DOS venting
The dispensing system for liquid process chemicals can only
dispense reliably if the system has been purged of air.
The DOS system must only be vented:
– if the dispensing system is being used for the first time,
– if the process chemical container has been replaced,
– the dispensing system has been sucked completely dry.
Before venting, ensure that the liquid process chemical container is
sufficiently full and the suction lance are securely screwed to the
containers. Only one DOS system can be vented at a time.
Open the systems menu by switching the machine off with the
button and then switch it on again with the
button whilst keeping
the
button pressed in.
Open the menu as follows:
