Vacuum test: cycle for autoclave pneumatic seal verification (duration approx. 16 min). A
vacuum and electronic controls verify pneumatic seal efficiency in the sterilization
chamber.
B&D / Helix test: cycle for sterilization efficiency verification, cycle parameters analogous
to those used in the “CLASS B 134°C” cycle but with 3.5 minutes of sterilization time and
limited drying. To be performed together with related system tests.
5.5 PREHEATING
Preheating requires that the machine be brought to a useful temperature range for starting
a sterilization cycle.
In this phase, the heater in the steam generator is activated.
Once useful conditions are reached, resistance start-up is modulated to keep the machine
ready for use for a period of approx. 1 hour.
The preheating phase is immediately active upon machine turn-on (the turn-on time, or
"wake", can also be programmed - see the "SETTINGS-WAKE" paragraph).
It is possible to turn on a sterilization cycle (or test) even if preheating has not been
completed. In this case, sterilization will require additional preheating time, managing the
wait time automatically.
fig. 16 – “"preheating" icon
The "preheating" icon appears on the lower right side of the display to indicate preheating
status
If the icon is flashing, preheating is in progress.
If the icon does not appear, the machine is ready and jacket temperature has
reached a suitable level for immediate cycle turn-on.
After a certain period without use, approximately 1 hour, the machine will enter into
energy saving or “stand-by” mode. In this phase, the heater will not be activated. The
chamber, jacket and generator temperatures will gradually decrease over time.
It is possible to select and activate a sterilization cycle even from the stand-by mode. The
machine will then restart preheating and will autonomously manage cycle turn-on.
