Caution when handling O
WARNING
Risk of explosion
If the O
cylinder valves or O
2
ing adapters is handled with oily or greasy fin-
gers/hands, the risk of explosion is eminent.
Do not oil or grease the O
pressure reducing adapters, and do not handle
with oily or greasy fingers.
The cylinder valves must be opened/closed slowly
by hand. Do not use tools.
If a cylinder valve is leaky or difficult to operate, it
must be repaired by trained personnel.

WARNING
Risk of supply failure
If pressure reducers not having the required
sensors and measurement features are used
instead of Dräger pressure reducers, reserve
cylinders and their fill levels will not be cov-
ered by alarm and monitoring functionalities
during the power-on self test and operation.
2
Without this monitoring, it cannot be guaran-
teed that, in the event of a loss of the central
supply, the backup functionality of the reserve
gas cylinders will be available. If monitoring
for the remaining capacity of the backup gas
cylinders is not available, the user must take
other equivalent measures.
4 Make sure the second connection to the scav-
enging system is sealed by a screw plug (D).
5 Connect the scavenging connector (C) to the
terminal unit of the anesthetic gas scavenging
system. The terminal unit indicator is green.
6 The AGS is functioning when the float in the
flow tube is between the two marks.
Note the instructions for use of the anesthetic gas
scavenging system AGS.
WARNING
Risk of patient injury
If the side openings of the receiving system are
blocked, negative pressure may result in the
breathing system and the patient's lungs.
Always make sure the side openings of the re-
ceiving system are not blocked.
The anesthetic gas scavenging system may be
connected optionally to the left-hand side of the
workstation.
