1) It is applicable to household water supply, equipment sup-
port, well water lifting, pipeline pressurization, garden watering,
vegetable greenhouse watering, fish farming and poultry
raising, etc.
2) Transfer clean water and other non-corrosive liquids with
low viscosity; do not transport inflammable, explosive, gasified
liquids and liquids containing solid particles or fibers. The PH
value should be within 6.5-8.5.
Remark:
This series of pump could be transformed into automatic water
pump, which is realized through external automatic plant that
is composed of pressure switch, pressure tank, etc. Function
features of the automatic pump are as follows: when the power
is on, turn on the water tap and the pump will start working
automatically; when the water tap is turned off, the pump will
stop working automatically. If a water tower is used along with
the automatic pump, connect to the upper limit switch and the
pump will start or stop working automatically with water level
in the water tower.

personnel who is proficient in this manual and has
special qualifications. Installation and operation should
be in accordance with local regulations and recognized
operation standards. Install pipelines properly as
stipulated in the manual and meanwhile conduct frost
protection measures for the pipeline.
4. Avoid splashing pres-
sured water to the electric
pump as well as prevent
the pump immersed by
water.
5. Keep the pump in
ventilation.
6. In case ambient temper-
ature is lower than 4°E or
the pump is not used for a
long time, empty liquid the
pipeline system to avoid
ice cracking of the pump
chamber. Do not operate
the pump for a long time
without water in it.
7. The pumped liquid
maybe hot and under high
pressure, before moving
and demounting the bump,
valves in both sides of the
bump should be turned off
first and then empty liquids
in the pump and pipelines
so as not to be scalded.
8. Do not transfer any
inflammable, explosive
or gasified liquids that
beyond the stipulation.
9. Ensure the pump will
not be accidently turned
on while installing and
maintaining; if not used
for a long time, cut off
the power first and then
tum off valves in inlet and
outlet of the pump.
10. Power supply should
be in accordance with
the voltage stated in the
nameplate. If not used
for a long time, put the

1. For pump installation, the inlet pipe should be as short as
possible with the least turnings. The pump should be installed
in ventilated and dry environment. It could be installed outside,
provided having proper covering to prevent rain and wind.
2. For pipeline use, valves should be installed on inlet and outlet
pipelines and the inlet pipeline should be installed with check
valve.
A. 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 (82);
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 (81).
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.
B. Installation Precautions of the outlet pipeline
1. 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.
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 ac-
cordance with power supply.
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.
3) In case the electric pump is used outdoor, extended lines
should apply rubber cables for outdoor use.

4) Check rotation of the motor (three-phase motor)
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 leads.
6) Automatic device
6.1) While using the automatic pump, in case it still operates
after turning off the water tap, lower down power cut-off pres-
sure of the pressure switch on the premise of pipeline without
leakage, namely, rotate the variable screw nut IJ in counter-
clockwise direction(-) to acquire lower Closed pressure.
6.2) In case the pump is often enabled when the water tap is
turned off (sometimes it is turned on and sometimes it is turned
off), check whether pipeline and the bottom valve have leakages
and pressure vessel pressure is normal, eliminate timely if any.
6.3) In case the pressure switch is alternately turned on or
turned off (frequent start) after turning on the water tap,
increase power cut-off pressure of the pressure switch, namely,
rotate the variable screw nut 1 in clockwise direction to acquire
higher cut-in pressure.
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.
Attention:
1) The pump chamber should be filled with water before first
use and water refilling is unnecessary in the future.
2) In case no water is discharged after being started for more
than 5 minutes with water filled, turn off the electric pump, re-
fill water or check whether the inlet pipeline has leakages.
3) In case of any frost and ice damages, please open the drain
plug to empty water in the pump chamber. When start up the
pump again, open the drain plug, fill water and tighten it and
then the pump is usable.
4) In case not use for a long time, water in the pump should
be emptied. The pump body, impeller and support should be
cleaned and coated with anticorrosive oil before they are put in
a ventilated and dry place for use.
5) In case the pump is halted for a long time, start it up again
according to above diagram.
6) In summer or when the ambient temperature is high, pay
attention to ventilation, avoid dew on electrical parts which will
result i1 electrical faults.
7) In case the motor is hot or abnormal, cut off the power im-
mediately and check faults according to the following table.
