Stacking support OD40 for ovens DKN/DVS/DX402

• The stacking units must belong to the same series (among 400 series or among 600 series).
• Do not stack 400 series on 600 series. If the upper 400 series is not fixed well, it is easy to topple.
• Stacking of old models is not recommended. Lower unit must be new model.
