2. Prior to the use of the electric pump, please carry out a test
run, the duration of which shall not exceed 10s, as long-time dry
run 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.
3. During usage, please pay attention to the decrease of the
water level and do not let the bottom valve or the lower end of
the inlet pipe come out of water.
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.
2. Install the electric pump in a dry and well-
ventilated place where repair and inspection can be
easily carried out. To install the electric pump at a
narrow place, please follow the diagram and keep
the fan cover more than 25cm away from the wall to
improve heat dissipation.
