Setup - Graco 223-773 A Series Instructions And Parts List

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 (21.0 MPa, 210 bar) Working
Pressure . This is to reduce the risk of serious inju-
ry 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
filter and the hose. See Fig. 2.
1. Assemble the gun (L), 3 ft. whip hose (N) and
50 ft. hose (J). Don't install the spray tip and tip
guard yet.
2. Two gun hookup. Remove the cap (12) from the
1/4 npsm(m) secondary hose outlet and attach a
minimum 50 ft. long hose. For more flexible gun
movement, install a 3/16 in. ID, 3 ft. whip hose be-
tween the main hose and the gun.
3. Fill the packing nut/wet–cup (216) 1/3 full with
Graco Throat Seal Liquid (TSL), supplied.
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. Also read FIRE OR
EXPLOSION HAZARD on page 4.

Setup

4. Check the electrical service. Be sure the electri-
cal service is 120 VAC, 60 Hz, 20A. Use a properly
grounded outlet. Do not remove the grounding
prong of the power supply cord. Do not use an
adapter. Extension cords must have 3 wires of a
minimum 12 gauge size. Long extension cords
reduce sprayer performance. If 20A service is not
available, flip the 15/20 Amp switch (U) to 15 set-
ting to avoid nuisance tripping of circuit breakers.
5. With the the ON/OFF switch OFF, plug the cord
into a grounded electrical outlet located at least
20 ft. (6 m) away from the spray area.
6. Flush the pump to remove the lightweight oil
which was left in to protect pump parts after fac-
tory testing. See page 9.
