Defrosting
Defrosting of the ice condenser is carried out at room temperature or with
warm water.
• At a maximum, the ice condenser chamber may be half filled with water.
• Ensure that no water gets into the pipe connection of the vacuum pump
and the vacuum sensor (behind the cover plate, see figure)

• Drain the condensate through the media drain valve at the left side of
the freeze-dryer by attaching a hose on the nozzle (included in the
scope of supply) and placing a vessel underneath.
In order to avoid damage, the condensate must be removed directly after
the completion of the defrosting process. Then, any residual water must be
removed from the ice condenser chamber by way of a cloth.
