The internal deionized water circuit
The internal water circuit is filled with deionized water (deionized, fully-desalinated water). The
conductivity of the cooling water must be ≤ 1 µS/cm in operation.
NOTICE
Inadmissible additives in the deionized water
Inadmissible additives in the deionized water can cause the cooling system to fail. This could
damage the drive.
● Use only deionized water that corresponds to the specifications. The specification of the
deionized water can be found in the documentation for the re-cooling unit.
