7-2. Multiple unit installation
・When installing multiple units, make sure to take into consideration factors such as providing enough space for
people to pass through, ample space between blocks of units, and sufficient space for airflow. (The areas marked
with Ⓐ in the figures below must be left open.)
・In the same way as with the single unit installation, add the dimension that exceeds the height limit (shown as "h1"
through "h3" in the figures) to L1, L2, and L3 as shown in the tables below.
・If there are walls in the front and rear of the block of units, up to three units can be installed consecutively side by
side, and a space of 1000 mm (39-3/8 in) or more must be left between each block of three units.
