After switching off the ventilator, the damper closes automatically.
The air damper opening and closing process can take up to five minutes.
Caution! If the power supply is cut off during operation of the ventilator, after five minutes, the damper can be manually
moved to the CLOSED position using the handle to prevent drafts.
Later on, when the ventilator is turned on, the damper will automatically open.
