during transportation or storage, for example, whether any cable or terminal box is in a perfect
condition. In case of any damage, please have a specialized person making replacement or
repair.
2.Before the Electric Pump operates, please completely inspect the cold insulation resistance
of the Electric Pump, which shall be not less than 100MΩ, or otherwise the corresponding
measures shall be taken and operation shall not be allowed until the relevant requirements are
met.
3.During the wiring of a three-phase electric pump, please properly install an electrical
leakage protection device to the pump. For those pumps provided with control box, please make
connecting according to the diagram in the control box or related instruction manual.

1.Remove the insulating layer
without damaging the
conductor.
2.Stagger long and short wires.
3.Ensure that no oil, water or
any other pollutant exists at the
connection.
1.Divide each connector into
several strands evenly (no less
than 6 ones) and tighten them.
2.Cross the two connectors so
that the overlapping length will
make the two ends are aligned
with the insulating layer.
1.Clench each strand. First get one strand
from the middle and make it wind to one
end (the wound core wire shall include the
remaining strands) and then make each of
the remaining strands wind successively as
well.
2.Follow the same procedure at the other
end.
3.Use pliers to tighten the connectors. The
best effects can be achieved by wrapping
the connectors with tin.
4.Remark: For other methods, please refer
to the attached Drawing 1 and Drawing 2.
1.First use the black tape to tightly wrap the connector
area and make two layers; do not expose the copper wire
head. Please see the attached Drawing 3.
2.Then use the pressure sensitive tape (self-adhesive
tape) to make a three-layer wrapping, 10mm longer at the
two ends should be needed based on previous layer
wrapping. Do not do wrapping until the length of the tape
drawn out is twice the original length.
3.Finally apply the plastic insulating tape (yellow
transparent) to make the last layer wrapping.
1.Properly arrange the connectors of core wires
and make a four-layer wrapping by use of the
pressure sensitive tape with two ends wrapping
a length of 30mm on the cable sheath and
10mm longer at the two ends should be needed
based on previous layer wrapping
2.Then make a three-layer wrapping with the
plastic insulating tape with the next layer about
10mm longer than the first layer at the two ends.

A joint made by cold welding of
casing is also acceptable.
When the first layer of the black tape is
made, no copper wire shall be exposed or
the tape shall not be punctured.
4.A single-phase electric pump with integrated automatically-reset thermal protector, when
the thermal protector works, automatic reset will happen after the temperature of the motor
decreases to a certain value, In the event of frequent protection actions, please cut off the power
supply and find out the causes and then operate the Electric Pump until the relevant trouble is
cleared. For a three-phase electric pump with integrated power failure-reset thermal protector,
upon the protection action of the protector, please first cut off the power supply and turn on the
power supply again after 10 minutes, Electric Pump will operate normally. In the event of frequent
protection actions, please cut off the power supply and find out the causes and then use the
Electric Pump until the relevant trouble is cleared.

30m
5.Before putting the Electric Pump into water, please carry out a test running for no more
than 10 seconds and simultaneously check whether the rotational director of the pump shaft is the
same as that indicated by the indicating arrow in the nameplate.
6.Connect a delivery pipe (whose specifications are selected based on Table 1) matching
with the discharge chamber. For example, tighten a soft delivery pipe with the iron wire or a clamp
or reliably connect a steel-type delivery pipe with the screwed joint, and then tie a rope to the
delivery chamber for the purpose of lifting and placing.
7.Do not strike or press the cable or use it as a lifting rope. When the Electric Pump is
operating, do not arbitrarily pull the cable, so as to prevent the cable from being damaged and
causing any electric shock accident. Upon installation, bind the cable to the delivery pipe or take
other proper measures for protection, so as to avoid any tensile deformation due to the great
dead-weight of the cable.
8.When the Electric Pump is submerged in water, its depth shall not exceed 70m (20m for
QJD series) and shall be at least 3m away from water bottom and it shall not be caught in sludge.
Simultaneously keep the mesh enclosure or the impeller from being blocked by water plants or
sundries, for such blocking may result in the Electric Pump's failure to operate normally. During
operation, please frequently check the water level and make sure that there is enough water to
cover Electric Pump.
9.Please arrange a safety warning sign on the site where the Electric Pump is operating,
which reads “DANGER: ELECTRIC SHOCK RISK AND NO ENTRY FOR PEOPLE OR ANIMAL”,
so as to prevent any accident.
DANGER: ELECTRIC SHOCK

11.Oil-filled electric pump filled with No. 10 white food machinery oil so as to ensure that the
mechanical seal is effectively lubricated and cooled, which might leak in case of any damage or
fault of the Electric Pump. The leaked white oil might damage the botany planted or the animal
bred or pollute the drinking water or food involved in any application relating to planting, breeding,
or delivery or processing of drinking water or food. To select a product hereunder, the user shall
evaluate the relevant application and the consequence of the use of such a product so as to
confirm whether the product is suitable and even invite a related specialized person to do such
confirmation when necessary. In case of any leakage of white oil, please immediately stop using
and properly dealing with it.
12.When the Electric Pump is being used, please first cut off the power supply in case that
the Electric Pump is to be relocated or touched, so as to avoid any accident.
V. Maintenance
1.The matters needing attention prior to the disassembly of the motor for maintenance: First
wait until the motor is cool, then unscrew the oil filler bole, to release the high-pressure gas
generated inside due to burn-in, for the purpose of preventing the upper cover from jumping out to
hurt people.
2.Regularly inspect the insulation resistance between the motor bracket and the winding of
the Electric Pump, which shall be no less than 1MΩ when the operating temperature is nearly
achieved, or otherwise usage shall not be allowed until the corresponding measures are taken
and the relevant requirements are met.
3. After the 2500-hours normal usage of the Electric Pump, the Electric Pump shall be
maintained as per the steps below:
a) inspect various easy broken parts such as the mechanical seal, bearing, and impeller.
Please immediately replace in case there are damaged ones.
b) After the completion of inspection and repair, please do an air pressure test under the
pressure of 0.2MPa; to wait until 5 minutes, no leakage occurs.
