All models with a plug-in power cords system should still have a qualified electrician inspect the outlet being used to ensure proper wiring. Grounding Grounded Blade Outlet Power Cord Switch Cord Figure 3 TESTRESET The control switch is a wide-angle system which prevents short cycling of the pump motor and the consequential problems that short cycling can cause. The switch can be mounted on the discharge pipe (just above the pump discharge flange). See illustrations for switch mounting arrangements. 2 3 Installation (Continued) INSTALLATION BASICS: 1. NEVER lift this product by the electrical cords. 2. Install pump in a sewage pit that fulfills the minimum size requirements (24 in. minimum). Construct sump pit of tile, concrete, steel or plastic. Do not install a pit smaller than recommended. 3. The unit should be located and rest on a solid, level foundation. Do not place pump directly on clay, earth, gravel or sandy surface. These surfaces contain small stones, gravel, sand, etc. that may clog or damage the pump and cause pump failure. Flood risk. If fl exible discharge hose is used, make sure pump is secured in sewage pit to prevent movement. Failure to secure pump could allow pump movement and switch interference and prevent pump from starting or stopping. 4. Thread the discharge pipe or pipe nipple into the discharge flange connection. 5. A check valve MUST be used in a solids-handling system. Mount the check valve in a horizontal position or at a 45. angle with the valve pivot on top. In a vertical position, solids tend to lodge on the valve flapper and can prevent it from opening. 6. Drill a 1/8 in. hole in the discharge pipe 1 to 2 inches above the flange. This will prevent air locking and loss of prime at startup. A gate valve should be installed in the system after the check valve. This gate valve should be a full port valve which will pass 2 in. solids or as required by state and local codes. The gate valve permits removal of the pump and/ or the check valve for servicing (and will minimize back-flow mess). 7. (OPTIONAL) Install a union between the check valve and the pump so the pump can be removed with the least amount of disturbance of the piping. 8. Connect 2 in. rigid pipe to check valve. Support pump and piping when assembling and after installation. Failure to do so could cause piping to break, pump to fail, etc. which could result in property damage and/or personal injury. 9. Protect electrical cord from sharp objects, hot surfaces, oil and chemicals. Avoid kinking the cord and replace damaged cords immediately. IMPORTANT: Make sure there is adequate room for tether switch to swing freely during operation. 10. A pit cover must be installed to prevent debris from clogging or damaging the pump. All piping and power cords will be brought through the appropriate openings in the basin cover. Do not modify existing openings in any way. All sewage basins must be vented to prevent a build-up of methane gas. Consult your local codes for proper venting. DO NOT install venting in locations classifi ed as hazardous in accordance with the National Electrical Code NFPA 70. Operation Always disconnect the power source before attempting to install, service, relocate or maintain the pump. Never touch sewage pump, pump motor, water or discharge piping when pump is connected to electrical power. Never handle a pump or pump motor with wet hands or when standing on wet or damp surface or in water. Fatal electrical shock could occur. 1. Verify pump and switch operate within the basin. Risk of electrical shock! This pump is supplied with a grounding conductor and grounding type attachment plug. Use a grounded receptacle to reduce the risk of fatal electrical shock. Never cut off the round grounding prong. Cutting the co...
