If the drive was already connected to the cooling system and you want to store the drive again,
empty the drive completely prior to storing it. To empty the drive proceed as follows:
1. Open the connection between the cabinet piping and the external piping.
2. Drain the coolant.
3. Then tighten the screws again.
4. At one of the flanges of the cabinet piping, connect oil-free compressed air or a nitrogen
bottle. Use a suitable transition element. Blow out any residual water.
NOTICE
Damage caused by excessively high blow-out pressure
If the blow-out pressure used exceeds 6 bar, the piping and the heat sink can become
damaged.
● Do not exceed the blowout pressure of 6 bar. Avoid pressure surges.
