In OMI we are always developing new solutions to improve the performance and reliability of our units to ensure the best customer experience. For this reason, technical documentation is constantly updated to match the actual unit’s components and features. Since the serial number is the unique data that identifies the unit, it is the only one that can guarantee the exact correspondence between the content of the documents and the real configuration of the unit. Knowing the model, code or date of purchase of the unit does not accurately identify its configuration and can lead to errors in maintenance or settings.
