according to local code and manufacturer's recom-
mendations.
• Fluid hoses: Use only grounded hoses with a maxi-
mum of 500 feet (150 m) combined hose length to
ensure grounding continuity.
• Dispensing valve: Obtain grounding through con-
nection to a properly grounded fluid hose and pump.
• Fluid supply container: According to local code.
• Object being sprayed: According to local code.
• All solvent pails used when flushing, according to
local code. Only use metal pails which are conduc-
tive. Do not place the pail on a non-conductive sur-
face, such as paper or cardboard, which interrupts
the grounding continuity.
• To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
gun firmly to the side of a grounded metal waste
container, then trigger the gun.
