3.
Remove the protective stoppers from the requisite connections (process gases and waste gas
nozzle) on the back of the device.
4.
Attach the compressed air, the process gases, the mains cable, the waste gas hose and, if
necessary, the alarm plug to the designated connection points (see section
3.4.2
"Rear Controls
and Connections" on page 7).
5.
Regulate the pressure of the compressed air supply using the attached maintenance unit (see
section
3.4.2
"Controls and Connections on the Back" on page 7).
DANGER
The ashing device is operated with a 230 V AC supply. The electrical wiring work should
be carried out by a qualified electrician.
Have the electrician check that existing electrical installations are in good working order
and that fuses and cable cross sections are sufficient for the connection data on the
rating plate for the ashing device.
The exhaust gas hose must be fed
into an exhaust system
in order to discharge harmful
waste gases from the furnace chamber safely.
In order to continue the assembly process, you need to start the ashing device and open the furnace
chamber.
6.
Press the master switch on the front device (see section 3.4.1 Front controls on page 6)
7.
As the weighing pan is not in place, the unit cannot start properly. Wait until the error message
appears and confirm. Now, in the service mode, the hood may be opened. (Administrator
