Remove injection lines (21/6)

When slackening and tightening the union nut, counterhold at threaded connection with wrench.
On no account exceed the tightening torque in order to avoid also slackening the threaded connection the next time.

Do not pinch or bend injection lines.
After detaching the injection lines, seal connections at the injection lines. Ensure scrupulous cleanliness!
