387366-389 Operator Manual Sterilizer Operation
NOTE: This cycle is for sterilizing hard goods (e.g., empty glasses,
non-porous loads).
Run a GRAVITY CYCLE by pressing GRAVITY button from one of the
Operating Mode Screens (refer to S
ECTION 5.2, OPERATING MODES).
Press LEFT ARROW button to cancel selected cycle and return user
to Operating Mode screen.
Press START CYCLE.
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: Jacket charge phase continues until
jacket temperature is greater than set sterilizer temperature (example
121°C [250°F]). If separate steam selected, jacket charge phase
continues until jacket temperature is greater than set jacket
temperature (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 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.
CHARGE PHASE: Chamber charges with steam until chamber
temperature reaches sterilize temperature setpoint. If load option is
selected, phase holds until load temperature is greater than or equal
to sterilize temperature. Waste temperature is controlled to maintain
approximately 60°C (140°F).
STERILIZE PHASE: Chamber temperature controls at sterilize
temperature, plus overdrive (control temperature). Waste temperature
is controlled to maintain approximately 60°C (140°F).
FAST EXHAUST PHASE: Steam fast exhausts from chamber to
4.0 psig (0.28 bar).
VACUUM DRY PHASE: A vacuum is pulled in the chamber to
10.0 inHg (-0.34 bar; VACUUM DRY setpoint).
DRY PHASE: During dry phase, vacuum continues to be pulled to
system limit for dry time. If Dry Pressure Control is set to Vacuum Dry,
vacuum controls at vacuum dry setpoint of10.0 inHg (-0.34 bar).
AIR BREAK PHASE: Chamber vacuum air breaks to 2.0 inHg
(-0.07 bar) and is followed by a 10 second delay.
