2.4 Outdoor unit installation
1) Installing outdoor unit
When installing the outdoor unit, refer to "Precautions for
selecting the location" .
Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after

Fix the unit securely by means of the foundation bolts.
(Prepare 4 sets of M8 or M10 foundation bolts, nuts and
washers each which are available on the market.)
