1.Pump: Use a ground wire and clamp as shown in Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.5 mm@) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order part number 237569 Grounding Clamp and Wire.
2.Air and fluid hoses: Use only electrically conduc- tive hoses.
3.Air compressor: Follow manufacturer’s recommen- dations.
4.Spray gun or dispensing valve: Ground through connection to a properly grounded fluid hose and pump.
5.Object being sprayed: Follow your local code.
6.Fluid supply container: Follow your local code.
7.Solvent pails used when flushing: Follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continu- ity.
8.To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.
