Operation

WARNING

• Only operate the ventilation unit if it is completely mounted and correctly installed, calibrated and set.
• 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. Close the shutters on PP 45 O units.
