Sterilizer Operation Operator Manual 387366-389
The optional Decontamination Cycle, also referred to as a Decon
Cycle, is a specialized cycle designed for processing loads in BSL-3
and BSL-4 applications. The Decontamination Cycle removes the risk
of dangerous organisms becoming aerosolized in the drain or
escaping the autoclave in the initial phases of a Sterilization Cycle.
This is accomplished through removing air through a 0.2 micron filter
and trapping effluent and sterilizing it in the process of the cycle and
makes use of a fast or slow exhaust phase.
Start a Decon Cycle by pressing DECON 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 cycle selected and return to
Operating Mode screen.
Press DECON button to start the Decon Cycle. Cycle phases are as
follows:
NOTE: If CLOSE DOOR(S) button is shown, close door(s). Refer to
S
ECTION 5.3, STATUS BUTTONS, for description of buttons.
JACKET CHARGE PHASE: Phase continues until jacket temperature
is greater than set sterilizer temperature (example: 121.0°C [250.0°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 phase is complete.
PURGE PHASE: Steam enters chamber from jacket to control
pressure at 6 psig (0.41 bar). Fast exhaust and water ejector aid in
removing air from chamber.
PULSE EXHAUST PHASE: Chamber exhausts to 4.0 psig (0.28 bar)
(0.27 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] [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.
The Filter Life (if shown) starts at 0 and increments each minute during the Decon
Cycle Sterilize phase. 545 would represent 545 minutes in the Decon Sterilize
phase. After a pre-determined value, filter needs to be replaced. Only a qualified
Service Technician should replace the filter. See Maintenance Manual for filter
replacement.
FILTER LIFE value can be modified in Supervisor
Mode (
SPECIAL CYCLES button).
