How often should I run the self-cleaning function?

It is recommended to operate the self-cleaning function once every 3 months. The function runs for 30-50 minutes and helps carry away accumulated dirt and bacteria from the indoor evaporator. It is best to run this when the indoor ambient temperature is under 86°F / 30°C and outdoor temperature is between 41°F - 86°F / 5°C - 30°C.
