The previous owner recieved the codes as they are entered. So, just like stated above. including / and +.
They are always 22 digits. 

Big note: There is NO internet connection on the machine. everything happens local.
if there is an update, you will recieve it by CD-ROM. Well, not anymore..

The only thing you enter, is the 22-digits hash. No need to tell the machine the type or amount of treatments.
Previous owner told me that if he ordered 20 disposable parts, there would a 20-digit license key included.
All data is included in the hash.

I'm not sure about this. i just have this feeling. 
On the other hand i think there is some kind of private key in the machine.

Finding firmware upgrades and decompiling that or gaining access to the device through debug ports (JTAG for example) would allow you to more precisely determine how this system works.
I am currently making an clone of the disk. After that i'm gonna try to decompile / reverse engineer / try to bypass the check. Will keep you updated. Might need some additional assistance later.
