4.3 Copying Heating
Programmes
Copying an existing heating programme allows you to
quickly and easily create new, similar heating pro-
grammes.
To do this:
1. Press the "P" key:
2. Select the heating programme you wish to use as
a template:
3. Select the "Copy heating programme" mode:
(press the ENTER key approx.
2 sec.) until:
- The programme LED;
- The programme number display flashes.
4. Select a new heating programme:
5. Transfer the values from the template to the new
heating programme:
While you are selecting a new programme
number in step 4, the LEDs of those heating
phases for which values have been pro-
grammed go on for every selected pro-
gramme. This makes it easy to find "empty"
or unused programme numbers.

If you press the ESC or P key during step 5 no val-
ues will be saved under the new number.

5. Operating the Oven

• Place the ceramic slab (B, Fig. 5) into the furnace
with the arrows pointing towards the rear wall and
push the slab fully to the rear.
Always use the ceramic pad when operat-
ing the oven!
Contamination of the heating muffle by wax,
cinders or soot can result in damage to the
heating muffle.
• Place the material to be heated in the oven.
Do not stack casting moulds!
Do not allow material being heated to be
in contact with the temperature probe
(A, Figure 5) as this will result in an
incorrect temperature reading.
• Close the furnace door.
The furnace door is mounted on floating
bearings to ensure complete and secure
closure and thus provide the best possible
temperature distribution in the furnace's
interior.
Therefore, when closing the door, its bot-
tom edge contacts the furnace opening
first, followed by the remaining door border.
In turn this results in a palpable increase in
the force required to close the door ac-
companied by a slight grinding sound just
before the door closes fully.
This is intentional and does not represent a
door fault.
• Select the desired heating programme (refer to
Sec. 5.1).
• Adjust the casting time as required (timer) (refer to
Sec. 5.2.2).
• Start the heating programme (refer to Sec. 5.2).
