Dos Venting - Miele PG 8504 Operating Instructions Manual

DOS venting

The dispensing system for liquid chemical agents 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 liquid cleaning agent container has been replaced,
- if the dispensing system has been sucked completely dry.
Before venting, ensure that the liquid chemical agent container is
sufficiently full and the siphons are securely screwed to the
containers. Only one DOS system can be vented at a time.
