 Briefly reconnect the mains power supply to the pump – the ‘power on’ light should
illuminate if the pump has been correctly wired.
 Isolate the mains electrical power supply from the pump.
 Re fit the terminal box lid ensuring no cables are trapped.
 Re fit the four terminal box lid retaining screws, tighten to 0.8 Nm.
Flow Switch Circuit Test
1. First confirm visually that the flow switch reed clamp have not been dislodged during
handling or installation. The clamp must be fully located within the flow switch body
groove as shown.
2. To carry out the following test you will need to obtain
a magnet, a typical fridge magnet is suitable.
3. Ensure the power supply is switched on.
4. Position the magnet directly in front of the reed
clamp as shown. If pump does not start, then
slowly move the magnet up and down to a
position that exceeds the extent of the reed
clamp. The pump should instantaneously start
at some point during this extent of movement.
If this does not happen, this indicates a possible
fault with the reed switch or the P.C.B which is
located within the terminal box. These should be
checked electrically. Consult Stuart Turner for further instructions.
