- Connect Discharge Hose: Attach a standard 3/4" garden hose to the pump's 3/4" NH outlet. Ensure the connection is tight to prevent leaks. Do not overtighten the elbow fitting if used, as it may break.
- Position Pump: Place the pump in the area to be drained, ensuring it is fully submerged in water. The integrated strainer at the base will filter debris.
- Route Power Cord: Position the battery enclosure in a dry, accessible location, away from the water source, using the 15.4ft extension cord.
