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 such as the filter, line before any pump controller or instrumentation regulator, or pump control valve. such as the filter, regulator, or pump control valve. . . Operation Pressure Relief Procedure WARNING PRESSURIZED EQUIPMENT HAZARD The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the dispensing device, or splashing fluid, follow this procedure whenever you . Are instructed to relieve pressure . Stop pumping . Check, clean, or service any system equipment . Install or clean fluid nozzles 1. Stop pumping, and shut off the air to the pump. 2. Relieve pressure in the surge suppressor as follows: . For automatic surge suppressors, remove the air pressure gauge, and allow any residual air pressure to escape. . For manual surge suppressors, adjust the regulator to relieve the air pressure by dialing down the pressure. WARNING . . TOXIC FLUID HAZARD Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed. Read TOXIC FLUID HAZARD on page 3. Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings. WARNING FIRE AND EXPLOSION HAZARD Charge the surge suppressor with compressed air or nitrogen only. Do not use oxygen. Never pump flammable fluids with polypropylene units. Charging the surge suppressor with oxygen or pumping flammable fluids with polypropylene units could cause a fire or an explosion. Minimum and Maximum Operating Temperatures Find the minimum and ...
