Installation
Grounding
Pump:
use ground wire and clamp (supplied). Loosen
grounding lug locknut (LL) and washer (LW). Insert one
end of a 1.5 mm
2
(12 ga) minimum ground wire end
(GW) into lug (LS) slot and tighten locknut securely.
Connect ground clamp to a true earth ground. Order
part 237569 ground wire and clamp.
Air and fluid hoses:
use only electrically conductive
hoses. Check electrical resistance of hoses. If total
resistance to ground exceeds 29 megaohms, replace
hose immediately.
Air compressor:
follow manufacturer’s
recommendations.
Spray gun:
ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container:
follow local code.
Object being sprayed:
follow local code.
Solvent pails used when flushing:
follow local code.
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
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure:
hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Accessories
Install the following accessories in the order shown in
F
. 1, page 7, using adapters as necessary. Contact
your Graco representative or Graco Technical
Assistance for assistance in designing a system to suit
your 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. F
. 1, page 7, illustrates a wall mount system.

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