General instructions for use
All personnel handling cylinders with integrated valves should
be fully trained to carry out each operation and be fully aware
of the requirements detailed in this instruction for use.
Before Use
→ Make sure that the digital display (5) contents indicator shows there is
enough content for intended use.
→ Make sure that the flow selector (3) is set at zero.
→ Connect the delivery device to outlet (1 or 4), see below.
→ Slowly turn the shut-off valve (2) anticlockwise to open the LIV IQ fully.
→ If a delivery device is connected to the flow outlet (4), turn flow
selector (3) stepwise up through flow settings to select flow.
The patient can now be connected to the delivery device.
1) Pressure outlet equipped with
quick-connector (if provided)
Pressure outlet, 1) – additional connection information
If provided, the pressure outlet is equipped with a quick-connector and
allows connection to a medical device. Output pressure 50 psi nominal. The
flow selector does not control the flow from the pressure outlet.
To connect a delivery device to the quick-connector (pressure outlet):
→ Make sure that the probe connector is compatible with the respective
medicinal gas.
→ Insert the probe connector into the quick-connector so that it engages
correctly. Pull on the connector to make sure that it is sitting correctly.
This quick-connector does not have a function to retain the inserted probe.
Therefore, do not disconnect the connector until the valve is closed and
depressurized.
A faulty connection can result in leaks and/or to the ejec-
tion of the connector, with potential injuries/damage.
