WARNING

FIRE AND EXPLOSION HAZARD

Static electricity is created by the high velocity flow of fluid through the pump and hose. If your system is not properly grounded, sparking may occur and the system may become hazardous.

To reduce the risk of static sparking which can result in a fire or explosion and cause serious injury, follow these recommendations for providing electrical continuity throughout your system.

Also, read the WARNING section, FIRE AND EXPLOSION HAZARD on page 4.

1.Pump: Loosen the grounding lug locknut (A) and washer. Insert one end of a 12 ga (1.5 m2) minimum ground wire (B) into the slot in the lug (C). Tighten the locknut securely. See Fig. 3. Connect the other end of the ground wire to a true earth ground. Order a Grounding Clamp, P/N 103538, and a Grounding Wire, P/N 208950, (25 feet (7.6 m) long, 12 ga.).

2.Air and fluid hoses: Use only electrically conductive hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity.

3.Air compressor: follow the air compressor manufacturer’s recommendations

4.Spray gun or dispensing valve: Obtain grounding through connection to a properly grounded fluid hose and pump.

5.Fluid supply container: according to your local code.

6.Object being sprayed: according to local code.

7.All solvent pails used when flushing, according to local code. Use only metal pails which are conductive, placed on a positively grounded surface. Do not place the pail on a non-conductive 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 gun or dispensing valve firmly to the side of a grounded metal pail, then trigger the gun.
