User manual GRACO HUSKY LEAK 308702E

[. . . ] D Pipe and dispose of the exhaust air safely, away from people, animals, and food handling areas. Take precautions to avoid acid or acid fumes from contacting the pump housing exterior. Stainless steel parts will be damaged by exposure to acid spills and fumes. FIRE AND EXPLOSION HAZARD Improper grounding, poor ventilation, open flames, or sparks can cause a hazardous condition and result in a fire or explosion and serious injury. D Never use a polypropylene pump or leak detector with non-conductive flammable fluids as specified by your local fire protection code. [. . . ] When the leak detector triggers a pump shutdown, you should suspect that a pump diaphragm has failed, and you should respond as follows: 1. Shut off all air to the pump and the leak detector. 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, 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. Open the fluid drain valve to relieve all fluid pressure, and have a container ready to catch the drainage. 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 that are compatible with the equipment wetted parts. Drain the liquid from the leak detector through the drain valve (B) into a suitable container, depending on the liquid being pumped. If the liquid that comes out of the drain valve (B) is only water condensation, no corrective action is necessary. Close the drain valve, open the fluid supply line, and resume pumping. If the liquid being pumped comes out of the drain valve (B), repair the pump immediately to minimize internal damage to the pump. See Cleanup After a Leak. WARNING FIRE AND EXPLOSION HAZARD Never pump flammable fluids with polypropylene units. Such use could cause a fire or an explosion. Cleanup After a Leak If a spill occurs with tacky or viscous fluid, the fluid could solidify and interfere with the action of the moving parts. It is recommended that you check the following parts for cleaning or replacement any time the leak detector is activated (See Parts Drawing on page 13): D D D D D D Concentrator (3) Float (4) Push rod (5) Compression nut (6) Converter o-ring (12) Drain valve (B) 8 308702 Maintenance For instructions on cleaning the inside of the leak detector and performing an actuator valve test, see Routine Cleaning and Test on page 10. For a function test that does not involve any disassembly, perform the following steps (See Parts Drawing on page 13): 1. Relieve the pressure, and turn off the air supply to the pump and the leak detector. If the pump operates, the the leak detector actuator valve (M) may be defective and may need to be replaced. Shut off air to pump and leak detector, drain water out of leak detector by opening the drain valve (B), turn air back on, and resume pumping. 308702 9 Service Routine Cleaning and Test See the Parts List on page 13. Relieve the pressure, and disconnect the compressed air supply to the pump and leak detector. To test the leak detector, connect an air line to the leak detector air line fitting (10), and disconnect the vinyl tube (2) at the pump shut-off valve (1). To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. Flush the inside of the leak detector with water or a cleaner compatible with the liquid that has been pumped. Air should stop flowing through the shut-off valve tube (2) and be redirected to flow out the alternate air outlet. If air does not stop flowing, the leak detector actuator valve (M) is defective and needs to be replaced.
