WARNINGS
• Install the air conditioner where there is sufficient strength to withstand the weight of the unit.
If the strength is not sufficient, the unit may fall down resulting in injury.
• Install the air conditioner at a position keeping the height by 2.5m or more from the floor.
If you insert your hands or others directly into the unit during running of the air conditioner, it is dangerous
because you may contact with revolving fan or active electricity.
CAUTION
• Do not install the air conditioner in a location subject to a risk of exposure to combustible gas.
Otherwise, the combustible gas leaks, stays around the unit and 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 safe 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 neighboring house. (For outdoor unit)
• Place where noise of the outdoor unit is easy to transmit.
(When installing the air conditioner on the boundary with the neighbor, pay due attention to the level of noise.)
• Place with poor ventilation. (Before air ducting work, check whether value of air volume, static pressure and
duct resistance are correct.)
