If there is a power cut when the unit is operating, it will automatically resume the same operating mode when the power is
restored. (Applicable only to units with this feature).
Before turning off the power supply, set the remote controller's ON/OFF switch to the "OFF" position to prevent the
nuisance tripping of the unit.
If this is not done, the unit's fans will start turning automatically when power resumes, posing a hazard to service
personnel or the user.
