How to properly store an unused KHD?

Hello,

Following the question above, what are the proper maintance steps that we should perform in case that we need to remove the KHD from our system for some time (6+ months).
I was thinking to:

1.Flush the measurment cell with RODI
2.Empty the measurement cell.

Would this be sufficient? Do we need to perform any more steps to ensure that no water is left inside the machine?

Thanks in advance.

Flushing the measurement cell and putting the pH sensor into it's original cap with some water should be enough.
