To reduce the risk of static sparking, ground the pump and
all other equipment used or located in the pumping area.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Ground
all of this equipment.

2. Air compressor: according to manufacturer's
recommendations.
3. Fluid hoses: use only grounded hoses with a
maximum of 500 ft (150 m) combined hose length to
ensure grounding continuity. Refer to Hose
Grounding Continuity.
4. Dispensing valve: grounding is obtained 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.
7. All solvent pails used when flushing, according to
local code. Use only metal pails, which are
conductive. Do not place the pail on a non-conductive
surface, such as paper or cardboard, which interrupts
the grounding continuity.
8. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun/dispensing valve firmly to the side of a
grounded metal pail, then trigger the gun/valve.
