Inspect the instrument for damages during unpacking. If necessary, prepare a status report immedi-
ately to inform the postal company, railway company or transportation company.
Keep the original packaging for future transportation.
5 .1
Installation site
Place the instrument on a stable, horizontal plane and consider the maximum product dimensions.
Perform the distillations under vacuum with the Rotavapor placed under a fume hood. If this is not
possible due to shortage of space, mount the protective shield (optional accessory) and lead the
exhaust gas from the pump into the fume hood.
5 .2
Electrical connections
ATTENTION
Make sure that the voltage on the socket corresponds to the voltage given on the type plate of the
instrument.
Always connect the instrument to an earthed socket. External connections and extension cables
must be provided with an earthed conductor lead (3-pole couplings, cable or plug equipment) as the
mains lead has a molded plug, thus avoiding risks due to inadvertent defective wiring.
Make sure that no electric sparks form in the instrument or its surroundings as they might damage
the instrument.
5 .3
Commissioning the heating bath
Place the bath on the base plate of the Rotavapor.

it up slightly at the right-hand side and pull or
push it to the desired position.
