Repairs
Repairs may be carried out solely by BEGO
customer service or by persons authorised by
BEGO customer service.
Metallic housings must be grounded properly so
as to prevent them from carrying current.
Otherwise they are extremely dangerous because
the housings may be live due to damage to the
machine! Since a check to ensure a de-energized
state is mandatory after every intervention in the
machine (Germany: check in accordance with DIN
VDE 0701-1), only qualified electricians may open
the machine!
Only BEGO replacement and wearing parts may be
used.
Installation
The unit is categorised under protection class 1 and
may only be connected to properly earthed power
sources (earth contact sockets).
When laying cables and hoses, ensure that they are
protected from hot components (e.g., moulds).
The cooling water temperature must never drop
below 10°C (50°F). Otherwise condensation water
may land on the hot moulds and vaporize explo-
sively.
Danger of burns when draining the cooling water! If
there was casting beforehand, the water can reach
temperatures of up to 70 °C.
Maintenance of safety-relevant compo-
nents
The unit has been designed for a service life of 10
years from the date of manufacture. No liability is
accepted for damages arising from operation of the

Unit description
NAUTILUS®CC plus and NAUTILUS®T - Compact tabletop casting units with inte-
grated cooling and user-friendly touchscreen
Both units utilise tried-and-tested HF vacuum
pressure casting with split crucible and have
integrated cooling as well as user-friendly touch-
screens.
Special emphasis was placed on security systems
with double redundancy. The closing of both casting
chambers is indicated by the double closing sound.
To lower energy consumption during longer periods
of non-use, both units have an eco mode that starts
after 3 minutes and ends after 10 minutes with the
switching off of the touchscreen illumination. In this
state, Nautilus®requires only 10 W. A quick touch
on the touchscreen is enough to make the unit
functional again after a few seconds.
New software versions can be transmitted via a
USB interface on the back of the unit which means
both casting units are, therefore, "updatable".
In addition, NAUTILUS®CC plus has a pyrometer
that not only measures the temperature of the melt
without contact. Together with specially developed
software, it also makes it possible to largely
automate the casting process. This makes repro-
ducible quality during casting possible, that can also
be documented and archived in the form of casting
protocols via the USB interface. In the event of
malfunctions, it is also possible to call up diagnostic
protocols and send them to the BEGO Service.
For easier handling of these additional features that
the USB interface provides, a USB docking station
and a USB stick is also supplied with NAUTILUS®
CC plus.
Determination of the casting temperature for dental alloys with NAUTILUS®CC
plus
The flowability of the melt and thus the casting
temperature are of decisive importance for the
quality of the cast object. The problems that may
result due to a melt that is too cold or too hot are
known in practice and described in the relevant liter-
ature and therefore they are not dealt with in detail
here.
Dental alloys have the property of not having a fixed
melting point, but a melting interval. Within the
melting interval alloys occur in viscous as well as in
crystalline form.
The melting interval can easily be identified in the
melting and hardening curve by the characteristic
"salient points", which result due to irregularities in
the temperature curve.
When an alloy is melted, the first "salient point" is
the so-called solidus and the second the liquidus,
from which point the alloy exists entirely as a melt.
These characteristics in the temperature curve are
utilized by NAUTILUS®CC plus by means of a
thermal analysis process.
To ensure optimal flowability of the melt in the dental
casting mould, the melt is heated beyond the
liquidus point. Depending on the casting method
and alloy, a temperature increase between 100°C
and 180°C has proven to be optimal in practice.
Corresponding recommendations on these casting
temperatures, which have been verified by empirical
tests as a rule, are given by the manufacturers of
alloys and casting equipment. With most casting
machines the accuracy for achieving the recom-
mended casting temperature through visual
assessment of the developing temperature still
depends on the individual skills of the user.

In the new NAUTILUS®CC plus casting machine,
by contrast, a mechanical measuring method is
used to determine the casting moment, enabling
precise determination of the casting temperature
within a very short time, even with small quantities
of alloy. At the same time the light information of the
melt is evaluated by means of an optical system and
a so-called pyrometer with a multichannel
measuring system and converted into temperature
values. The melting process is monitored on the
basis of the data captured in this way and casting
can be triggered automatically (on request also
manually) after the alloy-specific casting temper-
ature is reached. The measuring method applied is
able to compensate for influences due to fluctua-
tions in the light emission of the melt, such as those
occurring when the oxide skin opens during melting.
Through this innovative technology in the
NAUTILUS®CC plus the optimal casting tempera-
tures were determined for BEGO alloys and stored
in special casting programs for the machine control.
Thanks to the new measuring technique, it is now
possible to determine the casting temperatures very
reliably and on a reproducible basis. The standard
values recommended thus far for the casting
temperatures of BEGO alloys have consequently
been adapted to the newly defined values in some
cases and are summarized in the casting table of
this operating manual.
If alloys of other manufacturers are used in the
NAUTILUS®CC plus, the casting program of a
BEGO alloy can be copied with maximum
conformity to alloy composition and properties. Now
only the casting temperature and the name of the
non-BEGO alloy have to be adapted according to
the respective manufacturer's specifications. Users
can manually cast non-BEGO alloys for which
casting temperatures are lacking according to their
visual impression and then utilize the displayed
temperature to create their own casting programs
for automatic operation with these alloys. The
procedure for creating a casting program for a non-
BEGO alloy in the program memory of the
NAUTILUS®CC plus involves only a few steps and
is described in the operating manual.

Nautilus®CC plus
NAUTILUS®CC plus (CC = Cast Control) is a
compact benchtop unit for vacuum pressure casting
with induction heating in the dental laboratory.
Sophisticated software and non-contact temper-
ature measurement with the help of a so-called
multichannel pyrometer enable automatic casting
and at the same time optimal, reproducible casting
results.

Overview
After switching on the unit, the following functions
can be called up via the touchscreen:
Automatic casting
In the automatic mode casting is carried out
automatically at the optimal casting moment without
any action on the part of the operator. It is only
necessary to call up the program location of the
alloy, which can be found in the program tables.
In the automatic mode it is also possible to intervene
manually, if desired, for example to trigger casting
before the machine would do it.
Manual casting
In the manual mode casting is carried out at the
push of a button. The temperature measurement
also takes place in the manual mode with pyrometer
support and it reminds the operator by means of
additional optical signals that the casting temper-
ature has been reached.
As a rule, manual casting only takes place in order
to create a program for a non-BEGO alloy (with
pyrometer, see page 26) or represents an
"emergency operation" if the pyrometer is defective
(without pyrometer).
Settings
Here, for example, new program locations for non-
BEGO alloys are created.
USB
With the aid of the USB stick and the USB docking
station (included in delivery), casting protocols can
be saved and printed or archived via a PC. In the
event of malfunction, diagnostic protocols can be
called up and sent to the BEGO Service. The unit
can be "updated" with the new software versions
from the BEGO homepage.

NAUTILUS®T does not have a pyrometer and,
thus, any temperature measurement. The casting
must be carried out manually while observing the
melt. Casting and diagnostic protocols without

Basic principles: Wax-up
After the crucible is opened, the melt flows into the
mould through gravity and immediately fills the
sprues. Immediately after that the entire mould
cavity is swiftly filled with the hot melt by means of
compressed air. The object should first harden and
must enable subsequent suction of the liquid melt
out of the reservoir of the sprues. The following rules
must always be observed for this purpose.
BEGO base socket mould formers are matched to
the flow of the melt from Nautilus®crucibles and
should therefore be used.
Do not provide with vents. Air vents cause the
compressed air to be fed incorrectly during
pressing.
The object should first harden and enable subse-
quent suction of the liquid melt from the heat centre
of the mould.
For this reason keep the spacing between the object
and the mould bottom and mould wall small (5 mm).
Arrange bridges in a ring shape at the mould wall.
Partial denture
Follow the illustrations and the instructions of the
alloy manufacturer when dimensioning the sprues.

but first fills the distribution channel.
c) Reinforce distribution channel in the case
of full pontics (the volume of the reinforce-
ment must correspond at least to the vol-
ume of the full pontics).
d) Dimension the distribution channel gener-
ously and allow it to project to enable sub-
sequent suction of liquid melt.
e) Maintain small spacing between object and
mould bottom and wall (5 mm).
Follow the instructions of the alloy manufacturer
with regard to dimensioning sprue systems and
sprues.
Crowns
a) Prevent the melt from flowing in directly
through sinuous sprue system.
b) Extend sprue beyond the sprue system of
the crown.
c) Maintain small spacing between object and
mould bottom and wall (5 mm).
Follow the instructions of the alloy manufacturer
with regard to dimensioning sprue systems and
sprues.

Basic principles: Crucible
Recommendation: Only use BEGO crucibles
(identifiable by the BEGO logo)!
Always use crucible and inserts for the same alloy.
(Crucibles can be written on with a pencil.)
WARNING
Risk of burns due to hot parts!
• Only touch the crucible handles with
safety gloves.
• Grasp crucible inserts only with
tweezers.
NOTE
Crucibles of other manufacturers frequently have
incorrect dimensions. This leads to faulty casting
if the crucible opens too late or the melt leaves
the crucible too early.
Screw the handles firmly onto the crucible all the
way to the stop.
WARNING
ATTENTION
Inserts (made of graphite or glassy
carbon) require ceramic handles!
When inserts are used, the handles
become extremely hot: plastic
handles would melt!
