387366-389 Operator Manual Sterilizer Operation
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.
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).
NOTE: At this point, either the Fast Exhaust Phase or Slow Exhaust
Phase selection applies. The phase sequences of the two options
follow below.
==================================================
FAST EXHAUST PHASE (
ALTETRNATIVE TO SLOW EXHAUST PHASE)
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 the limit of the system for dry time.
AIR BREAK PHASE: Chamber vacuum air breaks to 2.0 inHg
(-0.07 bar).
DEACTIVATE SEAL PHASE: Door unseals until seal pressure
switch opens, and 20 seconds has elapsed.
COMPLETE PHASE: Cycle is complete. Open door and unload
chamber. Once door is open, display returns to main operating
mode screen.
===========================================
SLOW EXHAUST PHASE (
ALTETRNATIVE TO FAST EXHAUST PHASE)
SLOW EXHAUST PHASE: Steam slowly exhausts from chamber
to 5.0 inHg (0.17 bar). Pressure rate controls at 1.6 psi/minute (0.11
bar) to 4.2 psig (0.29 bar) and at 0.6 psi/minute (0.04 bar) to
5.0 inHg (0.17 bar).
VAPOR REMOVAL PHASE: Vapors in chamber vents for 10
minutes.
PHASE: Door unseals until seal pressure switch opens and 20
seconds has elapsed.
COMPLETE PHASE: Cycle is complete. Open door and unload
chamber.
NOTE: Aside form the tape header, Decon Cycle print tapes look like
Prevac Cycle tapes; and for that reason have not been duplicated
here.
