2. In principle, if a crown wall (obstacles for keeping out the wind) exists over the machine, a
distance of at least 3000 mm should be left between the top of the machine and the crown wall. If the
front, rear, left and right sides of the machine are open spaces, the distance between the top of the
machine and the crown wall should be at least 1500 mm, as shown in Figure 7. If the requirement for the
minimum 1500 mm cannot be met, or the spaces around the machine are not open, an air return pipe
needs to be connected to maintain smooth ventilation, as shown in Figure 8.
Figure 7
Installation space requirement for multiple ODUs
To ensure smooth ventilation, the top of the unit must be open spaces without obstacles.
If the front and left (or right) sides of the ODU are open spaces, the units should be installed along
the same or reverse direction.
