  • Page 9: Compressor Replacement

    Compressor replacement (Photograph page3) Ensure the component assembly backplate is completely isolated from the mains supply. The compressor operates on 230 volts ac and, therefore, it is essential the backplate is disconnected from the power source. Remove the pressure feed pipe from the red outlet on the compressor to the valve/manifold assembly.

Components it is necessary to reconnect the mains end cap to the logo! Power supply unit whilst the assembly backplate is out of the case.

  • Page 11: Replacing The Pressure Sensor

    Replacing the pressure sensor Locate the pressure sensor on the left hand side of the component assembly backplate (see drawing009 or 010). Remove the silicon pressure feed pipe from the sensor (see drawing 009). Using a pair of side cutters snip the two zip ties to release the body of the pressure sensor.
  • Page 12 Logo! Expansion unit replacement Make a note of all connections to the expansion unit before commencing disconnection. Using a small terminal screwdriver remove the two power feed connections to L+ and M at the top of the unit. Below these terminals there is a small grey sliding connector which will be located to the left of the slot.
