It is possible to expand the 'Diner4All' set with a 'Diner4All 2 Persons' set (Fig 3).
Therefore you have to disconnect one plate of the 'Diner4All' set and plugin the main plug of the 'Diner4All 2 Persons' in the free socket (Fig 1).
You can then plugin the two plates of the Diner4All 2 Persons' set in the socket together with the left over plug of the Diner4All set (Fig 2).
