7.1.2.2 Aeration and media drain valve
A malfunction of the aeration and media drain valve may have several
causes. One potential source are contaminants such as product residues
within the valve.
• Switch the freeze-dryer off and disconnect the mains plug.
• Clean the valve (see chapter 8.1.1.3 - "Aeration valve, media drain
valve").
• Put the freeze-dryer into operation again.
If there is still a leakage, the freeze-dryer must be checked by qualified
specialist personnel (see chapter 7.3 - "Service contact").
