Connecting backup gas cylinders
for O2 and N2O
Even if Julian is connected to a gas supply pipeline,
the cylinders must remain on the workstation as
backup supply.
● On the back of the workstation:
place full tanks ( E-size) in the cylinder holders and
secure in position.
1 Attach pin index pressure reducing adapters onto the
cylinder valves.
2 Screw the gas hoses into the ports on the front of the
gas supply block.
3 Connect pressure sensor cable to the corresponding
sensor port.
● Check cylinder pressures:
4 Slowly open the cylinder displays.
5 Check the pressure displays.
The pressure displays light up when the Julian
workstation is connected to line power.
WARNING !
● Always use extreme caution when handling O2
cylinders!
● Oxygen intensely supports any burning!
No smoking, no open fire in areas where
oxygen is in use!
● Always secure O2 cylinders against tipping!
● Do not expose O2 cylinders to extreme heat!
● Do not use oil or grease on O2 equipment
such as tank valves or pressure regulators.
Do not touch with oily hands. Risk of explo-
sion!
● Open and close valves slowly, with smooth
turns. Do not use any tools.
● If a cylinder valve is leaky or difficult to
operate, it must be repaired by an authorized
professional.
● Max cylinder pressure (O2 and N2 O)
< 19.000 kPa (2750 psi).
