- Oxygen may only be added for the product

variant TNI

20s oxy.

- The oxygen flow meter at the connection

unit may only be operated in an upright ver-

tical position (see Chapter 4.1 Assembling

and setting up the TNI

device)

- Before you fasten the applicator to the

patient, first set the prescribed air-oxygen

mixture at the setting valves of the connec-

tion unit.

- Check the oxygen flow value at regular

intervals.

- Determine the exact oxygen concentration

in the air-oxygen mixture with an indepen-

dent measuring device.

Fire hazard when using oxygen!

IMPORTANT!

WARNING!

- Check before opening the setting valve

whether the float is on

the floor of the metering tube.

- Set the desired amount of oxygen at the oxygen flow meter by

turning the knob at the setting valve

as follows:

increase oxygen flow:

turn knob counterclockwise

decrease oxygen flow:

turn knob clockwise

4 Startup

- The current oxygen flow value is determined

by the float (ball) in a metering tube. Read the

value on the upper edge of the float.

- Note that a maximum oxygen flow of 16 l/min

may be set on the oxygen flow meter.
