Reinstall the canisters:
a. Ensure seals and rim are free of soda lime dust.
b. Place the canisters in the drain dish.
c. Turn the canister release handle counterclockwise to its locked position while gently applying pressure on the 
canisters to hold them against the canister guides.

Test the Bag circuit for leaks according to the Breathing System tests in the Appendix section of Part 1 of the Operation 
manual.
•Do the test in both the Absorber mode and the Bypass mode.
•Ensure the alarm message “No CO
2 Absorption” activates when in Bypass mode. See “CO2 Bypass mode operation” 
in section 3 of Part 1 of the Operation manual.

Always make sure that the pipeline supply hoses and the breathing circuit 
components are not toxic and will not:
•Cause an allergic reaction in the patient.
•React with the anesthetic gases or agent to produce dangerous 
by-products.
ww w wTo prevent incorrect values or equipment malfunction, use only
Datex-Ohmeda cables, hoses and tubing.
ww w wThis system operates correctly at the electrical interference levels of IEC 
601-1-2. Higher levels can cause nuisance alarms that may stop 
mechanical ventilation.
ww w wTo help prevent false alarms from devices with high-intensity electrical 
fields:
•Keep the electrosurgical leads away from the breathing system and the 
flow and oxygen sensors.
•Do not put the electrosurgical leads on any part of the anesthesia system.
ww w wTo protect the patient when electrosurgical equipment is used:
•Monitor the correct operation of all life support and monitoring equipment.
•Keep backup manual ventilation available in case the electrosurgical 
equipment prevents safe use of the ventilator.
•Do not use conductive masks or hoses.

Canister setup
Each canister holds 1.35 kg of loose absorbent or 1.13 kg of commercially 
packaged (pre-pack) absorbent. Datex-Ohmeda recommends Sodium or Bar-
ium hydroxide based absorbent.

Change absorbent often to prevent the build up of non-metabolic gases 
when the system is not in use. 
Inspect absorbent at the end of a case. During non-use, absorbent can go 
back to the original appearance. Refer to the absorbent labeling for more 
information about color changes.
If the absorbent completely dries out, it may give off CO (carbon monoxide) 
the next time you use it. For safety, replace the absorbent.
Step 1 
Pull the release forward.
Step 2 
Turn the release clockwise.
