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 7, (please also
®
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 8. For the 100 V/115 V versions, these fuses are
built in two separate fuse covers R, 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 9 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 J on the back of the machine. The pressure
regulator is unlocked by pulling and turning (
contrary to our specifications the security valve will be set into action (depressurisation noise).
7. Basic position
Infrared heater 1 is swivelled back to the stop, pressure chamber 2 is opened to the left, locking ring handle  is swivelled back to the stop
(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  or sanner  and shown in
the 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 2 by swivelling it to the left side, take off the locking ring K by turning it in the 5 o'clock position. Place the blank on the O-ring of the
adjustment ring L 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 , filled up to its upper rim with stainless steel pellets. When us-
ing soft elastic material, models can be placed on the working platform 6.In both cases, the model should be placed with the incisors facing to the
right towards the locking shaft  or to the left towards the pressure chamber 2 to ensure uniform material thickness between the quadrants. The
model platform can be removed using the pellet brush with integrated magnet (see fig. 4). The removable pellet container 5 contains the stainless
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 . When switching on the machine, make sure it is in basic position (see fig. 1).
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"  again. You also have the option to enter the heating times manually. Doing so,
press the key with the clock symbol , enter the required heating time and confirm by pressing the button  again.
). The pressure regulator is locked again by pushing it in. If the pressure exceeds 4.5 bar/65 psi
