• Fix unit tightly with bolts as shown below so that unit will not fall down
due to earthquake or gust.
• Use concrete or angle for foundation of unit.
• Vibration may be transmitted to the installation section and noise
and vibration may be generated from the floor and walls, depending
on the installation conditions. Therefore, provide ample

Down piping and down wiring precautions
When down piping and down wiring are performed, be sure that founda-
tion and base work does not block the base through holes. When down
piping is performed, make the foundation at least 100 mm high so that
the piping can pass under the bottom of the unit.

and earthquake.
Any installation deficiency may cause unit to fall down, result-
ing in a personal injury.
When building the foundation, give full attention to the floor strength,
drain water disposal <during operation, drain water flows out of the unit>,
and piping and wiring routes.
