1. Cleaning in general
(1) If, during cleaning, the remote control is used to start the
air-conditioner by cooling, heating, or other operation,
the cleaning will be stopped at that time. While the product
is being run, the cleaner will be returned to its initial position.
(2) The cumulative count of operating hours will be initialized
only when the cleaning has come to a normal end.
2. Automatic cleaning

stopped, it will start to clean itself after that operation is over.
3. Manual cleaning
(1) Pressing the "manual cleaning" key while the air-conditioner
is running will not work.
(2) This will not be activated while the sleep one-more timer is on.
(3) This will not be activated during initialization or automatic
cleaning.
(4) Pressing the MANUAL CLEANING key during manual
cleaning will abort the cleaning.
