Sterilizer Operation Operator Manual 387366-389
NOTE: The Prevac Cycle is for sterilizing wrapped goods (e.g.,
instrument trays, textile packs and instrument containers) and for
sterilizing liquids in heat-resistant containers with vented closure with
slow exhaust option.
Run a PREVAC CYCLE by pressing PREVAC button from one of the
operating mode screens (refer to S
ECTION 5.2, OPERATING MODES). The
following screen appears (values are examples only):
Press LEFT ARROW button to cancel selected cycle and return user
to Operating Mode Screen.

ECTION 5.3, STATUS BUTTONS, for description of buttons.
JACKET CHARGE PHASE: Jacket charge phase continues until
jacket temperature is greater than set sterilizer temperature (example
121.0°C (250.0°F). If separate steam selected, jacket charge phase
continues until jacket temperature is greater than set jacket
temperature, for example: 115°C (239°F).
ACTIVATE SEAL PHASE: Door gasket seals with steam until door
seal switch is closed. An additional 20 seconds elapses, after seal
switch is closed, before the phase is complete.
PURGE PHASE: Steam enters chamber from jacket to control
pressure at 6 psig (0.41 bar). Fast exhaust aids in removing air from
chamber.
PULSE EXHAUST PHASE: Chamber exhausts to 4.0 psig (0.28 bar).
Waste temperature is controlled to maintain approximately 60°C
(140°F). Jacket temperature is controlled to maintain approximately
122.5°C (253.0°F) in jacket.
PULSE EVACUATE PHASE: Chamber evacuates to PULSE VACUUM
setpoint (default 10.0 inHg [-0.34 bar]). Waste temperature is
controlled to maintain approximately 60°C (140°F). Jacket temperature
is controlled to maintain approximately 122.5°C (253.0°F) in jacket.
PULSE CHARGE PHASE: Chamber charges with steam to PULSE
CHARGE setpoint (default 26.0 psig [0.34 bar]). PULSE EXHAUST,
PULSE EVACUATE and PULSE CHARGE repeats for number of pulses
selected.
