Installation of indoor unit

Work procedure
1. Cut an installation opening in the ceiling to the measurements specified for ceiling

opening.

2. Set the suspension bolts in place.

※

The suspension bolts pitch center do not match the panel center.

3. Make sure to use four suspension bolts and fix them so as to be able to hold 500N load.

4. Ensure that the lower end of the suspension bolt should be 50mm above the ceiling

plane. Temporarily put the four lower nuts 150mm above the ceiling plane and the upper

nuts on distant place from the lower nuts in order not to obstruct hanging the indoor unit

or adjust the indoor unit position, and then hang the indoor unit.

5. Adjust the indoor unit position after hanging it by inserting the level gauge attached on

the package into the air supply port and checking if the gap between the ceiling plane

and the indoor unit is appropriate. In order to adjust the indoor unit position, adjust the

lower nuts while the upper nuts are put on distant place. Confirm there is no backlash

between the hanger plate for suspension bolt and the lower nut and washer.
