SELECTION OF INSTALLATION PLACE
WARNING
• Install the air conditioner at enough strong place
to withstand the weight of the unit.
If the strength is not enough, the unit may fall down
resulting in injury.
• Install the air conditioner at a height 8’ (2.4 m) or
more from the floor.
If you insert your hands or others directly into the unit
while the air conditioner operates, it is dangerous
because you may contact with revolving fan or active

subject to a risk of exposure to a combustible gas.
If a combustible gas leaks and stays around the unit,
a fire may occur.
Upon approval of the customer, install the air
conditioner in a place that satisfies the
following conditions.
• Place where the unit can be installed horizontally.
• Place where a sufficient servicing space can be
ensured for safety maintenance and check.
• Place where drained water will not cause any
problem.
Avoid installing in the following places.
• Place exposed to air with high salt content (seaside
area), or place exposed to large quantities of sulfide
gas (hot spring).
(Should the unit be used in these places, special
protective measures are needed.)
• Place exposed to oil, vapor, oil smoke or corrosive
gas.
• Place where organic solvent is used nearby.
• Place close to a machine generating high frequency.
• Place where the discharged air blows directly into
the window of the neighbor house. (Outdoor unit)
