10. For electric pumps not used with total lift (the upper and lower limits of lift are
specified), they must be used within the usable range of lift to avoid damage of electric
pumps due to overload. For electric pumps used with total lift, the pipe diameter adopted
shall be consistent with but not greater than the specified pipe diameter to avoid overload.
11. Electric pumps are of dry structure, and it's not allowed to fill the cavity of motor with
oil or water.
12. The oil chamber of the product is filled with No.10 white oil for food-level machinery
to ensure that mechanical seal is lubricated and cooled effectively, and leakage may occur
when the product is damaged or out of order. In such service environment as plantation,
cultivation, or delivery and processing of drinking water or food, leaking white oil may cause
damage to planted plants or farmed animals or pollute drinking water or food. The user
shall evaluate the service environment and the consequence of using the product prior to
selection and use of the product to confirm whether the product is applicable, and shall
invite related professionals for confirmation where necessary. In case of leakage of white
oil, the user shall immediately stop using the product and handle it properly.
13. When electric pump is running, if it is needed to adjust the position of electric pump
or touch the electric pump, the power must be disconnected first to avoid accidents.

14. When electric pump is running, it's strictly prohibited to immerse cable joints or plug
boards into the water; if this is needed for extension of cable, the joints shall be sealed and
covered strictly to avoid electric leakage due to water seepage. (Refer to the figure below)
1 . R e m o v e t h e
insulating layer without
damaging conductor
2 . S t a g g e r s e v e r a l
conductors in length
3. Ensure no oil, water
or other dirt at the joint
No less than 10 times of conductor diameter
1. Tighten up the joint by
dividing it into several
strands evenly (at least 6
strands).
2. Cross two joints by such
a length that the wire ends
reach the insulating layer at
both ends.
1. Tighten up the strands together, take out
one strand from the middle and twine it to
one end (the twined core wire contains the
other strands), and then twine other strands
one by one.
2. Repeat the step above at the other end.
3. Tighten the joint with pliers, and coat the
joint with tin to achieve the best effect.
Note: See the attached figure 1 and
attached figure 2 for other methods
