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. . Mount 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. . If 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. . Because 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. Connecting Automatic Models Connecting Manual Models . Connect the 1/4-in air supply hose to the 1/4 npt connection on the top of the surge suppressor. . Connect the 1/4-in air supply hose to the brass one-way check valve on the top of the surge sup. The air pressure to the surge suppressor must be pressor. 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. . The air pressure to the surge suppressor must be greater than or equal to the pump discharge and/or . For models with elastomer bladders, the tee must system pressure. For equal air pressure, you can be located in the pump’s air supply line before any use a tee in the pump’s air supply line to run an air pump controller or instrumentation such as the line to the surge suppressor. filter, regulator, or pump control valve. . For models with PTFE bellows, the tee must be located in the pump’s air supply line after any pump . The tee must be located in the pump’s air supply controller or instrumentation suc...
