4 Remove the air needle.
5 Tighten the height adjustment nut on the fixing nut (made of
chrome). The thread of the height adjustment nut must match the
lower part of the fixing nut. The O-ring must be properly seated in
the fixing nut.
6 Insert the air needle.
7 Mount the sample needle.
8 Set the correct needle height for the new needle in the manual con-
trol feature of MagIC Net on the Needle tab.
NOTICE
If you are using the sample racks with 12 or 48 vials, then you
must adjust the setting of the needle height to > 2 mm. This will
prevent the needle from touching the bottom of the vial.
