Setup
WARNING
If you supply your own hoses and spray gun, be
sure the hoses are electrically conductive, that the
gun has a tip guard, and that each part is rated for
at least
3000 psi (210 bar, 21 MPa) Working Pres
-
sure. This is to reduce the risk of serious injury
caused by static sparking, fluid injection or over–
pressurization and rupture of the hose or gun.
CAUTION
To avoid damaging the pressure control, which
may result in poor equipment performance and
component damage, follow these precautions:
1.
Always use a nylon 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
pump and the hose.
See Fig. 2.
4.
Connect the hose and gun and screw it onto the
outlet nipple (F).
Don’t use thread sealant, and
don’t install the spray tip yet!
5.
Fill the wet–cup (L). Pry off the wet–cup seal. Fill
the cup 1/3 full with Graco Throat Seal Liquid
(TSL) (68) supplied. Install the seal.
6.
Check the electrical service. Be sure it is
120 VAC, 60 Hz, 15A (minimum). Use a properly
grounded outlet. Do not remove the third (ground-
ing) prong of the power supply cord, and do not
use an adapter.
Use a 3-wire (12 AWG recommended), 15A exten-
sion cord.
NOTE: Long extension cord lengths affect sprayer
performance.
7.
Plug in the sprayer. Be sure the ON/OFF switch
(C) is OFF. Plug the cord into a grounded outlet at
least 20 ft. (6 m) away from the spray area.
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. Also read FIRE OR
EXPLOSION HAZARD on page 4.
