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.
Fig. 1 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.
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: loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.5 mm2) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. See Fig 2. Con- nect the other end of the wire to a true earth ground. To order a ground wire and clamp, order Part No. 222011.

2.Air and fluid hoses: use only electrically conductive hoses.
3.Air compressor: follow manufacturer’s recommen- dations.
4.Spray gun: ground through connection to a proper- ly 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.
Mounting the Pump
Mount the pump to suit the type of installation planned. The pump dimensions and mounting hole layout are shown on page 24.
If the pump is immersed, be sure the pump intake is 1/2 in. (13 mm) off the bottom of the fluid container.
If the pump is mounted on the wall or on a stand, connect a suction line to the pump’s 3/4 in. npt(f) fluid inlet and place the other end of the line in the fluid container.
