5.1 Starting the furnace
5.1.1 Start-up
After the furnace has been switched on, the
unit undergoes a self-test, and if necessary, a
preheating cycle. The furnace selection
menu is shown on the display.
To reduce the moisture in the
press chamber (stone lining) the
vacuum pump is switched on
during the pre-heating phase, thus removing
the moist air.
As of Software Version V3.0 the vacuum
pump is kept on during the complete pre-
heating phase.
5.2 Introduction to the
operation "Pressing"
The EP 600 is designed for use with Ivoclar
Vivadent all-ceramic systems (IPS e.max,
IPS Empress). Therefore, the corresponding
parameters of the various programs have
already been set in the factory. All you have
to do is select the desired program for the
corresponding material using the function
keys F1 (104), F2 (105), F3 (106), or F4
(107). Next select whether you are using a
large or small investment ring.
After that, the display indicates the
corresponding program cycle diagram. The
program is started by pressing START.
The firing of the press cycle selected is
graphically displayed. The most important
parameters are visible on the display (74) at
all times.

soon as the press process has commenced,
the time passed since the beginning of the
press process is indicated.
Furthermore, the display indicates the
distance travelled by the press plunger in the
selected unit of measure since the beginning
of the press process, as well as the quality of
the vacuum in percent. If no program is in

between the various programs.
With F4, the parameters of the currently
