Vacfomat V9

8. Deviations from regular operation

8.1. Changing specified times
The specified times can be prolonged
or shortened individually if required.
For this purpose, the new time to be
entered is changed by means of the
rotary/push button (3) until the new
time is shown on the display (4) in
flashing mode. Before it is used for
the first time, it must be approved by
the operator by pressing the rotary/

Tip:
The performance of the heating may
decrease slightly after 2000 operat-
ing hours. By prolonging the heating
times by five to ten (5–10) seconds,
optimum thermoforming results can
be attained again.
The specified times are average values
and intended for general use.
In case of extreme undercut areas
or very high models, a prolongation
of the heating time can optimise the
results.
ing the rotary/push button (3) for at
least two (2) seconds.
Only use the fuse strength
specified on the back.
After the fuse has been exchanged,
insert the fuse carrier into the housing
by applying slight pressure until you
notice that the fixation has engaged.
10. Resetting the temperature monitor / exchanging an
infrared heating element
Before accessing the inner parts of the device, the mains plug must
be pulled out.
