Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE OR EXPLOSION
HAZARD on page 3.
1.
Pump: use a ground wire and clamp as shown in
your separate pump manual.
2.
Fluid hoses: use only grounded fluid hoses with a
maximum of 500 feet (150 m) combined hose
length to ensure grounding continuity. Check the
electrical resistance of your fluid hoses at least
once a week. If your hose does not have a tag on
it which specifies the maximum electrical resist-
ance, contact the hose supplier or manufacturer
for the maximum resistance limits. If the hose
resistance exceeds the recommended limits,
replace it immediately.
3.
Air compressors and hydraulic power supplies:
ground the equipment according to the manufac-
turer’s recommendations.
4.
Flo-valve: ground through connection to a properly
grounded fluid hose and pump.
5.
Fluid supply container: Ground according to your
local code.
6.
Flammable liquids in the spray area: must be kept
in approved, grounded containers. Do not store
more than the quantity needed for one shift.
7.
Solvent pails used when flushing: follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continu-
ity.
8.
To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded
metal pail,
then trigger the gun.
