Safety instructions 15
• Always wash your hands before starting to work
on the oxygen supply.
• Smoking and open flames are strictly prohibited
in the vicinity of all fittings containing or trans-
porting oxygen.
• During assembly and when changing the oxygen
cylinder, only hand pressure should be used
when tightening the screw connections to the
cylinder and to the pressure reducer.
Never use tools for this purpose. Excessive tighten-
ing damages the screw threads and seals and
can cause leaks.
• Protect oxygen cylinders from accidental falls. If
a cylinder falls, the pressure reducer or the valve
may break off and cause a violent explosion.
Important note • Always open the valve of the oxygen cylinder
slowly to prevent pressure damage to the other
fittings.
• The oxygen cylinder should never be completely
emptied as this may allow moisture-containing
air to enter the cylinder and cause corrosion.
Operation
• Both the patient and the ventilator must be kept
under constant observation during ventilation.
• When connecting the patient valve, please
ensure that the direction of respiratory gas flow
(> patient >) is correct. Make sure that neither
the expiration tube nor the spontaneous breath-
ing tube on the patient valve is blocked or im-
peded in any other way, e.g. by the patient’s
position.
Note • Disposable hose system WM 28110 is intended
to be used only once.
