MyVallox 149 Cfi is always delivered as a right-handed model (R). This means that the outdoor and exhaust air ducts, i.e., the ducts that lead outdoors from the apartment, are connected to the outlet collars located on the right-hand side at the top of the unit. The condensing water outlet is also located on the right-hand side at the bottom of the unit.
The handedness of the unit can be changed easily by interchanging the location of the front and the back doors.
