Look after your pump to ensure it has a long life
Only connect equipment that was provided by the manufacturer or
supplier to this pump.
Do not try to power the pump from batteries, generators or a grid
connection.
Keep the controller out of water or direct rain, this reduces the
chances of short circuit of cable connections.
Do not disconnect the cables when the pump is running. First turn off
the pump then disconnect the cables.
Do not let the pump run dry.
Pump water that is free from solid objects like sand, sticks or weed.

•Input A1 or A2 is activated, check the LED status
•Wiring problem: plugs not inserted correctly or wet
•The pump is clogged with mud or sand
•Hose or pipe is blocked/ twisted
•The water temperature is too high/ Pump was laying in the sun
and heated up
•The controller is too hot and needs to cool down
