2. Before using the pump, please use the screwdriver to toggle the fan blades to
check whether the electric pump rotates smoothly.

less than 10s, because long-time dry operation will damage the
mechanical seal. In case of a three-phase pump, please check
whether the rotational direction is the same as the rotation
marking. If the rotating direction of the electric pump is reversed,
immediately cut off the power supply and exchange any two
phases of the three-phase pump.

water level and do not let the bottom valve or the lower end of
the inlet pipe come out of water.
5. When installing the water inlet, please pay attention that the
height of the inlet pipe shall not exceed that of the inlet of the
pump, or it will cause the suction difficulty of the pump.
5.4 Additional recommended precations
1. If the user wants to have the electric pump controlled
automatically, a proper pressure control device shall be
installed on the outlet pipe.

ventilated place where repair and inspection can be
easily carried out. To install the electric pump at a
narrow place, please follow the diagram to the right
and keep the fan cover more than 25cm away from
the wall to improve heat dissipation.
