CAUTION
• The indoor and outdoor units and the power supply wiring and remote controller cord must be installed at
least 1m away from any televisions or radios. This is to prevent interference with picture and sound recep-
tion. (Interference may occur even at 1m away depending on the reception quality.)
• If installing the wireless kit, the distance of the signal sent from the remote controller might be shorter if
there are fluorescent lights which are electrically started (such as with inverters, rapid starters, etc.) in the
room. The indoor unit should be installed as far away from fluorescent lights as possible.
(2) Ceiling height
• Install this unit where the height of bottom panel is more than 2.5 m so that the user cannot easily touch.
(3) Air direction
The air direction shown is an example.
Select the appropriate number of directions according to the shape of the room and the location of the unit. (Field
settings have to be made using the remote controller and the outlet vents have to be shut off if two, three, or four
(corner shut-off) directions are selected. See the shut-off materials (sold separately) installation manual for details.)
(4) Use suspension bolts for installation. Check whether the ceiling is strong enough to support the
weight of the unit or not. If there is a risk, reinforce the ceiling before installing the unit.
(Installation pitch is marked on the paper pattern for installation. Refer to it to check for points requiring
reinforcing.)
