K-437 Operation Manual, Version A
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.
NOTE
We recommend to operate the instrument under a ventilation hood.
ATTENTION
To ensure the instrument safety do not place any object on top of it.
ATTENTION
For safety reasons, make sure that the distance between the instrument and another object or the
instrument and a wall is at least 5 cm.
ATTENTION
If your are working with a Scrubber, place it on the left side of the K-437. The Scrubber ventilation is
located on the left side. In case the Digest System is placed on the left side, cool air will hit the dige-
stion sample and cool it down, so that no digestion can take place.
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 (Digest System K-437 and Scrubber).
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 Digest System K-437 to the mains with the power cord contained in the scope of
delivery. To start the Scrubber automatically at the same time the digestion process starts, connect it
to the Digest System K-437 with the optional connection cable.
