Installation, System Accessories

Installation

A bleed-type master air valve (D) and a fluid drain valve (E) are required in your system, to help reduce the risk of serious injury, including splashing fluid in the eyes or on the skin, and injury from moving parts when you are adjusting or repairing the pump.

The bleed-type master air valve (D) relieves air trapped between this valve and the pump after the pump is shut off. Trapped air can cause the pump to cycle unexpectedly and result in serious injury, including amputation. Install the valve close to the pump.

The fluid drain valve (E) helps relieve pressure in the displacement pump, hose, and dispensing valve when shutting off the pump. Actuating the dispensing valve to relieve pressure may not be sufficient, espe- cially if there is a clog in the hose or the dispensing valve.

System Accessories

To ensure maximum pump performance, be sure that all

accessories used are properly sized to meet your sys- tem’s requirements. See Accessories, page 20.

Air Line Accessories

Install the following accessories in the order shown in the Typical Installation for Lubrication Applications,

using adapters as necessary:

An air line lubricator (B) provides automatic air motor lubrication.

A bleed-type master air valve (D) is required in your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING on left). Be sure the bleed valve is easily accessible from the pump, and is located downstream from the air regu- lator.

An air line filter (C) to remove harmful dirt and moisture from the compressed air supply.

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

Fluid Line Accessories

A fluid drain valve (E) is required in your system to relieve fluid pressure in the hose and gun (see the WARNING on left). Install the drain valve so that it points down and the handle points up when the valve is opened.
