• When multiple units are installed adjacent to each other, secure enough
space to allow for air circulation and walkway between groups of units as
shown in the fi gures on page 2.
• At least two sides must be left open.
• As with the single installation, add the height that exceeds the height limit
<h> to the fi gures that are marked with an asterisk.
• Place protective padding at the corners of the product to protect the product
from scratches or dents that might be caused by the rope.

• Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a
personal injury.
• Have installation work in order to protect against strong winds and
earthquakes.
Any installation defi ciency may cause unit to fall down, resulting in a
personal injury.
When building the foundation, give full attention to the fl oor strength, drain water

When routing the pipes and wires below the unit, be sure that the foundation and
base work do not block the base through-holes. Also make sure the foundation
