The output pressure
is beyond 150±5
kPa (22±0.7 psi).
Adjust or replace the
secondary pressure
regulator (refer to 11.1.4).

1. Check whether the gas
supply is sufficient.
The gas supply
pressure is less than
280 kPa (40 psi).
Connect or replace the gas
supply.
2. Check whether any
vaporizer alarm is
generated.
A vaporizer alarm
is generated.
Refer to 7.3.6 to clear the
alarm.
3. Install the electronic
vaporizer in another slot and
try to activate it.
Anesthetic agent is
output normally.
Replace the vaporizer base
valve assembly (refer to
11.4.1).
Anesthetic agent is
not output
normally.
(1) Replace the electronic
vaporizer.
(2) If the problem persists,
replace the vaporizer base
valve assembly (refer to
11.4.1).

Select Setup > Service >
Data Monitors >
Vaporizer to access the data
monitoring screen and check
the drive gas pressure of
Vaporizer 1 (or Vaporizer
2).
The drive gas
pressure is within
150±5 kPa (22±0.7
psi).
Replace the electronic
vaporizer.
The drive gas
pressure is beyond
150±5 kPa (22±0.7
psi).
Adjust or replace the

Connect the AGSS
accessories properly.
Check whether the
hospital's waste gas
scavenging system is
normal.
The hospital's
waste gas
scavenging system
is abnormal.
Properly connect to the
waste gas scavenging
system.
Remove the AGSS
assembly by referring to
8.34 and check whether
the sampling line of the
AGSS sensor falls off.
The sampling line
of the AGSS
sensor falls off.
Reconnect the sampling
line of the AGSS sensor.
The sampling line
of the AGSS
sensor does not
fall off.
(1) Reconnect the AGSS
cable.
(2) If the problem persists,
replace the AGSS
assembly and cable (refer
to 11.1.14).
