Installation
General Information
NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawing.
NOTE: Always use Genuine Graco Parts and Acces- sories, available from your Graco distributor. If you supply your own accessories, be sure they are ade- quately sized and pressure rated for your system.
Prepare the Operator
All persons who operate the equipment must be trained in the safe, efficient operation of all system components as well as the proper handling of all fluids. All operators must thoroughly read all instruction manuals, tags, and labels before operating the equip- ment.
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. 238909 Ground Wire and Clamp.

2.Pump air supply and fluid hoses: Use only electri- cally conductive hoses with a maximum of 500 feet (150 m) combined hose length to ensure ground- ing continuity. Check the electrical resistance of your air and fluid hoses at least once a week. If the total resistance to ground exceeds 29 megohms, replace the hose immediately.
NOTE: Use a meter that is capable of measuring resistance at this level.
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.
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
Ensure that you have an adequate compressed air supply. Bring a compressed air supply line from the air compressor to the pump location.
Be sure all air hoses (H and D) and fluid hose (N) are properly sized and
The air hose (H) should have a 3/8 npt (m) thread. A quick disconnect coupling is recommended.
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 25.
