(1)Although grease has been added to the bearing, there is no need to add grease before
operation, but just in case, please confirm it.
(2)Flush the pipeline before the pump is put into operation. At this time, a filter should be
installed on the suction side so that foreign matter (metal particles, sand, rust and
oxide scale from the pipeline, etc.) will not enter the pump. Failure to flush may result
in wear of mechanical seals and rotating parts.
(3)Rotate the water pump by hand to check whether it rotates smoothly. If the rotation is not
smooth, it indicates that there is rust in the pump, please check these matters.
(4)Be sure to fill the water before starting the pump. Running the pump without water
injection can cause a failure. Open the suction valve and the drain valve, and fill up
with the water in the piping to the water outlet of the pump.
(5)When injecting water, gently rotate the main shaft of the pump to completely discharge the
air in the impeller.

In the event of a malfunction, please cut off the power
immediately and have it repaired by your dealer or Ebara
Machinery (China) Co., Ltd. in order to avoid accidents caused
by misuse.
Keep people away from the suction port of the suction piping of
the pump to prevent hands and feet from being inhaled.
When conducting the motor insulation resistance test during
assembly, remove the wiring from the control cabinet, measure
the insulation resistance with an insulation resistance meter
that matches the power supply voltage, and confirm that the
resistance between the motor lead-in wire and the ground exceeds
1MΩ, and then install the wiring. . So as not to burn the
motor, resulting in electric shock and fire accidents.
Do not touch the motor to avoid hot burns.
Never turn on the power after draining the pipes in order to
avoid idling, causing damage to the water pump, overheating
damage.
Please operate the pump within the specifications. If it is used
in the case of variable flow, the operation with less than the
minimum water volume (equivalent to the suction diameter [mm] of
the pump, for example, if the diameter is 50mm, the minimum
water volume is 50L/min) should be avoided. In order to avoid
air lock in the pump, the internal pressure and temperature
rise, causing damage to the pump.
