NOTE
z If the concentration cannot be set, do not force the control dial. Check that all other
vaporizers connected are in “0” position and that the interlock device is operational.
z Stop use of the vaporizer if the control dial gets loose or falls off.
During use, check the filling level in the sight glass regularly. The filling level is not visible between
the minimum and maximum marks then do not use the vaporizer. When the vaporizer is empty or
overfilled then the output concentration can be incorrect. When the minimum mark is reached, fill the
vaporizer (see 4.2 Filling the Vaporizer).
1. If the anesthetic agent monitor shows implausible values, check the vaporizer for incorrect
filling and check the monitor for incorrect setting.
NOTE
z During prolonged operation with both a high flow of fresh gas and a high
concentration, the concentration administered may decrease. See 11.8 Influence of
Running Time.
CAUTION
z Jerky movements or tilting at an angle of more than 30°can cause incorrect output
concentration.
z Equip with anesthetic gas scavenging system which complies with ISO80601-2-13 to
purify the air of the operating room.
2. If it is necessary to change to another vaporizer:
(1) Set the vaporizer being used to “0”.
(2) Disconnect the vaporizer being replaced (see 6.4 Disconnecting the Vaporizer).
(3) Switch the anesthetic agent monitor to the new anesthetic agent (If necessary, refer to
the agent monitor instruction for use).
(4) Connect the new vaporizer (see 6.1 Connecting the Vaporizer).
