Water-level control mode
a. When the pump is power on, if floating switch (or water-level detector) is "ON", it means the pump starts to
work.
b. In the running of the pump, if floating switch (or water-level detector) is "OFF", it means the pump will stop
working after 60 s continuous working, but if floating switch (or water-level detector) is "ON" again in 60 s after
"OFF", the pump will be non-stop.
c. Stop time: After the pump stops for low water-level, it will not start within 60 s, even if floating switch (or water-
level detector) is ON, unless plug in the power again after power off.
d. Recovery mode: The pump stops for low water-level, it will start when floating switch (or water-level detector)
is ON.
