2.4. VENTILATION SETTING / MONITORING
The performance of the fan is sufficient to achieve an air exchange rate of at least 10 times for the cabinet
models listed under point 1.3. The proper ventilation function is independently controlled by an electronic
monitoring system. The air volumes are monitored in the exhaust air shaft by means of pressure differential
measurement. An optical and acoustic alarm is triggered when the air exchange rate falls below the set value.
The visual alarm only goes out when the setpoint is reached again, the acoustic alarm can be cancelled by
pressing the “OK button” be interrupted.
