Grounding
To reduce the risk of static sparking, ground the pump and all
your local electrical code for detailed grounding instructions
other components used or located in the spray area. CHECK
for your area and type of equipment and be sure to ground all
of these components:
1.
Pump: use ground wire and clamp as shown in Fig 1.
2.
Air and
fluid hoses: use only grounded hoses with a
of
500
feet
(150

to
en-
sure grounding continuity. Refer to Hose
Continuity.
3.
Air compressor: follow air compressor manufacturer's
recommendations.
4.
Spray gun or dispensing valve: obtain grounding through
connection to a properly grounded fluid hose and pump.
5. Object being sprayed: according to local code.
6.
Fluid
supply container: according to local code.
