Grounding
WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of fire, explosion, and
serious injury, proper electrical ground-
ing of every part of your system is es-
sential. Read the warning section Fire
and Explosion Hazard on page 4, and
follow the grounding instructions below.
The following grounding instructions are minimum
requirements for a basic dispensing system. Your
system may include other equipment or objects which
must be grounded. Check your local electrical code for
detailed grounding instructions for your area and type
of equipment. Your system must be connected to a
true-earth ground.
D
Pump: ground the pump by connecting ground wire
and clamp as described in your separate pump
instruction manual.
D
Air compressors and hydraulic power supplies:
ground the equipment according to the
manufacturer’s recommendations.
D
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 resistance,
contact the hose supplier or manufacturer for the
maximum electrical resistance limits, replace the
hose immediately.
D
Dispensing valve: ground the valve by connecting it
to a properly grounded fluid hose and pump.
D
Fluid supply container: ground according to your
local code.
D
Flammable liquids in the spray area: must be in
approved, grounded containers. Do not store more
than the quantity needed for one shift.
D
All solvent pails used when flushing: ground
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.
D
To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the valve
firmly to the side of a grounded metal pail, then
trigger the valve.
How to Use the Valve Trigger Safety
WARNING
To prevent accidental triggering of the
gun and reduce the risk of a serious inju-
ry, including fluid injection or splashing in
the eyes or on the skin, lock the gun trigger safety
when you stop dispensing.
SKIN INJECTION HAZARD
1.
If you are using one of the hand-held versions of
the valve, lock the valve trigger safety by turning
the latch to a right angle with the gun body. See
Fig. 2.
2.
To unlock the valve trigger safety, push the latch
out and turn it parallel with the gun body.
