Grounding
The following components must be grounded.
1. Pump
See F
IG. 4. Verify that the ground screw (GS) is
attached and tightened securely to the air motor.
Connect the other end of the ground wire (S) to a
true earth ground.
2. Pump fluid hoses
Use only electrically conductive fluid hoses. Check
electrical resistance of hoses. If total resistance to
ground exceeds 25 megohms, replace hose
immediately.
3. Air compressor
Follow manufacturer's recommendations.
4. Spray gun
Ground through connection to a properly grounded
fluid hose and pump.
5. Fluid supply container
Follow your local code.
6. Object being sprayed
Follow your local code.
7. Solvent pails used when flushing
Use only metal pails, which are conductive, placed
on a grounded surface. Do not place the pail on a
non-conductive surface, such as paper or
cardboard, which interrupts the grounding
continuity. All solvent pails used when flushing must
be grounded according to local code.
NOTE: 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.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding wire provides an escape
path for static electric current.
