Before using the pump, please use the
screwdriver to toggle the fan blades to check
whether the electric pump rotates smoothly.
The electric pump shall be conducted test run
before use, and the time shall not exceed 10s
because long-time dry operation will damage the
mechanical seal. For three-phase electric pump,
you need to check whether the rotation direction
is consistent with the rotation mark. In case of
inverse rotation of the electric pump, you should
cut off the power immediately and adjust any two
phases of the three phases.
You should set drainage ditch around the
electric pump to form natural drainage to avoid
property damage due to water leakage when
using, repairing and replacing the water pump
(especially at the basement, kitchen, stairs and
other places).
The electric pump should be installed at places
where it is convenient for checking and
maintenance and be kept dry and ventilated.
When installing the electric pump at narrow
places, you should install it according to the
figure below and the fan housing must be at a
distance of over 25cm from the wall to facilitate
heat dissipation.
Y-shaped Filter
1. When first use it, please be sure to fill the pump
body with water and then plug in the power to
avoid dry operation without water.
2. Self-priming pumps can start with the pump
body filled with water, do not have to keep all
inlet pipes filled with water, and the inlet pipes of
non self-priming pumps must be filled with water
and exhaust all air in pipeline system.
For areas with high sand content, it
is advised to install a Y-shaped filter
at the inlet pipe to prevent the sand
from entering into the pump body
and causing wearing or blocking of
the impeller.
