Setup - Graco 231–373 Instructions-Parts List Manual

WARNING
To reduce the risk of serious injury from static
sparking, 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 3000 psi (210 bar)
Maximum Working Pressure.
CAUTION
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 filter
and the main hose. See Fig. 2.
4. Always use the main filter outlet for one gun op-
eration. Never plug this outlet.
WARNING
FIRE AND EXPLOSION HAZARD
Proper electrical grounding is essential
to reduce the risk of fire or explosion
which can result in serious injury and
property damage. Read the warning sec-
tion FIRE OR EXPLOSION HAZARD on
page 6 for more detailed grounding
instructions.

Setup

NOTE: See Fig. 2 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. Two gun hookup. Unscrew the cap from the 1/4
npsm(m) secondary hose outlet. Connect a hose
and gun to the outlet. Use a 1/4 in. ID, 50 ft. long
(minimum) main hose. For more flexible gun
movement, install a 3/16. ID, 3 ft. hose between
the main hose and the gun.
4. Check the Electrical Service.
Two gun hookup. Unscrew the cap from the 1/4
npsm(m) secondary hose outlet. Connect a hose
and gun to the outlet. Use a 1/4 in. ID, 50 ft. long
(minimum) main hose. For more flexible gun move-
ment, install a 3/16 in. ID, 3 ft. hose between the main
hose and the gun.
a. Electrical requirements: 120 V AC, 60 Hz, 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
outlet.
6. Flush the pump to remove the oil left in to protect
pump parts after factory testing. See Flushing
on page 12.
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 (available at most paint dealers)
to remove particles that could clog the filter or
spray tip. This is an important step for trouble-free
paint spraying.
