Operation
3 Only one vaporizer connected at a time. If not:
 Check that there is an Interlock system on
the vaporizer and anesthesia workstation,
and that it is of same type. For differentiating
features, see page 54.
4 Fresh-gas flow must be switched off.
Checking each connected vaporizer:
5 Set the vaporizer to any desired concentration.
6 All other vaporizers must be switched off,
locked, and impossible to switch on.
7 If there is a vaporizer recognition system
present, check that the correct anesthetic agent
is indicated and that it matches the connected
vaporizer.
8 Switch off the vaporizer – the control dial is
engaged in the
0 position.
9 Check that the vaporizer, connector, and fresh-
gas lines are leak-tight (see the instructions for
use of the anesthesia workstation):
– at control dial setting 0 or T
– at control dial setting ≥ 2 Vol% .
10 Flush the breathing system with fresh gas
before connecting a patient.
WARNING
A malfunction in the Interlock system can en-
danger the patient by overdosing or mixing
anesthetic agents.
The tabs in the two openings in the control
dial cap on the Interlock 2 must be undam-
aged. See also the chapter "Checking opera-
tional readiness" on page 54 for more infor-
mation.
On the Interlock S the side pins, which are ex-
tended when a vaporizer is switched on, must
align axially. On the vaporizers, these pins
must be next to each other and never above
each other.
WARNING
Risk of patient injury
The vaporizer will be set to incorrect concen-
tration values.
If the vaporizer recognition does not indicate
the same anesthetic agent as that for which
the vaporizer is calibrated, incorrect concen-
tration values will be indicated.
Check that the correct anesthetic agent is in-
dicated and that it matches the vaporizer con-
nected.
WARNING
Do not operate the vaporizer if the checks
were not successfully completed. Repair by
specialized service personnel.
