Hey,

I am planning on changing the cold trap oring for the first time on my markes TD-100. Wondering if you of you might have done this before. For those who are familiar, this is not the oring connected the removable solenoid assembly. This is on the opposing side. i would says it seals the top of the trap, its closest to the weak sorbent bed. It appears the entire peltier must be removed or at least pulled back to access the oring. Just wondering if anyone can confirm this is true or any pointers to successful completion. This procedure seems to not be mentioned in the user manual.

thanks all!
Hello

It is tricky operation but it is all about practice.
All you need is:
- o-ring extraction tool (with sharp tip)
- o-ring insertion tool (with small ball at the end)
- new o-ring
- filter disks
And a lot of patience :)

Good luck

Regards
