4.2 Calibration Warnings, Precautions, and Notes
4.2.1 Warnings
WARNING: For continued protection against fire hazard, replace all fuses with the 
specified type and rating.
WARNING: In order to prevent an electric shock, the machine (protection class I) 
may only be connected to a correctly grounded mains connection 
(socket outlet with grounding contact).
WARNING: Remove all accessory equipment from the shelf before moving the 
anesthesia machine over bumps or on any inclined surface. Heavy top 
loading can cause the machine to tip over causing injury.
WARNING: Possible explosion hazard. Do not operate machine near flammable 
anesthetic agents or other flammable substances. Do not use 
flammable anesthetic agents (i.e., ether or cyclopropane.)
WARNING: The use of anti-static or electrically conductive respiration tubes, when 
utilizing high frequency electric surgery equipment, may cause burns 
and is therefore not recommended in any application of this machine.
WARNING: Possible electric shock hazard. The machine may only be opened by 
authorized service personnel.
WARNING: Compressed gasses are considered Dangerous Goods/Hazardous 
Materials per I.A.T.A. and D.O.T. regulations. It is a violation of federal 
and international law to offer any package or over pack of dangerous 
goods for transportation without the package 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

4.2.2 Cautions
CAUTION: Refer to the ‘‘Periodical Maintenance Schedule’’ on page 3-2 for 
assistance when performing scheduled periodic maintenance.
CAUTION: Do not leave gas cylinder valves open if the pipeline supply is in use 
and the system master switch is turned to 'ON'. If used simultaneously, 
cylinder supplies could be depleted, leaving an insufficient reserve 
supply in the event of pipeline failure.
CAUTION: Use cleaning agent sparingly. Excess fluid could enter the machine, 
causing damage.
CAUTION: This machine must only be operated by trained, skilled medical staff.
4.2.3 Notes
NOTE: Only bacterial filters with a low flow resistance must be connected to 
the patient module and/or the patient connection.
