• a sliding door including a first door leaf, a second door leaf, and a pivoting mechanism pivotally mounting the first and second door leaves;
• a housing adapted to be installed into the building wall, the housing having a first door opening and a second door opening opposite the first door opening;
• wherein the sliding door is mounted in the housing and is displaceable along a displacement axis beyond the first and second door openings on both sides thereof;
• wherein the pivoting mechanism converts a displacement movement of the sliding door into a pivoting movement of the first and second door leaves whereby the first door leaf exposes the first door opening and the second door leaf exposes the second door opening in a first position of the sliding door, the sliding door in the first position being arranged completely in a portion of the housing next to the first and second door openings, and the first and second door leaves close the first and second door openings respectively in a second position of the sliding door, the first position being spaced from the second position along the displacement axis;
• and
• wherein when the pivoting mechanism is deactivated the sliding door is displaceable beyond the first and second door openings into a third position in which at least one component of the sliding door system is accessible from outside the housing via the first door opening and/or the second door opening, and/or in the third position the sliding door can be removed from the housing via the first door opening and/or the second door opening, the third position being spaced from the first position and from the second position along the displacement axis, wherein when the siding door is in the first position the first and second door leaves are arranged at least partially in a first housing portion of the housing located next to a side of the first and second door openings, when the sliding door is in the second position the first and second door leaves are arranged at least partially between the first and second door openings, and when the sliding door is in the third position the first and second door leaves are arranged at least partially in a second housing portion of the housing located next to another side of the first and second door openings opposite the first housing portion.
