Safety Instructions Save these instructions - This manual contains important safety and operating instructions for the NexPump. Follow these important safety precautions. Failure to follow safety precautions can result in personal injury or damage to the NexPump. CAUTION - To reduce the risk of injury, charge only lead type rechargeable batteries. Other types of batteries may burst causing personal injury and damage. Do not expose the NexPump system unit to rain or snow.
NEVER smoke or allow a spark or flame in the vicinity of the battery. Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or another electrical part that may cause an explosion. Remove personal metal items such as rings, bracelets, necklaces and/or watches when working with a battery. A battery can produce a short circuit current high enough to weld a ring (or the like) to metal, causing a severe burn.
Never allow other items that discharge into the sump pit to be unsecured. Unsecured items such as garden hoses, laundry hoses and other medium used to discharge water may interfere with the NexPump pumps or sensors. Be sure to secure all items that may be used to discharge water into the sump pit and verify that secured items will not interfere will any NexPump operations. Installation Procedures Installing the NexPump does require some plumbing expertise.

IMPORTANT: If a vent hole is drilled in the discharge pipe make sure a sensor or sensor clamp does not block the vent hole. Do not position the sensor on the side of the discharge pipe facing the drain tile or any incoming rush of water. Step 2: Secure Wires Secure the pump and sensor wires to discharge pipes with nylon wire ties.
