Wait until the heat register and housing parts have cooled off, use protective gloves if necessary.
• Switch the ventilation unit off immediately if it is damaged, especially if you discover damage or faults that could endanger persons or property. Prevent further use until the unit has been completely repaired.
• In the event of a fire or chemical accident (smoke, vapours) in your environment, switch off the ventilation unit until the outside air is harmless again.
