It has a water connection for water and ice. Both a hose for this and a 3/4" to 1/4" adapter are included. You then only need a "splitter" for your fixed water connection so that the fridge has its own 1/4" connection.
I bought the "Smardy Blue connection set" from Brack (also available as "Smardy ZO004 Universal connection set" on Digitec) so that I could prepare everything before delivery. The 3/8" adapter from the connection set fits much better to my existing water connection setup.
