Priming and Operation
Automatic Water Pressure System
1. Fill pump and suction line through the pump discharge or priming port (on ooded 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. There will be
a delay of less than 1 second before the pump starts.
4. Prime should establish almost immediately and a strong ow of water should be evident from
the outlet. Allow water to ow for 10-20 seconds to expel air then close outlet. Pump will
switch off shortly after and wait in standby until a drop in pressure initiates a pump start.
5. If no ow 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.
6. If the pump does not automatically restart on re-opening of tap, consult trouble shooting guide.
Automatic Pressure Controller
The unit is pre-set at a restarting pressure of 150kPa. The pump will stop at approximately 0.5lpm. If the pump reaches
above 230kPa at low ow stop, then it will go to standby. If the pressure has not risen at low ow the controller will detect
a fault.
Never operate your pump for more than several seconds without discharge ow.
NOTE: If the static discharge head (vertical height) above the pump exceeds 15m, the Automatic Pressure
Controller will not allow the pump to start. Consult your TotalFlo dealer for advice.
