Supplied Components
See FIG. 1. Components vary by package ordered.
See tables on pages 6 to 7. Your package may include:
• The red-handled bleed-type master air valve (U) is
required in your system to relieve air trapped
between it and the air motor and gun when the valve
is closed.
Do not block access to the valve.
• The pump air regulator (X) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump.
• The air relief valve (not shown) opens automatically
to prevent overpressurization of the pump.
• The gun air regulator (T) adjusts the air pressure to
the air-assisted spray gun (H).
• The air-assisted or airless spray gun (H) dispenses
the fluid. The gun houses the spray tip (not shown),
which is available in a wide range of sizes for differ-
ent spray patterns and rates of flow. Refer to gun
manual for tip installation.
• The hose bundle (L) supplies fluid (and air for AA
guns) to the gun, and allows recirculation of fluid
when the gun is not triggered.
• The gun swivel (J) allows for freer gun movement.
• The suction hose (N) with strainer (P) allows the
pump to draw fluid from a 5 gallon (19 liter) pail.
• A fluid filter (F) with a 60 mesh (250 micron) stain-
less steel element filters particles from fluid as it
leaves the pump.
• DataTrak (V) provides pump diagnostics and mate-
rial usage information. See page 19.
• The back pressure regulator (E) controls pressure
back to the gun and maintains proper circulation
pressure.
• The 3-way valve (M) allows choice to circulate fluid
back to the pump or return it to the supply container.
• A fluid drain valve (G) relieves fluid pressure in the
hose and gun.
•The fluid heater (D) heats the fluid as it passes
through, to maintain the correct spraying viscosity.
Read and understand all instructions in the supplied
heater manual 309524 before operating the heater.
Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from splash-
ing or moving parts.
Heat causes fluid to expand. If the heated fluid is
trapped with nowhere to expand, it can cause compo-
nent rupture. Be sure to keep the heated fluid circulat-
ing (turn the 3-way valve to CIRC). Do not install a
fluid shutoff device between the heater and the gun.
