NOTE
Check all connections of the system for leakage at regular intervals and
particularly after having made any modifications.
WARNING
The gas system is under pressure. It contains both pressurized gases
and liquefied gases.
Before the sample vessel can be changed, the pressure must be
released in the piping system and the latter may need to be rinsed with
nitrogen.
Observe the applicable regulations.
WARNING
The oven used for vaporizing the liquefied gases and the oil filter down-
stream of the oven may exhibit a temperature of up to 70 °C. Avoid
direct skin contact. Wear heat-insulating gloves, if necessary.
Clean the oil filter and rinse the piping carrying gas through the oven
only with the instrument switched off and while it is cold.
