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 demount-
ing 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
turn off valves in inlet and
outlet of the pump.
10. Power supply should be in

4. PIPELINE INSTALLATION
This product should be installed and
maintained by personnel who is procient in
this manual and has special qualications.
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.
4.1 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.
4.2 For pipeline use, valves should be installed on inlet and
outlet pipelines and the inlet pipeline should be installed with
check valve.
Max. water temperature: + 60
Min. Water temperature: +4

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).
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.
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.
6. ELECTRICAL CONNECTION
Unless the power is o, do not wiring
the junction box. The electric pump should
have reliable grounding to prevent current
leakage with leakage protection switch
being equipped.
6.1 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.
6.2 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.

6.3 In case the electric pump is used outdoor, extended lines
should apply rubber cables for outdoor use.
6.4 Check rotation of the motor (three-phase motor).
6.5 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.
5. START-UP AND MAINTENANCE
Do not start up the pump before the pump
chamber is lled with water.
Do not touch the electric pump unless its
power has been cut o for at least 5 minutes.
Do not dismount the pump body unless
water in the pump chamber is empted.
Rotate the fan blade before start-up, check whether the pump
rotation is flexible and then unscrew the water-filling plug, fill
the pump chamber with clean water from the water injection
hole, then tighten the plug screw after gas has been completely
discharged The valve should be shut tightly while starting up the
pump. After the pump discharges water and operates normally,
adjust the valve to the required flow (flow and lift will be
dsplayed on the nameplate).
ATTENTION:
1. 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.
2. 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.
3. 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.
4. In case the pump is halted for a long time, start it up again
according to above diagram.
5. In summer or when the ambient temperature is high, pay
attention to ventilation, avoid dew on electrical parts which will
result in electrical faults.
6. In case the motor is hot or abnormal, cut off the power
immediately and check faults according to the following table.
