2 - 18 046-001141-00 A5/A3™ Service Manual
WARNING: The A5/A3 Anesthesia System has a Selectatec mount system which will 
only allow vaporizers to be mounted that have an interlock system 
which prevents more than one vaporizer simultaneously being turned 
on. Do not attempt to override this safety feature.
WARNING: Use care in lifting and manipulating vaporizers during the mounting 
process as their weight may be greater than expected, based on their 
size and shape.
NOTE: The barometric pressure may differ from the calibration pressure of the 
anesthetic vaporizer. This may cause an inaccurate output of the 
anesthetic agent. The operator should continuously monitor the 
concentration of anesthetic agent during system use.

2.2.3.1 Mount the Vaporizer(s)
1. Mount the vaporizer onto the manifold.
2. Push and turn the locking lever clockwise to lock the vaporizer in position.
3. Ensure that the top of the vaporizer is horizontal. If not, remove the vaporizer and reinstall it.
4. When reinstalling the vaporizer, lift each vaporizer straight up off the manifold rather than 
pulling forward. Do not rotate the vaporizer on the manifold.
5. If a vaporizer unintentionally lifts off the manifold, install it again and complete steps 1 through 
3. If the vaporizer lifts off a second time, do not use the system.
NOTE: A Desflurane vaporizer may be mounted similarly as other vaporizers, 
but may require a power cord. For more detailed instructions on 
installation and proper use, refer to the specific manufacturer's 
Instructions for Use of the Desflurane vaporizer.
2.2.3.2 Fill the Vaporizer
NOTE: The A5/A3 should use vaporizers with Selectatec mounting system that 
are compliant to ISO 8835-4. Refer to the vaporizer manufacturer's 
Instructions For Use for filling or draining the vaporizer and other 
information.
