. To

make the connections, you must open the enclosure of the field device. To do this, unscrew the spring bolts

⑥

until you feel

the spring pressure. You can then remove the screws by hand.

4.5.2

Connecting flame arrestors

Installation of the flame arrestors
Sample gases which are occasionally explosive may only be connected to the Calomat 6F, Calomat 62F and Oxymat 6F

gas analyzers if the sample gas inlet and outlet are each provided with one flame arrestor with adapter.
You can find information on the installation of the flame arrestors in the section Connection of the flame arrestors (Page 11).
