3.3. Installing the unit
WARNING
Install the air conditioner in a location which can withstand a load of at least 5 times the
weight of the main unit and which will not amplify sound or vibration. If the installation
location is not strong enough, the indoor unit may fall and cause injuries.
If the job is done with the panel frame only, there is a risk that the unit will come loose.
Please take care.

(2) Setting the positions of hanging bolt and
ceiling opening.
• Use an installation template (packaging top
surface) to set the positions of the hanging bolt
and ceiling opening and drill holes.
(3) Hanging
structure.
• Select a strong structure for the hanging location.
• If necessary, reinforce the hanging bolt with quakeproof columnar support material to
prevent shaking.
• Use hanging bolts of M8 to M10.
3.3.2. Hanging preparations
• Firmly fasten the hanging bolts as shown
in the figure or by another method.
• Install the hanging bolts at a place
where they would be capable of holding
a weight of at least 490 N per bolt.
