Electronics are constructed with solid-state components and epoxy-potted. Periodically, check and clean the sensor when used with liquids which cause a coating build-up on the sensor. No other maintenance is required.

If the pipe or vessel to which the unit is mounted is to be steam-cleaned or cleaned with abrasive detergents, remove the entire unit before cleaning by:

  1. Disconnecting the power at source
  2. Opening the housing cover
  3. Removing power and control wiring cables
  4. Unthreading the sensor

To reinstall, follow installation procedures.
