DOS priming
The dispensing system for liquid process chemicals can only dis-
pense reliably if the system has been purged of air.
The DOS system must be primed only if:
- It is being used for the first time.
- The reservoir was exchanged.
- The dispensing system has been emptied completely.
Before priming, ensure that the liquid process chemical container is
sufficiently full and the siphons are securely screwed to the contain-
ers. Only one DOS system can be primed at a time.
Open the menu as follows:
