Warning:
Risk of injury!
If the device is switched on during assembly of the evaporating flask,
it is possible for the device to start rotation due to unintentionally
touching of the control panel; this could result in injuries.
Assemble and remove the evaporating flask only when the device is
switched off.
Warning:
Risk of glass breakage!
If one of the flasks is damaged, glass may break, and you may be
seriously injured.
Only work with glass which has no defects. Inspect the glass regularly
for damage.
