B: INSTALLATION PRECAUTIONS FOR INLET PIPELINES
1) While installing the electric pump, do not use too soft rubber
tube for the inlet pipeline, avoiding to be sucked flat.
2) The foot valve should be vertically placed and installed 30cm
from water bottom to avoid sucking in sands and stones (B2);
3) Joints of the inlet pipelines should be sealed with the least
elbows, no water can be sucked.
4) Diameter of the inlet pipe should be at least in accordance
with that of the water inlet, so as to avoid too much water loss
which will influence outlet performance.
5) Pay attention to drop of water level while using, the foot valve
should not be above the water surface (B1).
INCORRECT INSTALLATION DIAGRAM
6) In case the inlet pipe is longer than 10m or its lifting height
exceeds 4m, the pipe diameter should exceed diameter of water
inlet of the pump.
7) Ensure the pumped will not be affected by pipeline pressures
while installing the pipelines.

8) Filter should be installed in inlet pipelines so as to avoid solid
particles to enter into the electric pump.
C: INSTALLATION PRECAUTIONS OF THE OUTLET PIPELINE
Pipe diameter of the outlet pipeline should be at least in
accordance with that of the water outlet, so as to reduce
its voltage drop, high flow rate and noise to the minimum.
8. Electrical Connection
Unless the power is off, do not wiring the
junction box. The electric pump should have
reliable grounding to prevent current leakage with
leakage protection switch being equipped.
8.1 Electrical connection and protection should be conducted
according to stipulations. Specification of working voltage
is marked on the nameplate; please ensure the motor is in
accordance with power supply.
8.2 In case the working area of the electric pump is too far
from the power supply, power transmission lines should be of a
heavier gauge, otherwise the electric pump cannot work
normally because the voltage drop is too dramatic.
8.3 A rubber extension cable shall be applied for the electric
pump in case of outdoor use.
8.4 Check rotation of the motor (three-phase motor).
8.5 Check whether operation of the electric pump is normal,
rotation is correct, which could be observed from the fan blade
terminal, e.g. clockwise rotation means correct direction. In case
the rotation is incorrect, cut off power and exchange the two
power cables.

9. START-UP AND MAINTENANCE
Do not start up the pump before the pump chamber is
filled with water.
Do not touch the electric pump unless its power has
been cut off for at least 5 minutes.
Do not dismount the pump body unless water in the
pump chamber is empted.
Rotate the fan blade before startup, check whether the pump
rotation is flexible and then unscrew the water-filling plug, fill
