Grounding

WARNING

FIRE AND EXPLOSION HAZARD Before operating the pump, ground the system as explained below. Also read the section FIRE AND EXPLOSION HAZARD on page 5.

3.Air compressor: follow manufacturer’s recommen- dations.

4.Spray gun: ground through connection to a prop- erly grounded fluid hose and pump.

5.Fluid supply container: follow your local code.

6.Object being sprayed: 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 firmly to the side of a grounded metal pail, then trigger the gun.

1.Pump: use a ground wire and clamp. See Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 1.5 mm@ (12 ga) 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 No. 237569 Ground Wire and Clamp.

System Accessories

Fig. 2 is only a guide for selecting and installing sys- tem components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

Air and Fluid Hoses

Be sure all air hoses (H) and fluid hoses (N and P) are properly sized and pressure-rated for your system. Use only electrically conductive hoses. Fluid hoses must have spring guards on both ends. Use a whip hose (P) and a swivel (R) between the main fluid hose (N) and the gun (S) to allow freer gun movement.

Mounting Accessories

Mount the pump (A) to suit the type of installation planned. Fig. 2 illustrates a wall mount system. Pump dimensions and the mounting hole layout are shown on page 27.

If you are using a floor stand, refer to its separate manual for installation and operation instructions.
