Before The Air Cell
If the F60 is installed before the air cell in the system it will only start the pump on
pressure since the initial draw off will be supplied from the air cell. The only
change in state the controller will see will be the falling pressure. Choose this
arrangement if you want to keep pump starts to a minimum and you are prepared
to accept the delay in starting associated with the slow pressure fall from the air
cell.
After The Air Cell
If you install the F60 in the pipework after the air cell the controller will start the
pump each time flow pushes its paddle forward or each time pressure falls to
whatever pressure you have set the controller to start at. Choose this arrangement
if you want the system to deliver a fairly steady pressure and to start each time
flow is sensed.
