Tips:
►Before starting, tilt the pump to remove all air and wait 15 seconds.
►The bigger the flow, the wider the outlet should be.
►For greater flow, the water height should be lower. Also, use the 1.25-inch discharge port.
►If the water level is not high enough to start with automatic mode or you want to remove water as low as possible, you can switch to Manual control. Please make sure never to let the pump become dry running!
►If the auto mode doesn't work, please try your pump with a higher water level. The internal floater still works mechanically, it's not a chip sensor, so it may not be very precisely of ON/OFF level sometimes.
