2. I then removed the draining screw and I drained the tubes in to a plastic

Draining the glycol from the tube
The glycol chamber contains about 0.6 liters of glycol and I highly recommend
changing the glycol, the picture below shows why you have to change it.

New (clear) glycol vs. old (discoloured) glycol
To get all the old glycol out of the chamber I recommend that you fill the
chamber 1/4 with glycol cleaning fluid or distilled water and shake it a few
times and drain it and do the same one more time then it should be clean.
