6.Connect a grounded fluid hose (AH) to the 1/2 npt(f) fluid outlet (AL). In a circulating system, remove the pipe plug (2) and con- nect a fluid return line to the 3/8 npt(f) return port (AM).

Grounding

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.Pump: Connect Ground Wire (Y) to ground- ing screw (24) and tighten the screw securely. See FIG. 9. Connect the other

2.Air compressor: according to manufac- turer’s recommendations.

3.Fluid hoses: use only grounded hoses with a maximum of 300 ft (91 m) combined hose length to ensure grounding continuity.

4.Dispensing valve: grounding is obtained through connection to a properly grounded fluid hose and pump.

5.Object being sprayed: according to local code.

6.Fluid supply container: according to local code.

7.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.

8.To maintain grounding continuity when flushing or relieving pressure, always hold

a metal part of the spray gun/dispensing valve firmly to the side of a grounded metal pail, then trigger the gun/valve.
