WARNING
When removing the de-airing needle, never pull on the de-airing tube,

Before removing the de-airing needle, be sure that the de-airing tube is
secured to the de-airing needle. IMPORTANT: Once the de-airing
needle has been removed it cannot be re-inserted.
NOTICE
Do not remove the de-airing needle until all air is removed, the blood
pump is running, all parameters have been adjusted and the chest has
been closed. (see section 7.2.10: Checking the parameters when the
pump is started and adjusting them, page 103).
INSTRUCTION
1. Cut the suture material between the

nipple (see image 1 in Fig. 9-14,

ligature around the de-airing nipple
(see image 2 in Fig. 9-14,
