12. Heating
After programming, directly swivel the infrared heater 1 over the fixed material. The temperature is regulated automatically by a thermo element.
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 2 by 180° to the right (make sure the seal-
ing surface is clean) and turn the locking shaft C 180° to the front. This ventilates the pressure chamber and automatically starts the cooling time,
signalled by blue LED.
14. Depressurising
Optical signals (blue flashing LED) and acoustic signals (4 beeping sounds) indicate the end of the cooling time. Press the flashing button „air" to
depressurise the pressure chamber. After approx. 3 seconds 4 beeping sounds indicate the end of depressurising. Now turn the locking shaft 
180° backwards, push the locking ring K to the left and open the pressure chamber 2 (see fig. 8). Remove the model. The machine can
now be used for the next pressure moulding operation.
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  with air holes and model platform 6 can be cleaned with air nozzle or steam jet. The reflecting
parts of the pressure chamber should be cleaned regularly to obtain the best heating results. For cleaning remove the aluminium adjusting ring L
from the pressure chamber 2. The sealing surfaces, the sealing ring and the 4 rivets and springs should be cleaned and lightly greased. Place the
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".
