System Accessories (continued)
WARNING
A bleed-type master air valve (E) is required in your
system. This accessory helps reduce the risk of
serious injury, including 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 air is
shut off. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
Order Part No. 114362.
Air Line Accessories
Install the following accessories in the locations shown
in Fig. 2, using adapters as necessary:
D A 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). Be sure the bleed valve is easily accessible from the pump, and is located
upstream from the air regulator.
D An air regulator (Z) adjusts air pressure to the
air–assisted gun.
D An air line filter (J) removes harmful dirt and
moisture from the compressed air supply. Also,
install a drain valve (W) at the bottom of each air
line drop, to drain off moisture.
D A second bleed-type air valve (K) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
D An Air Relief Valve (G) (Falcon II Packages only)
opens automatically to prevent over pressurization
of the pump.
Fluid Line Accessories
Install the following accessories in the locations shown
in Fig. 2, using adapters as necessary:
D A fluid filter (not shown) with a 60 mesh (250
micron) stainless steel element, to filter particles
from the fluid as it leaves the pump.
D A gun (S) dispenses the fluid. The gun shown in
Fig. 2 is an air–assisted spray gun for light to medium viscosity fluids.
D An air regulator (F) controls pump speed and out-
let pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
downstream from the bleed-type master air valve.
D A gun swivel (R) allows freer gun movement.
D A suction hose (T) allows the pump to draw fluid
from a supply container.
