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. Dispose of hazardous fluid according to all local, state and national guidelines. D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer. [. . . ] D The 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. D For 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. D For 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.
Connecting Manual Models
D Connect the 1/4-in air supply hose to the brass one-way check valve on the top of the surge suppressor.
D The 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.
D 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.

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 D D D D Are instructed to relieve pressure Stop pumping Check, clean, or service any system equipment Install or clean fluid nozzles

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. D Use fluids and solvents which are compatible with the equipment wetted parts. Generally, pulsation is most effectively minimized when the air supply to the surge suppressor is regulated to 2 to 10 psi (0. 01 to 0. 07 MPa, 0. 1 to 0. 7 bar) lower than system pressure.
NOTE: Automatic surge suppressors are not recommended for use as suction stabilizers at the pump inlet or as a surge suppressor at a quick-closing valve. Adjustable surge suppressors should be used for such applications.

Troubleshooting
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 7. CAUSE Manual or automatic models: Leaking threaded connections Loose flange bolts or clamp Failed bladder or bellows Blocked air line to unit Automatic models only: One-way valve at air inlet is installed backwards. Manual models only: Faulty regulator Dampening effect of surge suppressor is not sufficient. Relieve the pressure before checking or servicing the equipment.
Check all possible problems and causes before disassembling the pump. Check regulator.
Surge suppressor installed incorrect Surge suppressor should be distance from pump installed within 10 pipe diameters of pump discharge. Surge suppressor pressure should be 2 to 10 psi (0. 01 to 0. 07 MPa, 0. 1 to 0. 7 bar) lower than system pressure. Remove pressure from surge suppressor, and check automatic valve for proper operation as follows: 1. Fill top of surge suppressor with enough water to cover automatic valve. Failed bladder or bellows Surge suppressor too small for pump Automatic models only: Plugged automatic valve
There is leaking around surge suppressor fluid inlet.
PTFE sealing tape or paste is needed on threads of fluid inlet.
Service
Bladder Failure
Normal life for bladders can be from a few months to several years, depending upon the harshness of the application. Below are common reasons for failed bladders or bellows:
Replacing Bladder or Bellows
1. Relieve the pressure.
