7.4 Opening of the pressure chamber

In order to attain a complete cool down
of the thermoforming blank the valve
at the tension ring (12) is to be opened
slightly after 2/3 of the adjusted cooling
time. Through this the warm air inside
the piston will be released and replaced
by cool air due to the automatic pres-
sure regulation. After the cooling time
has elapsed pull the heating handle (5)
as far as it will go and maintain it in this
position (approx. 3 seconds) until an
acoustic signal can be heard. Release
the heating handle and the pressure
will be relieved automatically.
Then swivel the pressure chamber into
its original position by leading back the
activation lever (34).
Swivel out the plate reception (11) at
the corresponding handle (10) and
remove tension ring and thermoformed
result.
