! CAUTION
• Do not install the indoor units in a ammable environment to avoid a
re or an explosion.
• Check to ensure that the ceiling slab is strong enough. If not strong
enough, the indoor unit may fall down on you.
• Do not install the indoor units in a machinery shop or kitchen where
vapor from oil or mist ows to the indoor units. The oil will deposit on
the heat exchanger, thereby reducing the indoor unit performance,
and may deform. In the worst case, the oil damages the plastic parts
of the indoor unit.
• To avoid any corrosive action to the heat exchangers, do not install
the indoor units in an acid or alkaline environment.
• When lifting or moving the indoor unit, use appropriate slings to avoid
damage and be careful not to damage the insulation material on units
surface.
4.3.1 Suspended unit
Install the indoor unit with a proper clearance around it paying
careful attention of installation direction for the piping, wiring and
maintenance working space.
Mount suspension bolts using M10 (W3/8) or greater are also
recommended, as size, as shown below:
