4. Front panel
The front panel has the following operating elements:
On/off switch
Display indicating heating/cooling times and pressure
Dual LED: green = availability , red = heating
Push button "air" for depressurization /control of working pressure
Blue LED indicating cooling time (continuous light) and depressurization (flashing light)
Push button "code scan" for scan activation
5. Main connection
Connect the MINISTAR S ® machine to the corresponding network by plugging in the original power cable on the back of the machine
refer to connection to the local network in the safety instructions). Two fuses are built in to protect the machine from high voltage (230 V version). To
exchange the fuses press the little clip below the connector and remove the fuse compartment
built in two separate fuse covers , which can be unscrewed (see fig 2 and 3). Please use the T4A fuse (3100.940) for 230 V device, the T10A fuse
(3101.941) for 115 V devices and the TT10A fuse (3100.941) for 100 V devices.
6. Compressed air connection
A 20 bar air hose with filter element and hose clip (DN 7.2/6 mm tube inner diameter) is permanently connected with the device and should not
be replaced. Use the 20 bar tube and optionally a quick connect coupling (DN 7.2/6 mm tube inner diameter). The working pressure is adjusted to
4 bar/58 psi, continuously indicated on the display and should not be changed as it is calibrated to achieve the best pressure moulding results.
However, if you wish to lower the working pressure, it can be adjusted using the pressure regulator
regulator is unlocked by pulling and turning ( ). The pressure regulator is locked again by pushing it in. If the pressure exceeds 4.5 bar/65 psi
contrary to our specifications the security valve will be set into action (depressurisation noise).
7. Basic position
Infrared heater is swivelled back to the stop, pressure chamber
(12 o'clock position). Please refer to fig.1
8. Switching on the unit
The unit is put into operation with the on/off switch , runs through a test and setting mode for approx. 10 sec. and then shows the standard dia-
logue, which is the starting point for any pressure moulding operation. Programming is done using the touch panel
display .
9. Positioning blanks
All round blanks and foils with diameter of 125 mm and thickness of 0.1 to 5.0 mm can be pressed in the MINISTAR S
chamber by swivelling it to the left side, take off the locking ring
adjustment ring visible in the pressure chamber and lock the device by putting on the sealing ring and turning the handle to the 6 o'clock position
(see fig. 5).
10. Preparing the model
When using hard or hard-elastic material, models are placed into the model cup
ing soft elastic material, models can be placed on the working platform
right towards the locking shaft or to the left towards the pressure chamber
model platform can be removed using the pellet brush with integrated magnet (see fig. 4). The removable pellet container
steel pellets for model embedding. By removing the pellet container, the circumferential groove for the stainless steel pellets is simultaneously closed
by means of a movable slider (see fig. 6).
11. Scanning/programming by setting code or time
The machine is activated by pressing the illuminated on/off switch
Our pressure moulding material has a 3-digit-code where all required information on temperature, heating time and cooling time is programmed. This
code is printed in plain text and as bar code on our pressure moulding blanks or foils, except for material with thicknesses below 0.1 and 0.15 mm.
After selecting your material, press the button „code/scan"
.
The scanner is now activated. Present only now the bar code of the chosen material under the scanner until you hear a beep. Alternatively, the
code can be programmed manually.
Enter the digits and confirm by pressing the button „code/scan"
press the key with the clock symbol , enter the required heating time and confirm by pressing the button

12. Heating
After programming, directly swivel the infrared heater
The colour of the heater might vary from bright to dark.
13. Thermoforming
Acoustic signals indicate the end of the heating process (+5 sec. to 0 sec. = beeps/0 sec. to -5 sec. = continuous tone). At 0 sec. the infrared heater
should be swivelled back, at -5 sec. the heater switches off for safety reasons. Swivel pressure chamber

14. Depressurising
, (please also
Optical signals (blue flashing LED) and acoustic signals (4 beeping sounds) indicate the end of the cooling time. Press the flashing button „air"

15. Special programs using the heating support
If you want to fabricate positioners, mouth guards or splints, you can manually programme time intervals of 60/120/180/240 seconds with the pres-
sure chamber closed and the locking shaft open. These intervals are chosen to heat up or to seal the occlusal surfaces using the heating support.
(REF 3452) (see fig. 7). Once the heating times have been entered, the infrared heater with attached heating support is swivelled into the heating
position. This process can be carried out several times depending on the thickness of the material.
16. Service/Maintenance
The MINISTAR S ® machine is basically maintenance free. Please only check the air hose incl. filter element regularly for deposits or moisture. The
filter can be replaced if necessary. The model cup
parts of the pressure chamber should be cleaned regularly to obtain the best heating results. For cleaning remove the aluminium adjusting ring
from the pressure chamber
adjusting ring back on the rivets and springs ensuring that the sealing ring faces the top and that the whole unit is movable. Please also refer to the
enclosed „Guideline to solve technical problems".
