- Before diving the pump into the water, turn on the power for test run, but it should not exceed 3s. The cable of the single-phase pump should be strictly as
per the wiring diagram as indicated on the motor or the control box, and should be wired by the corresponding colours. Incorrect wiring will cause the pump
to work abnormally and may damage he motor; the three-phase pump can be wired despite the colours, when the pump rotates in the reversed direction(-
from the end of motor shaft, the correct direction is indicated if the motor rotates counter-clockwise), just change the connection of any two lines.
Warning! Electrical connections can only be performed by electrical professionals, and please comply with state regulations.

- Prior to purchasing and installation of the pump, check if the inner diameter of the well matches the min-
imum diameter of the well pump. For a new well, remove debris and dirt with an air compressor or an old
well pump, then check if the water quality and temperature matches the conditions for well pump. Install the
well pump only when the water in well reaches the standard of pump for use.
- To install the electric pump in pond, hoist it with a tripod or assisted by boat, bridge or wharf, do not place
it directly at the river bottom, otherwise the motor may gradually get stuck in the mud to cause blockage, get
too high temperature, and burn out the motor.
- The submersing depth of electric pump is appropriately as 0.5-5m below the dynamic water level, if too
shallow, the pumping quality will be poor due to reduced water level, even cause motor failure due to run-
ning without water.
- The electric pump must be used at an appropriate voltage. If the power supply is far from the place where
the electric pump is used, the extended cables should be appropriately thickened according to the distance,
the connectors should be sealed and bound with waterproof insulation tape, so as to make sure it insulated
and off the ground. If necessary, ask a professional electrician to test if the operating voltage of the pump is
within ±10% of the rated voltage, so as to avoid under-voltage operation because the cable is too long and
the voltage drop is too great, which may cause burnout.
