5 Identification

Every pressure regulator displays a type plate (7) with the following information:
Manufacturer:
Type designation:
Service pressure:
Gas type:
Serial number (6-digit): XXXXXX
EC conformity mark:
Flow outlets are labelled with the litre capacity in l/min.

6 Operation

Attention: Before connecting the gas cylinder, you must wash your hands.
Do not use hand cream or fatty ointments!
• Connecting the pressure regulator to the cylinder valve
Secure the cylinder so that it cannot fall or tip over. Unscrew the protective cap on the gas cylinder.
Remove the pressure regulator from the packaging. Check first of all:
- Is the seal present on the connection (1) of the pressure regulator?
- Is the connection of the pressure regulator and its counterpart on the cylinder valve free of dirt and
contamination?
The connections on the cylinder valve and on the pressure regulator are standardised and specific to
each gas type. As a result, they cannot be confused. Nevertheless, you must check:
- Does the gas cylinder actually contain the correct gas (label/sticker on cylinder shoulder)?
- Is the pressure regulator designed for this gas (see type plate)?
By means of the screw connection (1), screw the pressure regulator by hand clockwise onto the thread
of the cylinder valve. Screwing on by hand is sufficient to create a gas-tight connection between the
pressure regulator and the cylinder valve.
Do not use any tools!
Pressure gauges (2) must not be used as levers! Never use the pressure gauge to tighten/loosen the
pressure regulator from the cylinder!
• Commissioning
Make certain that the equipment to be connected is suitable for medical purposes, for use with medical
gases and for the pressure range. Make sure that hose fittings and screwed connections are securely
seated and pressure-tight (is the seal present and intact?).
Thin hose lines may be bent if they are not routed carefully. Make sure that they are lying free and that
they cannot be subjected to mechanical stress or crushed!
Open the cylinder valve slowly with at least one turn.
The pressure gauge (2) displays the available pressure in the cylinder in bar.
If the pointer is in the red zone, the supply can only be guaranteed for a limited period. In this case, the
cylinder should be replaced as soon as possible. For information, refer to section , "Duration of Gas
Cylinders".
If the cylinder valve is opened quickly, this can lead to a brief pressure surge which is bled off via the
pressure relief valve (3). The noise created as a result does not indicate a fault. The pressure regulator
is operating normally.
The uncontrolled discharge of oxygen in confined spaces can lead to a risk of fire!
Spontaneous combustion may be caused if high concentrations of gas accumulate in
bedspreads, items of clothing etc!
Make sure that all threaded and hose connections are securely and tightly seated and that
respirator masks, nasal canulas etc. are correctly fitted.
If possible, make patients aware of the potential hazards!
