Avoid installing the air conditioner in the following places.
• Where there is much machine oil.
• Salty places such as the seaside.
• Where sulfi de gas is generated such as hot spring, sewage, waste water.
• Where oil is splashed or where the area is fi lled with oily smoke (such as cook-

and damaged).
• Where there is high-frequency or wireless equipment.
• Where the air from the outdoor unit air outlet is blocked.
