Remove the bellows dome by turning it counterclockwise and lifting it away from the breathing system.
Detach the bellows from the base plate.
Detach the top plate from the bellows.

Remove flow sensors by turning the locking nuts counterclockwise. Pull out the inspiration and expiration connectors together with their locking nuts. And then pull out the flow sensors horizontally.
Disconnect the oxygen sensor cable from the main unit. Then hold the oxygen sensor and pull straight out firmly from the breathing system block.
Loosen the base collar of the APL valve by turning the collar (not the valve knob) counterclockwise until it is no longer threaded. Then, firmly pull the APL valve upward to remove.
Remove the bellows adapter ring from inside the bellows. Note the orientation of the bellows adapter ring as it is being removed to ensure that it is properly inserted during reassembly. (If the ring contains grooves, the ring should be oriented so that the grooves are facing downward in the final reassembly.)

16 Cleaning
At the base of the bag arm, locate the retaining ring. Turn the ring counterclockwise until it is no longer threaded. Lift the bag arm from the breathing system block.
To prevent damage, wash each component gently using a recommended cleaning agent (see TABLE on Page 3). Ensure that all surfaces are cleaned. Rinse with clean, hot water, and allow to dry.
Pull out the canister bottom plate upward.
While holding the sides of the breathing system block, firmly separate and slide it away from its mounting arm.
17 Disinfection
18
Use an approved disinfecting agent (see TABLE on Page 3) for all components while adhering to facility policies and procedures.
Connect all components to the breathing system by reassembling all components in the reverse order. Prior to use after cleaning or disinfecting, power up the system and follow the onscreen prompts to perform the leak test and the compliance test.
After all components are completely dry, inspect them for damage before disinfection or re-assembly and functional testing. If disinfecting the components, continue with step 17, otherwise skip to step 18.
All breathing system components (including the absorber canister components) are autoclavable except the PAW gauge, flow sensor, O2 sensor, and bellows. The components can be autoclaved up to a maximum temperature of 134 ºC (273 ºF) for 20 minutes. Please refer to full Operating Instructions Manual for additional details on Autoclaving, Cleaning and Disinfection
