5 Putting into operation
This chapter describes how the instrument is installed and gives instructions on initial startup.
NOTE
Inspect the instrument for damages during unpacking. If necessary, prepare a status report immedia-
tely to inform the postal company, railway company or transportation company.
Remove the transportation lock at the bottom of the instrument.
Keep the original packaging for future transportation.
5 .1 Installation site
Install the instrument on a clean, flat and stable base.
ATTENTION
To ensure the instrument safety do not place any object on top of it. Provide a distance of at least
30 cm between the instrument and another object or the wall. There should be no containers, chemi-
cals or other devices located behind the instrument.
We recommend to operate the instrument under a ventilation hood. Do not place the Extraction Unit
under the same hood.
5 .2 Electrical connections
WARNING
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.
Connect the Hydrolysis Unit B-411/E-416 to the mains with the power cord contained in the scope of
delivery.
5 .3 Connecting the suction hose to the suction tube and the pump
The suction hose is connected to the hose connection (Ø 10 mm) on the suction tube. The fumes
which result from hydrolysis and the wash water resulting from filtering the sample are extracted with
the pump. The suction tube can be connected to a water jet pump or to a vacuum pump with an
intermediate vessel. In order to achieve efficient filtration, the used pump should have a good suction
power and should be resistant to the chemicals used.
