mal display.
In Normal display the activated functions are indicated by an icon showing the number of the respective
function. If several functions are simultaneously active, the icon displays a combination of the correspon-
ding numbers, e.g.

11.2 Using the optional connection “GAS/AIR 2” for ventilation
Regularly the inert gas connection / ambient air inlet „GAS/AIR“ (4) is used for ventilation.
The “GAS/AIR 2” function serves to close the valve of the standard connection „GAS/AIR“ (4) and acti-
vate the valve of the optional connection “GAS/AIR 2” (5), which is then used for ventilation
This allows convenient switching when both connections are used differently (e.g., for inert gas and am-
bient air).
If you activate the “GAS/AIR 2” function on a chamber, which is NOT equipped with the optio-
nal inert gas connection / ambient air inlet “GAS/AIR 2” (5), ventilation is no longer possible!
