7 Injector
1. Unfasten the knurled nut (Fig. 8, item 4) by turning it
counter-clockwise.
2. Slide the injection chamber as far as it will go over
the nozzle of the CRI/CRIN, CRI Piezo or DHK/UI.
3. Attach the injection chamber to the component by
turning the knurled nut clockwise.
i
Do not fasten the knurled nut so tightly that it makes
contact with the body of the injection chamber, as
thermal expansion of the hot injection chamber then
makes it difficult to unfasten the knurled nut.
4. Fix the injection chamber in position by means of
the injection chamber holder (Fig. 3, item 5).
