Page 10: Pump Operation
When positioning the pump it is important to ensure adequate motor Ÿ cooling through water flow past the motor. It is recommended that the complete pump is submerged at least 3m below Ÿ the dynamic water level and if possible the pump should be installed at least 3m from the bottom of the borehole to prevent silting damage. -
Page 11: Maintenance
As the valve is being opened, the water output should be monitored to ensure Ÿ that the pump output does not exceed the borehole capacity as indicated by the pump starting and stopping on the low level relay (if fitted) or uneven water flow at the outlet. -
