Supplied Components
Refer to Fig. 1.
WARNING
A red-handled bleed-type master air valve (E) and
a fluid drain valve (F) are supplied. These compo-
nents help reduce the risk of serious injury, includ-
ing fluid injection and splashing of fluid in the eyes
or on the skin, and injury from moving parts if you
are adjusting or repairing the pump.
The bleed-type master air valve relieves air trapped
between this valve and the pump after the valve is
closed. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient.
D The red-handled bleed-type master air valve (E)
is required in your system to relieve air trapped
between it and the air motor when the valve is
closed (see the WARNING above). Do not block
access to the valve.
D The pump air regulator (G) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump.
D The air relief valve (H) opens automatically to
prevent overpressurization of the pump.
D The air inlet swivel (K) connects incoming air to
the pump.
Installation
D The suction hose (30) and tube (33) allow the
pump to draw fluid from a 55 gallon (200 liter) drum
(L). Carbon steel models include a bung adapter
(34) which screws into the drum's bung hole.
D The fluid heater (50) 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.
D The fluid filter (15) includes a 60 mesh (250
micron) stainless steel element to filter particles
from the fluid as it leaves the pump. It also includes
the fluid drain valve (F), which is required in your
system to relieve fluid pressure in the hose and gun
(see the WARNING at left).
D The fluid hose (101) consists of two hoses in a
sheath, connected to a manifold (102) and a whip
hose (103). Fluid is supplied to the gun by the fluid
supply hose (101a) and the whip hose (103). Un-
used fluid is returned to the back pressure regulator
(46) through the fluid return hose (101b).
D The airless spray gun (106) dispenses the fluid.
The gun houses the spray tip (107), which is
available in a wide range of sizes for different spray
patterns and rates of flow.
D The back pressure regulator (46) controls back
pressure to the gun and maintains proper circula-
tion pressure.
D The 3-way recirculation valve (28) receives fluid
from the back pressure regulator and recirculates it
to the pump or to the fluid container, as desired.
