WARNING: Compressed gasses are considered Dangerous Goods/Hazardous 
Materials per I.A.T.A (International Air Transport Association). and 
D.O.T. (Department Of Transport) regulations. It is a violation of federal 
and international law to transport dangerous goods without the 
packages being appropriately identified, packed, marked, classified, 
labeled and documented according to D.O.T. and I.A.T.A. regulations. 
Please refer to the applicable I.A.T.A. Dangerous Goods Regulations 
and /or the Code of Federal Regulations 49 (Transportation, Parts 171-
180) for further information.
WARNING: Avoid exposure to respiratory gases by always directing the fresh gas 
flow from the fresh gas outlet to the waste gas scavenger.
WARNING: When using the AG module to perform AG measurements on the 
patients who are receiving or have recently received anesthetic 
agents,connect the outlet to the waste gas disposal system to prevent 
the medical staff from breathing in the anesthetic agents.
WARNING: Remove the airway sampling line from the patient’s airway and seal the 
sample port while nebulized medications are being 
delivered.Nebulized medications interfere with accuracy gas reading.
WARNING: Before connecting the exhaust line to the sample gas outlet on the 
compact airway module,ensure the other end is connected to the 
sample gas return port on the anesthesia machine.Incorrect 
connections may cause patient injury.
WARNING: Perform factory calibration in the working environment after 
completion of anesthesia machine assembling.Contact us if factory 
calibration is required during system use.
WARNING: Do not perform testing or maintenance on A5/A3 anesthesia machine 
while it is being used on a patient.Possible injury can result.
WARNING: Items can be contaminated due to infectious patients.Wear sterile 
rubber gloves.Contamination can spread to you and others.
WARNING: Obey infection control and safety procedures.Used equipment may 
contain blood and body fluids.
Cautions
CAUTION: This device uses high pressure compressed gas. When attaching or 
disconnecting backup gas cylinders, always turn the cylinder valves 
slowly. Use the A5/A3 flow meters to bleed down the pressure, 
watching the cylinder gauge indicate the depleting cylinder pressure, 
before disconnecting the cylinder from the yoke. Always open and 
close cylinder valves fully.
CAUTION: This device operates using compressed gas at high pressures from the 
hospital central supply. When connecting gas supply lines attach the 
hose connection to the machine before connecting the quick 
disconnect fitting to the hospital source. Disconnect the supply hose 
from the hospital source connection prior to disconnecting it from the 
A5/A3 gas connection fittings.
CAUTION: Refer to section 3.3 Periodical Maintenance Schedule for assistance 
when performing scheduled periodic maintenance.
