NOTE: To ensure the maximum pump performance and safety, be sure that all the accessories used are properly sized to meet your system requirements and the pressure limits of the pump. Use only genuine Graco parts and accessories.

In the air line, install an air filter (F) to remove harmful dirt and moisture from the compressed air supply. Install an air line lubricator (H) downstream from the air filter, the air regulator (B) and the bleed-type master air valve (A). A lubricator will provide automatic lubrication to the air motor.

WARNING

A bleed-type master air valve (A) is required in your system to relieve the air trapped between the valve and the pump after the pump is shut off. Trapped air can cause the pump to cycle unexpectedly, resulting in possible serious injury, including amputation.

Connect the Air Supply Line

Connect an electrically conductive air supply hose to the 3/4” npt(f) port of the air manifold (B). Open the bleed-type master air valve (A) and, using the pressure gauge, set the air regulator (B) to the desired pressure. See the Typical Installation and the Parts Drawing.

Pressure Relief Valve

All components have rated working pressures of 5000 psi (345 bar) or greater. For more information about the pressure relief valve, see instruction manual 308547.
