Ÿ To prime pump, add water to the priming plug until it overflows.
Ÿ When installing the water pump, avoid use of soft rubber pipe, due to risk of
collapsing.
Ÿ The foot valve shall be vertical and installed 30cm away from the bottom of the water
to avoid drawing in of sediments.
Ÿ All connections of the inlet pipeline must be sealed to minimize elbows, otherwise
suction may not be effected.
Ÿ The diameter of the water inlet pipe shall be at least the same as that of the pump inlet
to prevent hydraulic loss from affecting the water outlet performance.
Ÿ When using the pump pay attention to the water level drop and ensure the foot valve is
not exposed above the water surface.
Ÿ When the length of the water inlet pipe is more than 10m or the lifting height of the
water is more than 4m, the diameter of the water inlet pipe must be greater than the
diameter of the pump inlet.
Ÿ When installing the pipeline, make sure that the pump is not under pipeline pressure.
Ÿ It is advisable to install a strainer when source water is suspected to be dirty.
Ÿ The outlet pipe diameter shall be at least the same as the outlet diameter to minimize
the pressure drop, high flow rate and noise.
Ÿ When the water pump is installed in a place that may be flooded ensure to install a
raised platform to prevent the ventilation holes from being flooded.
Ÿ When installing the pump, ensure to eliminate any air locked within the pipeline.
