Air Line; Fluid Line Accessories; Flush Before Using Equipment - Graco XP70 Instruction & Parts Manual

Air Line

Bleed-type master air valve (CA): required in your sys-
tem to relieve air trapped between it and the air motor
when the valve is closed.
Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from splash-
ing or moving parts.
• Be sure the valve is easily accessible from the pump
and located downstream from the air regulator.
• Pump air regulator (CB): to control pump speed
and outlet pressure.
• Air line filter (C): 40 micron filter that removes
harmful dirt and moisture from compressed air sup-
ply. Accumulated water is automatically drained
from the filter.

Fluid Line Accessories

• Fluid Manifold (AA): mounts fluid gauges and over
pressure relief valves. Controls circulation and
pump priming.
• Mix Manifold (AB): brings A and B fluid together.
Provides control and check valves for A, B, and flush
fluids.
• Circulation Handle (AC): open to relieve fluid pres-
sure, prime pumps, and circulate material in hop-
pers. Close to spray mixed material.
• Dual Shutoff Handle (AE): Controls A and B on/off
flow into mix manifold. Press down to provide A and
B fluid to the mix manifold and into the static mixer
for spraying. Press up to turn off A and B before
flushing the mixed material.
• Solvent Flush Valve (AD): to flush solvent through
mix manifold, hose, and spray gun.
• Static mixer/gun hose kit: to mix the two fluids and
deliver mix to the spray gun. Includes static mixer
and hoses to the spray gun.

Optional Accessories
• Optional Fluid Heaters (N): to heat the resin and
hardener before mixing. Improves the chemical
reaction and lowers viscosity to improve the spray
pattern.
• Optional Solvent Flush Kit (G): to flush the mix
manifold. Includes a solvent pump, mounting hard-
ware, and solvent supply hose.

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Empty and Flush Entire System (new sprayer or end
of job), page 27.
