The following instructions assume a PSS5 control system
on a PRIMUS sterilizer or a retrofitted PSS5 control kit.
Primary Settings

The following setpoints are needed to run a vacuum cycle
Set the cycle name to VACUUM
Set the number of PRE-VACS at 3 (3 pressure and vacuum pulses) (A minimum of 1 and a maximum of 6 PRE-VACS are allowed with 3 PRE-VACS being standard)
Set the number of POSTVACS at 1 (This enables a post sterilization dry phase)
Set the POSTVACS setpoint at -10.0 (10 inches of mercury vacuum)
If running a 270°F – 273°F (132.2°C) sterilize cycle, use a PRECHARGE PRESS of 20 psig
If running a 250°F (121.1°C) sterilize cycle, use a PRECHARGE PRESS of 10 psig
Typically, set a PREVAC VAC TIME of 1:30
VAC TIME will only occur on the third through sixth PRE-VACS
Set a PREVAC VAC POINT of -20.0 (20 inches of mercury vacuum)
Set a PURGE of 1:30
Refer to the printout below for rough guidelines on other settings.
Depending on what is being sterilized, each end user facility must establish the Sterilize Time and Temperature. ADD PHOTOS
