Abrasive Materials
The pumping of abrasive materials will cause damage to the pump which will then not be covered by the guarantee.
Connection of Mains Scheme or Town Water Supply to either Suction or
Discharge of Pump
Most Water Supply Authorities have strict regulations regarding
direct connection of pumps to mains water supplies. In most
cases an isolating tank is required between mains supply and
pump. Davey also recommend this method. Directly applied
mains pressure can exceed pump operating pressure and
damage pump.
Davey Products Pty Ltd cannot accept
responsibility for loss or damage resulting from
incorrect or unauthorised installations.
Priming and Operation
1.
Fill pump and suction line through the pump discharge or priming port (on flooded suction, simply open
gate valve to pump).
2.
Ensure outlet nearest to pump is open.
3.
Ensure all valves in suction line are open and switch on pump at power outlet.
4.
Prime should establish almost immediately and a strong flow of water should be evident from
the outlet. Allow water to flow for 10-20 seconds to expel air then close outlet and switch off
pump.
5.
If no flow is evident from tap, switch off at power point and repeat from step 1 ensuring there is an
adequate supply of water available to the pump.
