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 Know the specific hazards of the fluid you are using. D Store hazardous fluid in an approved container. 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.
Installation Grounding WARNING FIRE AND EXPLOSION HAZARD When pumping flammable fluids, the surge suppressor must be grounded. Before pumping, ground the system as explained below. Also read the section FIRE OR EXPLOSION HAZARD on page 3. Polypropylene surge suppressors are not conductive. Attaching the ground wire to the grounding lug grounds only the clamp or flange (see Fig. 1).
Installation Grounding a Surge Suppressor A B H S T W Husky pump Husky surge suppressor Fluid drain valve (required) Dispense valve Fluid drain line Surge suppressor ground wire (required) See page 4 for installation instructions. Y Air motor ground wire (required) Z Container ground wire (required) 1 air supply connection 1 Hose must be conductive. H B 2 Dispense valve nozzle must be in contact with the container.
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.
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 D D D D 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.
Operation Charging and Startup For optimum performance, surge suppressors should be charged to a pressure 2 to 10 psi (0.01 to 0.07 MPa, 0.1 to 0.7 bar) lower than system pressure. Manual Models Automatic Models CAUTION Automatic surge suppressors must have the air supply connected before you start pumping. Failure to do so could result in the internal air valve puncturing or rupturing the bladder. CAUTION Manual surge suppressors must be charged before you start pumping.
Troubleshooting Relieve the pressure before checking or servicing the equipment. WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 7. Check all possible problems and causes before disassembling the pump. PROBLEM CAUSE SOLUTION Surge suppressor does not hold pressure.
Service Bladder Failure Replacing Bladder or Bellows 1. Relieve the pressure. 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: D Chemical attack: Check chemical compatibility charts. Consult your Graco distributor. D Cut bladder or bellows: Check for sharp objects that may have been introduced into the surge suppressor through pumped fluid.
Service Torque Table Find the proper torque specifications for your surge suppressor unit in the table below. These are the torques to which the clamp band, ring flange, or bolts in bolted units need to be tightened.
