If you see a green dash on the display (see the image below), make sure that the tap unit of your Philips PerfectDraft is positioned correctly. First, put the tap unit onto the connection top of the keg of your Philips PerfectDraft by pushing it down firmly. If you snap the tap unit onto the keg correctly, it fits nicely between the two keg chimes.
Tip: If you can move the arm of the connection top freely up and down, the tap unit is placed properly on the keg.
