Inspecting the Insulation Block/ALIDUM Cable
Assembly
The insulation block/cable assembly must be inspected weekly and replaced every six
months. Examine the cable where it connects to the insulation block. If there is any residue,
liquid, or if the cable is cracked at this connection, replace the assembly.
NOTE: Instructions on how to replace the insulation block cable can be found in
Replacing
the Insulation Block/ALIDUM Cable Assembly
on page 82.
Checking the Fluid Path (Tubing)
Check that all the tubing is clean and free of crimps. Refer to
Replacing the Tubing
on
page 85 for procedures to change tubing.

4. Gently pull downward on the insulation block until the system tubing is approximately
1 inch below the Z-Rack.
5. While holding the needle, remove the system tubing.
6. Remove the needle from the bottom of the insulation block.
7. To reinstall the needle, refer to
Sampling Probe/Needle
on page 15.
NOTE: If the needle has been bent, it should be replaced.

When cleaning the square shaft pinion, ensure no alcohol enters the
Z-bearing or is wiped on the Y-axis guide rails.
CAUTION
Electrostatic discharge to the needle may damage the
ALIDUM detector.
