SETUP
WARNING
To reduce the risk of serious bodily injury from static
sparking, fluid injection, or over pressurization and
rupture of the hose or gun, all hoses must be electri-
cally conductive, the gun must have a tip guard, and
each part must be rated for at least 2750 psi (195
bar) Maximum Working Pressure.
To avoid damaging the pressure control, which may
result in poor equipment performance and compo-
nent damage, follow these precautions:
1.
Always use grounded, flexible spray hose at
least 50 ft. (15 m) long.
2.
Never use a wire braid hose as it is too rigid to
act as a pulsation dampener.
3.
Never install any shutoff device between the fil-
ter and the main hose. See Fig 11–1.
4.
Always use the main filter outlet. Never plug this
outlet.
CAUTION
WARNING
Proper electrical grounding is essential to reduce
the risk of fire or explosion which can result in seri-
ous bodily injury and property damage. Read the
warning section FIRE OR EXPLOSION HAZARD
on page 5 for more detailed grounding
instructions.
NOTE: See Fig 11–1 while doing the setup.
1.
Fill the packing nut/wet-cup 1/3 full with Graco
Throat Seal Liquid (TSL), supplied.
2.
Connect the gun, 3 ft. hose and 50 ft. hose. Screw
the assembly onto the outlet nipple. Don’t use thread
sealant and don’t install the spray tip yet!
3.
Check the electrical service.
a. Electrical requirements: 120 V, 60 HzAC, 15
Amp (minimum).
b.
Use a grounded electrical outlet located at least
20 ft. (6 m) from the spray area.
b. Do not remove the grounding prong of the power
supply cord and do not use an adapter.
c.
Extension cord specifications: 15 Amps, 3 wires,
grounding type. (Long lengths reduce sprayer
performance.)
5. Plug in the sprayer. Turn the ON/OFF switch OFF.
Plug the cord into a grounded electrical.
6.
Flush the pump to remove the oil left in to protect
pump parts after factory testing. See the FLUSHING
GUIDELINES on page 15.
7.
Prepare the paint according to the manufacturer’s
recommendations. Remove any paint skin. Stir the
paint thoroughly. Strain the paint through a fine nylon
mesh bag to remove particles that could clog the filter
or spray tip.
