•
The required evacuation pressures for the individual sub-atmospheric pulses
–
P37, P38, P40, P41 for cold starts
–
P1, P2, P21, P22 for hot starts
•
The required evacuation pressure (P17) for the vacuum test
•
The required evacuation pressure (P12) for evacuation / pressure relief
•
The required minimum pressure for drying (P3).
Causes of the problem / Correction of the problem
Action / checking by operating staff:
•
Check for defects and for soiling of the door seal and the sealing surfaces of the sterilization chamber,
and on the round plate around the door of the sterilization chamber. Repair and clean if necessary.
•
Check to make sure that the autoclave is properly set up (it must be installed with a tilt (at slope), as
described in the operating instructions).
•
Check to make sure that the condensate drain at the bottom of the sterilization chamber is not stopped.
It can be stopped if instruments, filter paper, etc. fall onto the bottom of the chamber.
•
Check for the following:
–
If you are using the internal system for supply of demineralised water, check to make sure that the
pressure-release pipe is not stopped.
–
If you are using an external waste-water connection that empties into the building waste-water
system, check to make sure that this drain pipe does not have a kink (make sure the water can
flow freely out).
