Installation
General Information
• A typical installation is shown in FIG. 2. It is only a
guide for selecting and installing system
components. Contact your Graco distributor for
assistance in planning a system to suit your needs.
• Always use genuine Graco parts and accessories.
• Reference numbers and letters in parentheses refer
to the callouts in the figures.
Tighten Clamps Before First Use
After you unpack the pump, and before you use it for the
first time, check all clamps, and tighten as necessary.
Grounding
• Pump: Connect a ground wire and clamp as shown
in FIG. 1. Loosen the grounding screw (W). Insert
one end of a 12 AWG (1.5 mm²) or thicker ground
wire (X) behind the grounding screw and tighten the
screw securely. Connect the clamp end of the
ground wire to a true earth ground. To order a
ground wire and clamp, order part number 222011.
FIG. 1: Ground Wire Connection
• Air and fluid lines: Use only conductive lines with a
maximum of 500 ft (150 m) combined line length to
ensure grounding continuity. Check electrical
resistance of lines. If total resistance to ground
exceeds 29 megohms, replace line immediately.
• Fluid supply container: Follow the local codes and
regulations.
• Pails for solvents and sanitizing solution used when
flushing: Follow local codes and regulations. Use
only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which
interrupts rounding continuity.
The equipment must be grounded to reduce the risk of
static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
