Call up and set the parameters at holding
level 1:
•
heating-up speed: 0°C/min. (= max.)
•
temperature of the holding level: see invest-
ment material
•
duration of the holding level: see investment
material
Set the parameters of holding levels 2, 3 and 4
to zero.
5.
Press
to set the extraction system to
con-
tinuous operation
. The display shows „SH”
(shock heat).
(Press again to deactivate.)
6.
Exit the programming mode:
Keep
depressed until the LED „°C”
lights
up

WARNING
Hazard from Shock heat
investment materials
So-called shock heat investment
materials are not heated up slowly,
but are placed in a furnace that has
been preheated to the final temper-
ature. As a result, the modelling
material burns atypically, i.e., if the
furnace door is opened, inflowing
oxygen can cause a darting flame!
•
Place
all moulds
in the furnace
within
10 seconds
- then keep the
furnace door closed for 15 minutes!
The cut-out of the
Regulus
furnace
extraction system is set to 600°C at
the factory. Shock heat investment
materials are placed in the furnace at
a higher temperature and produce
concentrated smoke gases in a short
space of time.
•
For shock heat investment materi-
als, the
Regulus
furnace extraction
system (REF 25750) must be
installed.
•
Regulus
must be set to
continuous
operation
(see below).
