• Replacing the active carbon filters on the carrier gas line and split line
The active carbon filters must be replaced depending on the volume of solvent injected in
the time.
See "Replacing the Carrier and Split Lines Filters"
• Replacing the body head O-rings
The internal (carrier line) and external (purge line) O-rings of the body head must be
replaced when there are leaks present.
See "Replacing the Body Head O-rings"
Before maintaining the injector, read the following warning:
WARNING The injector fittings could be hot. Carry out all the operation at low
temperature to avoid burns. Therefore, before beginning the sequence, the injector must
be cooled to room temperature.
CAUTION When handling organic solvents, you must take precautions to avoid health
hazards.
ATTENTION Pendant la manipulation de solvants organiques, prenez les mesures
nécessaires pour éviter tout risque sanitaire.
