• Where there is much machine oil.
• Salty places such as the seaside.
• Where sulfide gas is generated such as a hot spring.
• Where oil is splashed or where the area is filled with oily smoke.(such as cooking areas and factories, in which the properties of plastic could be changed
and damaged)
• Where there is high-frequency or wireless equipment.
• Where the air from the outdoor unit air outlet is blocked.
• Where the operation sound or air from the outdoor unit does not bother the
house next door.
