NOTE:
If several units are mounted above each other, the required free space equals C +
D (see the following figure).
The outlet air used for cooling by the lower unit must be directed away from the
air intake of the upper unit with a piece of metal plate mounted to the cabinet wall
between the drives as shown in the following figure.
When planning the air circulation inside cabinets, recirculation of the air must be
avoided.
