32 Replacing the Neon Indicator Light
Note : The neon indicator light is only applicable to the mechanical versions of the pump. The
electronic version of the pump has two red indicators, a green indicator and a yellow indicator.
These are wired directly into the PCB and are replaced only by exchanging the complete PCB.
32.1 Disconnect the indicator lead from the terminal block (terminal 2) (Fig 14, Item 10).
32.2 Disconnect the indicator lead from the Micro switch (Fig 18, Item 10).
32.3 Release the screw (Fig 17, Item 20) attaching the neon mounting plate (Fig 17, Item 10) and
remove the neon (Fig 17, Item 30) and mounting plate assembly.
32.4 Note the orientation of the components, unclip the neon (Fig 17, Item 30) from the lens and
push the lens out of the mounting plate.
32.5 Replacement is the reverse procedure of the above. Ensure the correct orientation of
components. Connect the wires to the terminal block and the Micro switch in accordance with
the wiring diagram for the mechanical version of the pump unit (Chap. 4, Fig 25).
