Grounding
To reduce the risk of static sparking, ground the pump,
object being sprayed, and all other spray/dispensing
equipment used or located in the spray/dispensing
area. Check you local electrical code for detailed
grounding instructions for your area and type of equip-
ment. Be sure to ground all of this spray/dispensing
equipment:
1. Pump: loosen the grounding lug locknut (W) and
washer (X). Insert one end of a 1.5 mm
2 (12 ga)
minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely. See Fig. 1.
Connect the other end of the wire to a true earth
ground. Order Part No. 237–569, Ground Wire and
Clamp.
2. Air compressor: follow manufacturer’s recommen-
dations.
3. Air and fluid hoses: use only grounded hoses with
a maximum of 500 ft (150 m) combined hose
length to ensure grounding continuity.
4. Spray gun: grounding is obtained through connec-
tion to a properly grounded fluid hose and pump.
5. Object being sprayed: according to your local
code.
6. Fluid supply container: according to your local
code.
7. All solvent pails used when flushing, according to
local code. Use only metal pails, which are con-
ductive, placed on a grounded surface. Do not
place the pail on a nonconductive surface, such as
paper or cardboard, which interrupts the grounding
continuity.
8. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun firmly to the side of a grounded metal
pail, then trigger the spray gun.
