DAB Submersible Pump Installation Instructions 2013 rev 1

 

 

3

 

 

TYPICAL SUBMERSIBLE INSTALLATION

 

 

Pump connected for 

 

 

Submersible water pressure system 

manual operation  

 

incorporating 100 litre pressure tank 

 

 

DEPTH OF INSTALLATION 

Make sure that the unit is at least one metre above any gravel layer and one metre below the minimum 

drawdown level. If during the initial operation, the pump lowers the well water level until suction is 
discontinued, then lower the pump where feasible, or install a protection device, or reduce the flow rate of the 
pump to prevent over-pumping.
