Grounding
General Grounding Guidelines
Pump: use ground wire and clamp (supplied). Connect
ground clamp to a true earth ground.
Air and fluid hoses: use only electrically conductive
hoses.
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
FRP Proportioner Grounding
NOTE: All proportioners come with one grounding
clamp to ground the proportioner to a true earth ground.
All accessories for internal mix systems come with a
second grounding clamp to ground the solvent flush
system to the cart.
1. Verify that the ground screw is attached and tight-
ened securely to the air motor. Connect the other
end of the ground wire to a true earth ground.
2. For internal mix systems only, ground the solvent
flush system.
a. For solvent flush diaphragm pumps only, con-
nect one end of the second grounding clamp to
the solvent pump grounding strip. See the dia-
phragm pump manual listed on page 3 for
grounding details.
b. Connect the other end of the grounding clamp
to the cart.
3. Use an ohmmeter to verify all components are
grounded to the earth ground.
4. If wall power is used to power the heater, ground
electrical connection according to local codes.
5. For cart proportioners: Connect the other end of the
second supplied grounding clamp to the cart.
For wall proportioners: Connect the other end of the
second supplied grounding clamp to a true earth
ground.
The equipment must be grounded to reduce the risk of
static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
