Pressure build-up using the MultiPress S with hand pump:
In the MultiPress S with hand pump, the pressure must be built up
manually at the beginning of each stage and corrected during the entire
program sequence(see chapter 6.8‚ "Operating the hand pump", on
page 54).
› As soon as the actual and target values appear, immediately start
pumping until the target value on the display is shown on the
manometer.
› In order to maintain the target pressure, correct the pressure during
the entire pressing.
At the end of the prepressing stage, a repeated acoustic signal will sound
indicating the beginning of the main pressing stage. In the pressing stage
display box, " main press " is displayed.
› Keep pumping until the target pressure is shown on the manometer.
› Keep controlling the pressure and correct it, if necessary, by
additional pumping.
After the main pressing stage is complete, the cooling stage is started
automatically, and the fan is switched on. During this, the target pressure
is displayed, which must be maintained by additionally pumping by hand.
During the cooling stage, it is particularly important to keep the pressure
at the target pressure level. Material-related, the pressure will drop
particularly strongly at the beginning of the cooling stage, at which point it
must be increased by additional pumping.
