Installation
The installations in Fig. 2 are guides for selecting and installing system components. Contact your Graco distributor for assistance in planning a system to suit your needs.
Mounting Automatic and Manual Models
Be sure the mounting surface can support the weight of the pump, surge suppressor, hoses, and accessories, and the stress caused during operation.
DMount the surge suppressor as close to the pump discharge as possible and upstream of equipment such as valves, meters, filters, and so on. The surge suppressor should be installed within 10 pipe diameters of the pump discharge.
DIf you use a flexible connector from the pump to the piping system, the surge suppressor should be mounted to the pump discharge manifold, and the flexible connector should be attached to the surge suppressor tee and system piping.
DBecause pressure is equal in all directions, the surge suppressor can be installed in any position, but the vertical position shown in Fig. 2 is recommended for better draining. Fluids with high specific gravity or high viscosity, settling of heavy material, and possible air entrapment further limit the mounting positions other than those shown in Fig. 2.
NOTE: When you mount a plastic surge suppressor, do not overtighten by using a large pipe wrench near the threads of the fluid inlet. The housing may crack if tightened too much. Hand tightening is recommended.

DThe air pressure to the surge suppressor must be greater than or equal to the pump discharge and/or system pressure. For equal air pressure, you can use a tee in the pump’s air supply line to run an air line to the surge suppressor.
DFor models with elastomer bladders, the tee must be located in the pump’s air supply line before any pump controller or instrumentation such as the filter, regulator, or pump control valve.
DFor models with PTFE bellows, the tee must be located in the pump’s air supply line after any pump controller or instrumentation such as the filter, regulator, or pump control valve.
