Rotavapor
R-220 EX
2 Safety
The machine must never be rotated without the snap flange
coupling and evaporation flask being closed.
No distillation may be started unless the evaporating flask is
immersed in the bath. There is always the risk that the neck of
the flask might break off due to the great weight involved.
There is a risk of becoming scalded while changing evaporating
flasks. Wearing gloves prevents this.
Check the glass components regularly for possible damage,
spreading impact marks, or cracks.
Never interrupt the grounding conductor (protective conductor).
Otherwise there will be the risk of an electrical shock!
The operator bears responsibility for providing proper instruction
of his operating staff. To aid him in doing this, translations of
this Operating Manual are also available in several other lan-
guages. As an integral component of the rotary evaporator, this
Operating Manual must be readily available at all times to the
operating staff at the location where they are using the unit.
The operator must inform the manufacturer immediately of
any and all events relevant to safety that occur in his use of
this equipment.
2.7 Modifications
No modifications are permissible without consulting with and
obtaining the written approval of the manufacturer.
No glass assemblies other than those recommended by the
manufacturer may be used, nor may any glass components
be put together arbitrarily.
Only those components of the rotary evaporator intended
for fulfillment of its function may be installed in or removed
from the unit. This may be done either by hand, or with the
use of the tool supplied along with the unit. The removal of
safety devices or covers using some commercially available
tool is — other than for authorized commissioning personnel
— strict ly forbidden. Contact with parts that are electrically
live may result in fatal injury!
