CAUTION
Before changing the pressurized gas cylinder, its valve must be hand-tightened!
 Drain any residual gas from the pressure regulator via the output until
the pressure gauge on the pressure regulator shows "0".
 Loosen the O
2
NIST screw connector from the O
2
input on the
EVE
TR
.
 Loosen the fastening buckles on the support frame and carefully
remove the oxygen cylinder.
 Remove the pressure regulator from the valve by turning the screw
connector counter-clockwise and connect to the new cylinder.
 Place the new cylinder in the support frame and close the fastening

This completes the cylinder replacement.
CAUTION
After changing the pressurized gas cylinder, a leakage test according to manufacturer
instructions must be carried out.
5.1.4 Connection to the central gas supply
If the device is not operated with an oxygen cylinder, it must be
connected to the CGS. Connect the O
2
hose to the O
2
connector on the
left side of the EVE
TR
device (see chapter 3.3) and to the CGS wall
outlet.
5.1.5 Connecting to an oxygen concentrator
The device can also be operated with an oxygen concentrator.
Connect the O
2
hose to the O
2
quick coupling on the left side of
the EVE
TR
device (see chapter 3.3) and to the oxygen
concentrator in accordance with the manufacturer instructions.
