X-STREAM Non-Incendive
Exhaust may contain explosive or toxic gases!
Gas connections not made properly may cause explosions or death!
Take care that all external gas lines are connected as described and that
they are gastight to avoid leakages!
The unit must be installed in a clean and dry area protected from strong vibrations and frost.
The unit must not be exposed to direct sunlight and sources of heat. Admissable ambient
temperatures (see technical details) must be adhered to.
Gas inlets and outlets must not be interchanged.All gases must be supplied to the unit already
processed. When using this unit with corrosive sample gases, ensure that these gases do
not contain components harmful to the gas lines.
Admissable gas pressure for all gases is 1500 hPa.
Exhaust lines must be laid inclined downwards, depressurized, protected from frost and
according to applicable regulations.
If it is necessary to disconnect the gas lines, the unit's gas connectors must be sealed with
PVC caps to avoid polluting the internal gas lines with condensate, dust, etc.
To ensure electromagnetic compatibility (EMC), only shielded cables (supplied by us on re-
quest, or of equivalent standard) may be used. The customer must ensure that the shielding
is correctly fi tted. Shielding and terminal housing must be electrically connected; submin-D
plugs and sockets must be screwed to the unit.
