Operations sequence:
•
(PV, pre-vacuum models only)
Pulse low/Pulse high:
at one pulse it
will build vacuum down to 25 kPa.
All exhaust from the chamber is
performed through the bio-hazard filter.
•
Water Inlet
: Water enters the chamber
•
Heating:
The chamber is heated by actuation of electrical heaters
until the sterilization temperature is reached.
•
Sterilization:
Sterilization temperature is maintained constant during
the sterilization time.
•
Cooling:
N/A
•
Slow Exhaust:
Steam is exhausted from the chamber at a slow rate,
until it reaches the pressure of 30 kPa above the ambient pressure.
Then steam is exhausted out of the chamber at a fast rate until
pressure decreases to ambient pressure.
Note:
If the cycle fails, fast exhaust is performed through the bio-hazard
filter. Some water may remain in the chamber after a failed cycle. To
remove such water, press Start and repeat the cycle. If the problem
persists, call for service.
•
Drying:
N/A
•
Ending:
The system checks that End temperature and End pressure
have been reached, and then releases the door.
