Instructions for use Zeus Infinity Empowered SW 2.n
Device check
Prerequisites
– The device has been reprocessed, see chapter
"Cleaning, disinfection, and sterilization", and
assembled ready for operation.
– The gas supply, anesthetic gas scavenging sys-
tem and power supply must be connected.
– Optional: Filled backup gas cylinders are con-
nected.
– The emergency ventilation bag, e.g.,
Dräger Resutator 2000, is on the device.
Checking the central gas supply
Check gas pressures:
z All LEDs (A) turn green. The pressure values
are between 2.7 and 6.9 bar.
If gas pressures fall below 2.7 bar, the LEDs go out.
Checking the backup gas cylinders
Immediately change over to cylinder supply in the
event of a central gas supply failure:
1 Open the cylinder valves (A) slowly.
If the pressure is sufficient, all LEDs (B) turn green
(see page 63):
–O
2 greater than 50 bar
– Air greater than 50 bar
–N
2O greater than 30 bar
If the LEDs are not green, the pressure values lie
below the threshold value:
–O
2 less than 20 bar
– Air less than 20 bar
–N
2O less than 30 bar
2 Make sure that the sensor plug and the cable to
the pressure reducer are connected properly.
3 Close the cylinder valves again after the capac-
ity test.
