Unwrapped instruments cycle (20 x 20).
(a)
Ready. When the proper conditions are reached, the unit is ready.
(b) Conditioning. Steam purges the chamber of air for 90 seconds.
The load is then conditioned for two successive pressure and negative pulses.
(c) Exposure. Steam heats and pressurizes the chamber at the
required temperature for the selected time.
(d) Exhaust. Chamber pressure is vented, and a vacuum is drawn to
dry the load for the selected time. After the drying time expires, the chamber is returned
to atmospheric pressure.
(e) Complete. The gasket retracts in 30 seconds, and a buzzer sounds
to alert the operator to manually open the door. On a double door unit, press either
unseal door switch after the buzzer sounds for both gaskets to retract.
(4)
Liquids cycle.
(a)
Ready. When proper conditions are reached, the unit is ready.
(b) Conditioning. Steam purges the chamber of air for a set time
depending on the size of the sterilizer. The chamber is heated to the selected
temperature.
(c)
Exposure. The chamber is held at the required temperature for the
selected time.
(d) Exhaust. The chamber and jacket pressure are slowly reduced to
atmospheric pressure to avoid agitation of the liquids.
(e) Complete. The gasket retracts in 30 seconds, and a buzzer
sounds. On a double door unit, press either unseal door switch after the buzzer sounds
for both gaskets to retract.

CYCLE PHASE DESCRIPTIONS
Paragraph 1-5 provided you an overview of the cycle phases. This paragraph
discusses the step-by-step processes involved during each phase throughout the entire
cycle. The unit is pre-programmed to execute each phase automatically after you press
the cycle start switch (labeled "P" in figure 1-5).
