Installation of more than four units (Horizontal connection)
Forced air-cooling is needed.
To use four units, place partitions (heat resistant) between adjoining units, as illustrated below. Then, forcedly
ventilate from under the units with the fans.
If ventilation from under the units is impossible, always check the temperature at the back of the units and
forcedly ventilate in the direction of the flowing air with a fan. In that case, do not use partitions.
