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:

DA 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 eas- ily accessible from the pump, and is located upstream from the air regulator.

DAn 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.

DAn air regulator (Z) adjusts air pressure to the air–assisted gun.

DAn 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.

DA second bleed-type air valve (K) isolates the air line accessories for servicing. Locate upstream from all other air line accessories.

DAn 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:

DA fluid filter (not shown) with a 60 mesh (250 micron) stainless steel element, to filter particles from the fluid as it leaves the pump.

DA gun (S) dispenses the fluid. The gun shown in Fig. 2 is an air–assisted spray gun for light to me- dium viscosity fluids.

DA gun swivel (R) allows freer gun movement.

DA suction hose (T) allows the pump to draw fluid from a supply container.
