Dispensing Systems - Miele PG 8504 Operating Instructions Manual

DOS priming
(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.
