NOTE!
It is recommended to use disposable cartridges filled and sealed at the factory. To do so, remove the
cartridge from the factory packaging and sealed plugs from the fittings. After use, the cartridge must be
marked as «USED» and disposed of as soon as possible.
CAUTION!
Do not fill the cartridge with a used, unsieved, or expired soda lime absorber.
Filling the breathing apparatus with oxygen
The breathing apparatus cylinder must be filled with gaseous oxygen that is suitable for breathing
and has parameters of medical-grade oxygen with a minimum degree of purification of 99.5 %
by volume.
The oxygen pressure in the cylinder must correspond to the values given in the graph below for
different temperatures.

The deviation of pressure from the specified values by no more than 1.0 MPa is permitted
Gas temperature in the cylinder is considered as an equal to the ambient temperature if the
cylinder has been kept at such a temperature for at least 5 hours.
The filling of the cylinder must be carried out with intermediate time lag in two or three stages,
each time the temperature inside the cylinder should equalize with the environment.
NOTE!
For easy and convenient filling of oxygen cylinders,it is recommended to use DEZEGA Oxygen gas
booster system HIHPG2.
Preparation of cooling elements
Use special forms for water ice with lids to freeze water ice cubes.
