9-4. SELECTION OF INSTALLATION PLACE
WARNING
• 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.
CAUTION
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 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.
• Where the ceiling height is more than 3 m.
• Where the floor/wall/ceiling structure is unable to support the weight of the unit.
9-5. INSTALLATION OF INDOOR UNIT
WARNING
• Install the air conditioner certainly at a place to sufficiently withstand the weight.
If the strength is insufficient, the unit may fall down resulting in human injury.
• Perform a specified installation work to guard against an earthquake.
An incomplete installation can cause accidents by the units falling and dropping.
Locate the unit so as to provide uniform circulation of chilled air.
Avoid locating the unit as shown in the bad-marked figures below:
If a good location is not possible, use a fan to circulate the air evenly throughout the room.
Good location
Evenly hot or cooled
Bad location
Shaded area well hot or cooled
Bad location
