Info
For safety reasons the quartz
radiator is equipped with a final
switch and only works in swivelled
in position after having started a
programme.
If the quartz radiator is swivelled
outwards after having started a
programme, the heating process
will be interrupted automatically.
The indication in the display (a)
will stop and show the remain-
ing time. By swivelling the quartz
radiator back in the programme
will be re-activated.
Attention! The swivelling hous­
ing of the heating element
reaches high temperatures.
8.4 Thermoforming
After the heating time has elapsed there
will be an acoustic signal; the heat-
ing time in the display will be 00:00.
Heating and LED illumination will be
switched off automatically.Pull the heat-
ing (4) with the right hand at the knob
rod (5) as far as it will go to the front
and hold it tight.
Then push the push button (8) with the
left hand at the left side of the housing.
The piston will move downwards and
close the pressure chamber; an acoustic
signal will be heard.
Info
The closing pressure of the down-
wards moving piston is always
higher than the forming pressure!

Therefore it must not be touched –
even not for short moments. After
the adjusted time has elapsed the
indicator (a) in the display will
stop and count the duration after
termination of the heating time.
This process may be stopped by
abort (long pressing of button 8)
or by successive thermoforming.
The downwards moving piston is
equipped with a dual electronic
safety feature and can only be acti-
vated, if the unit is operated with
two hands at the same time (two-
hand control). Always make sure
that no objects are in the contact
area between piston and F insert
while the piston is closing!
Hold both buttons until the pressure bar
in the display (g) shows the adjusted
minimum of 29 psi (2 bars). Then
release the push button (8) and finally
the knob rod of the heating (5). After
having reached the 29 psi (2 bar) mark
the pressure will automatically rise up
to the pre-adjustment.
