Air and Fluid Line and Accessories

See Fig. 2 above.

WARNING

Three accessories are required in your system: an air shut-off valve/air bleed device, fluid drain valve, and ground wire. These accessories help reduce the risk of serious bodily injury, including fluid injection, splashing in the eyes or on the skin, injury from moving parts if you are adjusting or repairing the pump, and explosion from static sparking.

DThe air bleed device relieves air trapped between it and the air motor after the air supply is shut off. Trapped air can cause the air motor to cycle unexpectedly, causing serious injury if you are adjusting or repairing the pump. Use a bleed-type master air valve (J). Install them near the pump air inlet within easy reach from the pump.

DThe fluid drain valve (K) assists in relieving fluid pressure in the displacement pump, hoses, and dispensing valve. Triggering the valve to relieve pressure may not be sufficient.

DThe ground wire (B) reduces the risk of static sparking.

4.Install the air regulator (C) to control pump speed and pressure (see WARNING at left).

5.Install an air line filter (E) to remove harmful dirt and contaminants from your compressed air supply.

6.Install a second bleed-type master air valve (J) upstream from all other accessories, to isolate the accessories for servicing.

CAUTION

Do not hang the air accessories directly on the air inlet. The fittings are not strong enough to support the accessories and may cause one or more to break. Provide a bracket on which to mount the accessories.

NOTE: Install the air line accessories in the order shown in Fig. 2.

1.Install a pump runaway valve (G) to shut off the air to the pump if the pump accelerates beyond the pre-adjusted setting. A pump that runs too fast can be seriously damaged.

2.Install an air line lubricator (F) for automatic air motor lubrication.

3.Install a bleed-type master air valve (J) to relieve air trapped between the valve and the motor (see WARNING at left). Order Part No. 107142.
