• Keep the vaporizer upright at all times.
• Never tilt a calibrated vaporizer beyond 45 degrees when charged.
Dangerous overdose may result during subsequent use. This
condition can be detected by calibration verification only.
• Do not connect the vaporizer directly into the patient breathing
circuit.
• Do not turn on two vaporizers at the same time.
• Do not put water or any other solvent in a vaporizer.
• Due to the wick's capacity to absorb agent, the vaporizer will
continue to deliver the set concentration for a considerable period of
time even if no liquid level can be viewed through the sight window.
However, do not use a vaporizer in this condition on a subject.
• Flush flows through an open vaporizer may result in unwanted
concentrations of anesthetic agent.
• Do not ignore maintenance of your vaporizer. An annual calibration
recertification is highly recommended by the manufacturer.
CAUTIONS
• Personnel operating this compact anesthesia system must be
thoroughly familiar with the instruction manual and equipment
operation prior to use with subjects.
• Tampering with the anesthesia system components by unauthorized

b. the flow of oxygen does not immediately stop flowing from the
common outlet after the oxygen flush button is released.
