D When compressed air is applied to the pump and the leak detector, the pump operates as it would under normal operating conditions. Exhaust air from the pump flows into the leak detector and out of the leak detector silencer (R). D If the pump diaphragm leaks, liquid may enter the pump's air exhaust and be carried to the leak detector. When liquid accumulates in the leak detector, the float (4) rises, and air flow is diverted to a different hose in the the three-way valve (M). As a result, air pressure is removed from the shut-off valve (1), which closes it and stops the pump. 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. Refer to the Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer's warnings. 2. 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. Additionally, the leak detector must be serviced. 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.
