Note
All device-specific piping and wiring diagrams are enclosed with the device in accordance
with the order.
NOTICE
Shortening the preassembled gas lines between the housing and the mounting bracket will
void the explosion protection for the gas chromatograph.
CAUTION
Do not remove the adapters
 Filters are integrated in the connections for the sample stream and carrier gas.

The adapters at gas connections 3, 4, 5 and 8 contain a R60 filter (order no. C70211-
A1677-C56) pressed into the screwed gland, and must not be removed.
4.4.3 Sample lines
● Fit the sample preparation equipment as close as possible to the chromatograph so that
the connection lines are short.
● The sample line to the chromatograph must have a downward gradient.
NOTICE
Filter for microdiaphragm valves
The microdiaphragm valves have a shorter life if the sample contains particulates.
In such cases, a filter is required as part of the sample preparation equipment.
We recommend a filter with a degree of separation for a gaseous sample of 99.99% for
1.0 μm particles.
The sample preparation equipment from Siemens AG contains such filters.
