If the self-test has been successful,
the stand-by screen will appear in
the display and the desired program can be selected using the
program selection keys.
Once the furnace head has been
opened and the loaded sinter tray
placed, the program can be started
using the START key. For that purpose, the START key is shown in
the recommendation area.
6.1.2 Program progress indicator
When the program is started using the START key, the program
progress indicator is shown in the display.
Note:
For safety reasons, the furnace head can only be
opened once the temperature has dropped below
600 °C/1112 °F.
a)
b)
d)
e)
c)
f)
CAD/CAM fabricated support structures (for large frameworks with a
pronounced curvature) should not be separated for the sintering
process. In order to achieve optimum sintering results, the objects
should be placed on their occlusal or labial surface (not on the
cervical margin). Furthermore, no objects should be placed on the
groove in the sinter tray, if possible.
After that, the sinter tray is placed in the center of the sinter
chamber by means of the sinter tray fork (101).
Please read the following processing notes very
carefully
The individual pre-drying times of the ZrO2 objects must
be observed. They depend on the size of the restoration
and the pre-drying temperature. For more detailed information,
please refer to the instructions for use of the corresponding material.
If the Colouring Liquids are used, several points must be
observed:
– The restorations stained with Colouring Liquid must be
adequately pre-dried in a pre-drying furnace. Air drying is
not sufficient in these cases and may result in cracks in
the objects during the sintering process.
– After the sintering process, clean contaminated areas of the
furnace with a soft cloth.
– In case of severe contamination of the sinter chamber or the
insulation, conduct a cleaning firing.
Once the sintering process is completed, the sinter tray is removed
from the furnace using the sinter
tray fork. If the tray is placed on
the cooling tray, make sure that it
is securely positioned.
For safety reasons,
always use the sinter
tray fork when placing
the sinter tray in or
removing it from the
furnace.
The following information is provided:
a) Program status
b) Remaining time (hh:mm)
c) Current temperature
d) Program number
e) Program name
f) Progress bar
6.2 Loading the Programat S1
The sinter tray (100) holds up to approximately 20 single-tooth
restorations. Make sure that the objects do not touch in order to
prevent them from sintering together. The ZrO2 sinter beads are
usually not required for this process.
In case of stack milling, the individual objects have to be separated
from the stack, the corresponding margins adjusted and the
attachment points smoothed out by grinding.
6.3 Sintering using a standard program

7. Maintenance, Cleaning and Diagnosis
This chapter describes the user maintenance and cleaning procedures
for the Programat S1. All the other tasks must be performed by
qualified service personnel at a certified Ivoclar Vivadent Service
Center.
7.1 Cleaning of the sintering chamber and the heating
elements
7.1.1 Visual inspection of the sintering chamber
Inspect the sintering chamber visually prior to every sintering
procedure. No foreign objects or dirt particles must be present in the
sintering chamber during the sintering procedure.
Contaminations may be due to a chipping of the oxide / protective
layer of the heating element surface, among others. This type of
contamination may have an effect on the optical properties (discolouration) of the sintered object.
Contaminations resulting from chipping-off of the oxide layer can be
classified as follows:
Type of
contamination
Glass particlesThe insulation of the lower part of the
Fine glass dustThe insulation of the lower part of the
Indicator

particles (see image a).
furnace and the cooling tray show residue
of fine glass dust. This type of contamination is more difficult to discern.
7.1.2 Cleaning of the sintering chamber
Use the enclosed cleaning brush (102) for cleaning. Do not use
compressed air for cleaning under any circumstances. After cleaning,
conduct a cycle with the Program 1 (IPS e.max ZirCAD crowns) with
the firing chamber empty. In case of severe contamination it is recommended to conduct the cleaning program (see section 7.1.3).
102
7.1.3 Cleaning of the heating elements
The cleaning program recreates the chipped off oxide / protective
layer on the heating elements.
If no smooth protective layer is visible on the heating elements after
a cleaning firing, several subsequent cleaning firings may be
necessary. Do not place ZrO

program.
objects in the furnace for these firings.
2
a)
If glass particles or fine glass dust are noticed during the visual
inspection, the sintering chamber needs to be cleaned (see section
7.1.2) and a firing cycle with Program 1 (IPS e.max ZirCAD crown)
must be conducted with an empty firing chamber. For this cycle, no
ZrO
objects must be placed in the furnace.
2
Large parts of the protective layer on the left heating element have
chipped off. The heating element on the right side is in a sound,
stable condition and shows an intact oxide / protective layer. The
cleaning program must be repeated until the surface is free from
contamination and appears glassy.
25
7.2 Monitoring and maintenance
The time for these maintenance procedures depends on the
frequency of use and the working habits of the users. For that
reason, the recommended times are only approximations.
This furnace has been developed for typical use in dental
laboratories. If the product is used in a production enter-
premature ageing of the expendable parts has to be expected.
The expendable parts are as follows:
– Heating muffle
– Insulation material
Expendable parts are not covered by the warranty. Please also
observe the shorter service and maintenance intervals.

Check the insulation for cracks and damages. If the insulation is worn down
it has to be replaced by a certified Ivoclar Vivadent Service Centre. Fine hairline cracks on the surface of the insulation are harmless and do not
influence the function of the furnace in a negative fashion.
Check the keypad for visible damage. If the keypad is damaged, it has to be
replaced by a certified Ivoclar Vivadent Service Centre.
Check temperature. Use the temperature checking set to check and adjust
the temperature in the furnace.

If the furnace head is replaced with a furnace head from
another Programat S1, calibration is required.
7.3 Cleaning
The furnace may only be cleaned when it is cool, since
there is a burn hazard. Do not use any cleaning solutions.
Disconnect the furnace from the power source before
cleaning.
The following parts have to be cleaned from time to time:

7.4 Test programs
Press the Settings key and scroll to the desired test program using
the cursor keys.
Heater test program
The heater test automatically checks the heating system. The test
should only be performed with the firing chamber empty, since any
mass placed in the furnace (e.g. sinter tray) would influence the
result.
Keypad test program
Each pressing of a key results in a short beep. The keypad test can
be closed using the ESC key.
Cleaning program
The heating elements are „cleaned“ and/or regenerated using the
cleaning program.
4. After the end of the program, carefully remove the sintered sinter
ring and allow it to cool to room temperature on the cooling tray.
5. Place the cool ring on an even
surface and determine the exact
diameter using the slide gauge.
Make sure that the ring is flush
with the two arms of the slide
gauge. Conduct the
measurement in that area of
the ring, where the batch
number (c) has been stamped
into the ring.
c)
7.5 Stand-by
We recommend keeping the furnace head closed during stand-by to
prevent damage.
7.6 Temperature calibration
The temperature level in the sintering chamber may change after
prolonged operating hours (e.g. by contamination, wear and tear of
the heating elements etc.). For optimum function, regular recalibration is required. The Temperature Checking Set S1 has been specially
developed for this purpose. This set is used to calibrate the temperature of your sinter furnace.
The calibration with sinter rings enables the verification of the holding temperature of 1500 °C/2732 °F required for sintering the ZrO
blocks in the sintering chamber.
During the sinter process, the rings change their dimensions due to
shrinkage. The shrinkage of the sinter rings is decisive for the correction value of the furnace and can be found on the conversion table.
For calibration, you need sinter rings, a measuring device (slide
gauge) and a conversion table (enclosed in the Temperature Checking Set 1).
Procedure:
1. Press the Settings key (78) to
access the Settings screen. Select
„Temperature Calibration“ using
the cursor keys (79/80). The
following display appears:
2
6. Find the measured diameter in the conversion table and read off
the corresponding temperature. Only if the deviations is more
than 10 °C / 18°F must the furnace be readjusted.
7. If the temperature difference is higher than 10 °C / 18 °F (target
temperature = 1500 °C/2732 °F) the correction value can be
transferred to the furnace with the help of the -/+ keys (76/77).
Each keystroke changes the furnace temperature by 1 °C. Once
the desired correction value has been entered, the program can
be closed by pressing the ESC key (71).
Calibration is now complete. Close the furnace head or select a
sintering program.
For further information about the calibration, please refer
to the note accompanying the Temperature Checking Set
S1.
7.7 Service Hint
When the Service Hint appears for the first time (Hint 1700), 2 years
have passed or the heating elements have been in use for more than
1200 firing hours. For this reason, Ivoclar Vivadent recommends a
maintenance and service procedure. For further information, please
refer to the Equipment Service Passport. The interval until the next
appearance of the Service Hint can be selected in the settings (see
Chapter 5.6.1).
The calibration program is
selected with the ENTER key.
The following display appears:
2. Position the sinter ring (a) in the
center of the sinter tray (b)
