E. Loosen the Furnace Head Z-Brackets holding the Furnace Head Assembly in
place and rotate them away from the top of the Furnace Head Assembly.

completely cool, set this hardware on an appropriate heat resistant surface.
Ensure this is somewhere safe.

hardware is now accessible. For more information, see “To Clean or Replace the

Injection Needle
To Clean or Replace the Injection Needle
1. Prepare the Analyzer for extended maintenance. For more information, see “Quick
Maintenance Procedures” on page 185.
2. Perform the procedure, “Accessing the Furnace Head Assembly” on page 200 until
Step 8 on page 202
and return to this procedure.
3. Ensure the Furnace Head Assembly and Injection Needle are removed from the
Analyzer.
4. Important! If not already cooled down, allow the Injection Needle [15] and
Furnace Head Cover [6] to cool completely before pulling the Injection Needle
[15] out of the Furnace Head Cover [6]. This is an important step as pulling the
Injection Needle out before cooling will damage the fittings and ferrules that hold the
needle tightly in the Furnace Head Cover. See Figure 6-9 on page 203
.
5. Once cooled, remove the Injection Needle [15] from the Furnace Head Cover [6].
Loosen the Furnace Head Compression Nut [10A] and pull the Injection Needle [15]
out of the Furnace Head Cover [6]. Re-tighten the Compression Nut [10A] to be
finger-tight. Do not remove this fitting! Important! Do not lose any nuts or
ferrules! See Figure 6-9 on page 203
.
6. Inspect the Injection Needle for corrosion and restrictions. If any corrosion exists it will
be on the Furnace end of the Injection Needle.
7. Clean the Injection Needle. Replace the Injection Needle if unable to clean effectively.
• Rinse with DI water.
• Use a wire slightly smaller than the ID of the Injection Needle to clear the inside
from debris.
