Prior to installation and use, please fully check
whether the Electric Pump is damaged during
transportation or storage, for example, whether any
cable or outgoing line or plug (if provided) is in a
perfect condition. In case of any damage, please
have a specialized person make replacement or
repair. The insulation resistance shall be greater than
50MΩ.
During installation, the complete
machine shall be fixed and the
inlet and outlet pipes shall be
separately supported, whose
weight shall not be completely
supported by the pump body.
1. Use a steel or rubber pipe (which shall not be too soft
so as to avoid becoming flat in case of absorption) to
connect the bottom valve and the inlet end of the Electric
Pump. Please make sure that the inlet pipeline and its
connections are sealed and present no air leakage.
2. Connect the outlet pipe firmly to prevent water from
splashing on the motor and hence causing electrical
leakage of the Electric Pump. When a rubber pipe is
used, pay attention to its temperature resistance limit to
ensure that the pipe will not be deformed by heat, for
such deformation might make the pipe become broken
and hence causing water leakage.
3. After connecting the upper end of the inlet pipe and the
inlet end of the Electric Pump, please make sure the end
of the inlet pipe, where the bottom valve and the strainer
lie, is submerged in water. To guarantee the reliable use
of the Electric Pump, please arrange an effective strainer
which, together with the bottom valve, shall keep more
than 30cm away from the water bottom, for the purpose
of preventing sludge or impurities from being absorbed to
the pump chamber and hence affecting the operation of
the pump.
4. Make a pipe as short as possible to reduce
connections. The drawing-up height shall not exceed the
suction lift.
1. During usage, pay attention to the decline of the water
level. Do not let the bottom valve or the lower end of the
inlet pipe come out of water.
2. When the inlet pipe is installed, please note that the
height of the inlet pipe shall not exceed that of the inlet
of the water pump, or otherwise it will be difficult for the
pump to absorb water.
