JACKET CHARGE PHASE: Jacket charge phase continues until
jacket temperature is greater than set sterilize 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: 15°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.
PREHEAT: The product in chamber is heated to 60°C (140°F) for 90
minutes using jacket heat only (no direct steam). The chamber
temperature is used to determine 60°C (140°F) temperature.
PURGE PHASE: Steam enters chamber from jacket (or direct with
separate steam) to control pressure at 6 psig (0.41 bar). Fast exhaust
aids in removing air from chamber. The duration is 5 minutes.
PULSE EXHAUST PHASE: Chamber exhaust to 4.0 psig (0.28 bar)
with an exhaust rate of 1 psi per minute. Jacket temperature is
controlled to maintain approximately 122.5°C (253.0°F) in jacket. Units
with separate steam control jacket at 115°C (239.0°F).
