Cleaning
Turn off the heated zone for the inlet and allow it to cool.
Remove septum retainer nut, septum, insert retainer nut, and inlet
insert; also remove the column. Using a suitable light source, illuminate
the inside of the inlet. If there is evidence of contamination or deposits,
the inlet should be cleaned.
Use a swab and an appropriate solvent to scrub interior walls until
deposits are removed. A suitable wire may be used to dislodge solid
particles carefully. Dry thoroughly with compressed, filtered, dry air or
N
before reassembling. Vent lines can be removed for cleaning or
replaced as necessary.
Compressed, dry air or N
may also be used to blow out any loose
contaminating particles.
To avoid possible eye injury, wear eye protection when using
compressed gas.
