Air and Fluid Line and

Accessories

See FIG. 2.

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 skin 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.

•The 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 unex- pectedly, causing serious injury if you are adjusting or repairing the pump. Use a bleed-type master air valve (J), installed near the pump air inlet within easy reach from the pump.

•The fluid drain valve (K) assists in relieving fluid pressure in the displacement pump, hoses, and dis- pensing valve. Triggering the valve to relieve pres- sure may not be sufficient.

•The ground wire (B) reduces the risk of static spark- ing.

Installation

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.

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. Order Part No. 107142.

4.Install an air regulator (C) to control pump speed and pressure.

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.
