To open the multimode source

Open the multimode source to access the end cap and the capillary cap for
cleaning and inspection.
Do not touch the multimode source or the capillary cap. They may be very hot. Let the
WA R N I N G
parts cool before you handle them.
Never touch the source surfaces, especially when you analyze toxic substances or
WA R N I N G
when you use toxic solvents. The source has several sharp pieces which can pierce
your skin including the APCI corona needle, vaporizer sensor and counter current
electrode.
Do not insert fingers or tools through the openings on the multimode chamber. When
WA R N I N G
in use, the capillary and capillary cap are at high voltages up to 4 kV.
1 Turn off the multimode source temperatures and flows:
2 Open the spray chamber cover by pulling the latch.
3 Check that the vaporizer temperature sensor is straight and extends 15mm
4 Check that the separator is aligned vertically.
5 Check that the APCI corona needle is in and extends approximately 3mm
6 Check that the source is clean.
