The following steps are to be carried out before initial commissioning:
• Plug the cold-device connector of the supplied mains connection cable into the cold-device socket
for gas conditioning;
• Connect power cord to the network;
• Switch on power supply.
After the end of the lead time, the gas conditioning unit is ready for operation (green LED on the
controller lights up).

In the case of long-term measurements with high dust content in the
sample gas, a suitable gas sampling probe to protect the sample line
from clogging must be provided.
