Grounding the System
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.
1.
ETL—Listed Pumps: Use a ground wire, connector,
and clamp. See F
. 1. Loosen screw (X). Insert one
exposed end of a 12 ga (1.5 mm
2
) minimum ground
wire (Y) through the eye of the ground terminal
connector (W) and tighten screw (X) securely.
Connect the other end of the wire to a true earth
ground. Order Part No. 237569 Ground Wire and
Clamp.
2.
Non ETL-Listed Pumps: See F
ground screw (Z). Fasten the ground connector (W)
onto the pump with the ground screw (Z) and tighten
securely. Loosen screw (X). Insert one exposed end
of a 12 ga (1.5 mm
2
) minimum ground wire (Y)
through the eye of the ground terminal connector
(W) and tighten screw (X) securely. Connect the
other end of the wire to a true earth ground. Order
Part No. 222011 Ground Connector/Wire and
Clamp.
3.
Air and fluid hoses: use only electrically conductive
hoses.
4.
Air compressor: according to manufacturer’s
recommendations.
5.
Dispensing valve: grounding is obtained through
connection to a properly grounded fluid hose and
pump.
6.
Fluid supply container: according to local code.
7.
Object being sprayed: according to local code.
8.
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.
