Translation of the original operating manual
9 Switch the vacuum pump off and aerate the drying chamber via the
media drain valve or via a rubber valve.
10 Switch the unit off by actuating the mains power switch and take the
product out of the freeze-dryer.
11 Switch the unit on again and start the defrosting process (button
"Operating mode: select/start" – "Defrosting").
CAUTION
Ensure that no water gets into the pipe connection of the vacuum pump or
vacuum sensor.
12 Drain the defrosting water via the defrosting water valve on the left-hand
side of the unit. To do so, connect a hose to the hose connector and
collect the defrosting water in a suitable vessel.
13 Keep the freeze-dryer open (i.e. without the lid or drying chamber) when
it is not in use so that moisture can evaporate. This increases the
service life of the vacuum sensor.
