Instructions
The fans are suitable for more demanding applications (professional kitchens, industry) due to their higher operating temperature (120 °C) and performance characteristics. If the fan is operated in heat and smoke extraction mode, speed control is not permitted and safety protections such as thermocontacts must be disabled.
Warning
Fans are supplied without flanges, motor cover, frame and silent blocks fitted. These elements must be ordered separately (see accessories).
