Installation
Fluid Line Accessories
Install the following accessories in the positions shown in Fig. 2, using adapters as necessary:
DA fluid drain valve (N) is required in your system to relieve fluid pressure in the hose and gun (see the WARNING at left). Screw the drain valve into the open branch of a tee mounted in the fluid line. Install the drain valve pointing down, but so the handle points up when opened.
DA fluid regulator (P) controls fluid pressure to the gun/valve, and dampens pressure surges.
DA gun or valve (S) dispenses the fluid. The gun shown in the Typical Installation is a dispensing gun for highly viscous fluids.
DA gun swivel (T) allows freer gun movement.
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 4.
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.

2.Air and fluid hoses: use only electrically conductive hoses.
3.Air compressor: follow manufacturer’s recommen- dations.
4.Spray gun/dispense valve: ground through connec- tion to a properly grounded fluid hose and pump.
5.Fluid supply container: follow your local code.
6.Object being sprayed: follow your local code.
7.All solvent pails used when flushing: follow your 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 gun/valve firmly to the side of a grounded metal pail, then trigger the gun/valve.
