9. VENTILATION
CAUTION
The fire protection valves near the supply and extraction air connections are safety and
maintenance-relevant components.
In order to check the correct operation or to replace a defective element, please ensure that flexible
connecting hoses or sliding pieces are used to connect to an extraction system in order to ensure simple
dismounting and re-mounting of the extraction air connection.
• All models can be connected to a technical exhaust system via the exhaust connector. Please see the respec-
tively applicable national regulations for the specified air recirculation rate, maximum pressure losses and
exhaust air ducts.
• If installed on an exhaust system, a check must be carried out to ensure proper connection to the system (e.g.
using a smoke tube)
Ventilation wheel for technical ventilation
• The ventilation wheel serves as an indicator for correct ventilation.
If the wheel turns, the necessary 10-fold air recirculation rate is exceeded.
CAUTION:
In general these models can be operated without technical ventilation. The direct environment of
the cabinet can be an explosive zone in this case. If the cabinet is to be operated without an exhaust
connection, the user must attach a marking to it.
10. FIRE • DISPOSAL
10.1. OPENING THE CABINET AFTER THE FIRE
CAUTION:
Depending upon the duration of the fire an ignitable vapour/air mixture may have formed; therefore remove
all sources of ignition within a 10 metre radius of the cabinet before opening it.
- use only spark-free tools
- open the cabinets with extreme caution
10.2. DISPOSAL
The models can be disposed of once they have been dismantled and the materials sorted.
