•
Aerate the rotor chamber
completely
Lid contacts error
•
The system has detected an
open lid during the evaporation.
The rotor will be stopped
immediately. The lid must be
closed while the rotor is moving.
•
Check the lid contacts. If
necessary, contact the after-
sales service (see chapter 7.2 -
"Service contact")
Rotor overtemperature
•
The maximum permissible rotor

– glass breakage during the
evaporation
– uneven evaporation
•
Eliminate the imbalance and
restart the unit. If the error is still
present, contact the after sales-
service (see chapter 7.2 -
"Service contact")
