Drainage tube (N2090 only)
This refrigerator has the possibility to drain condensation directly to the outside. Then the end
user does not have to empty the drip tray via the inside of the refrigerator. For this, you can
extend with your own tube (external Ø 0.35in [9mm], inner Ø 0.20in [5mm]) coming out of the
refrigerator at the back, and guide this tube directly to the outside of the vehicle.
