• 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.
• Make sure that the user cannot access the unit main body after the installation.
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 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.)
Secure the space required to installation and servicing.
