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
2750 psi (195 bar) Working Pressure. This
is to reduce the risk of serious bodily injury caused
by static sparking, fluid injection or over–pressuri-
zation and rupture of the hose or gun.
CAUTION
To avoid damaging the pressure control, which may
result in poor equipment performance and compo-
nent 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. 1.
1.
Connect the hose (B) and gun (C)
and screw it
onto the outlet nipple (A).
Don’t use thread sealant,
and don’t install the spray tip yet!
2.
Fill the wet–cup (D).
Pry off the wet–cup seal. Fill
the cup 1/3 full with Graco Throat Seal Liquid
(TSL) (68) supplied. Install the seal.
3.
Check the electrical service.
Be sure it is 120 V,
60 HzAC, 15 Amp (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 ga recommended), 15 amp ex-
tension cord.
NOTE:
Long extension cord lengths affect sprayer
performance.
4.
Plug in the sprayer.
Be sure the ON/OFF switch
(E) is OFF. Plug the cord into a grounded outlet at
least 20 ft. (6 m) away from the spray area.
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. Also read
FIRE OR EXPLOSION HAZARD
