8. Place the O-ring screw over the inner needle so that the internal hexagonal hole is facing the inside of the
needle holder.
▪ The small hole in the O-ring screw should stay about 2 mm above the holder.
9. Place the spring QWVR012260 over the inner needle, insert the special O-ring screw spanner TLAX110026,
and tighten the O-ring screw slightly.
▪ Hold the needle assembly block tight and turn just the spring clockwise.
10. Insert the outer needle carefully into the needle tool TLAX110023, place the inner needle, without damaging
the inner needle tip, straight through the outer needle.
11. Hold the spanner TLAX110026 in one hand, and tighten (hand-tight) the outer needle by turning the needle
tool TLAX110023 clock-wise.
12. Remove the spanner TLAX110026, hold the needle assembly by the assembly block, and tighten the outer
needle firmly with TLAX110023.
13. Check if the pipes are facing the same direction.
14. Compress the needle assembly, it should move smoothly.
Check for leakage
1. Check the needle assembly for leakage by short-circuiting both ends of the outer needle with a short length of
tubing.
2. Connect a syringe with air to the inner needle and immerse it in water.
3. Pressurize it with the syringe - air bubbles should not be visible.
4. Dry all parts.
Needle assembly
1. Place the needle back on the instrument.
2. Fasten the knurled knob, do not fasten too tight
3. Connect both tubes to the needle.
4. Place drip tray.
Check/Clean liquid sensor
The Liquid sensor on the Processing unit has to be checked on regular base and cleaned if necessary.
