5 .3 .1 SpeedDigester connection
After the installation procedure has been completed successfully, the power plug of the SpeedDigester
must be connected to the mains for the digestion process.
Notice
Risk of instrument damage by wrong mains supply.
External mains supply must meet the voltage given on the type plate •
Check for proper grounding •
The used mains circuit has to:
provide the voltage that is given on the type plate of the instrument. •
be able to handle the load of the connected instruments. •
be equipped with adequat fusage and electrical safety measures, in particular proper earthing. •
See also technical data of all components regarding the different minimum system requirements!
Note
Additional electrical safety measures such as residual current breakers may be necessary to meet
local laws and regulations! External connections and extension lines must be provided with an
earthed conductor lead (3-pole couplings, cord or plug equipment). All used power cords shall be
equipped with moulded plugs only to avoid risks due to unobservant defective wiring.
5 .3 .2 Scrubber/water jet pump connection
To start the Scrubber B-414 automatically when the digestion process starts, directly connect it to the
SpeedDigester K-439 with the optional connection cable (Art. No. 14738).
Make sure that the voltage of the Scrubber B-414 corresponds to the voltage of the K-439.

To connect a Scrubber/water jet pump the plastic adapter piece must be installed to the suction
module and the hose connector must be mounted at the EPDM hose of the suction module 1 (see
section 6.7.3).
Now connect the EPDM hose coming from the T-piece 2 to the Scrubber B-414 or the water jet
pump to exhaust the digestion fumes (for a more detailed description see the corresponding instruc-
tion manuals of these devices). Make sure that the hose connection is as short as possible.
