1. Open the inlet grille, and remove the side cover fixing screw
(right and left) from the internal part of the unit.
2. Move the side cover to about 15mm forward to remove it.
Use the packing material (Styrene foam) to support, when
you reverse the top and bottom of the indoor unit.
3. Remove the hanging bracket
a. Remove the slip prevention screws of the brackets (right
and left).
b. Loosen the hanging bracket fastening bolts to about
10mm, and remove the hanging bracket.

•
Make sure the ventilation fan for smoke-collection hood on a cooking table has sufficient capacity so that it draws oily steam
which should not flow into the suction of the air conditioner.
•
•
•
•
Make enough distance from cooking room to install the air conditioner in such place where it may not suck in oily steam.
2. Avoid installing the air conditioner in such circumstances where cutting oil mist or iron powder exist especially in factories, etc.
3. Avoid places where inflammable gas can be generated, flows-in, contaminated, or leak.
4. Avoid places where sulphurous acid gas or corrosive gas can be generated.
5. Avoid places near high frequency generators.
