5.3 Loading the appliance

Warning!
When loading the appliance with an unsuitable load, poisonous
or explosive vapours or gases may be produced. This could cause
the appliance to explode, and persons could be severely injured or
poisoned. The appliance may only be loaded with materials which do
not form any toxic or explosive vapours when heated up and cannot
ignite (see also "Intended use" on page 8). If there is any doubt as to
the composition of materials, they must not be loaded into the appli-
ance.
Caution:
Check the chamber load for chemical compatibility with the materials of the appliance
(see page 11).
Insert the sliding steel grids or sliding shelves. The maximum number or grids / shelves and the
load capacity are specified in the technical data overview from page 14.
The chamber must not be
loaded too tightly, so that
proper air circulation in the
working chamber is guaran-
teed. Do not place any
chamber load on the floor,
touching the side walls or
right below the ceiling of the
working chamber (Fig. 13 , see
also the "correct loading"
sticker on the appliance).
In case of improper loading
(chamber loaded too tightly),
reaching the set temperature
may take longer than normal.

5.4 Operating the appliance

5.4.1 ControlCOCKPIT

In manual operation, the desired parameters are entered at the ControlCOCKPIT on the front
of the appliance (Fig. 14 and Fig. 15 ). You can also make basic settings here (menu). Addi-
tionally, warning messages are displayed, e.g. if the temperature is exceeded. In programme
mode, the parameters defined, the programme description, the programme segment cur-
rently active and programme duration remaining are displayed (for a more detailed descrip-
tion, see page 27).
