Installation

Mounting

Mount the pump securely so that it cannot move around during operation. Failure to do so could result in personal injury or equipment damage.

1.Plan the mounting layout for easy operator access to the pump air controls, sufficient room to change drums and a secure mounting platform.

2.If using a follow plate (H), remove the drum cover. Scoop the material to the center of the drum. Place the plate on the material. Guide the pump foot valve through the plate.

3.Mount the pump to the drum cover or other suitable mounting device.

4.For ease in changing drums, install a pump eleva- tor.

Air and Fluid Line Accessories

Refer to FIG. 2 for the following instructions.

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 yes or on the skin, injury from moving parts if you are adjusting or repair the pump, and explosion from static sparking.

•The air bleed device relieves air trapped between it and air motor after the air supply is shut off. Trapped air can cause the 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.

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

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

NOTICE

Do not hand 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. Provides a bracket on which to mount the accesso- ries.

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

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.

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

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

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