5 Marking

Every pressure regulator displays a type plate (9) with the following information:
Type designation:
Service pressure:
Gas type:
Item/Type number:
Serial number (6-digit):
Date of manufacture:
EC conformity mark:
Manufacturer with address:
The handwheel is labelled with the flow levels in l/min.
Pressure outlets are marked "5 bar".

6 Operation

Oxygen armatures must be kept free of grease. Wash your hands before you
handle the regulator. 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. In the case of laughing gas or carbon dioxide keep in
mind that the cylinder has to stand upright! 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 connector (1) of the pressure regulator?
- Is the connector of the pressure regulator and its counterpart on the cylinder valve free of dirt and
contamination?
The connectors at the cylinder valve and at 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 or 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 safely fixed
and pressure-tight (is the sealing 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!
CAUTION: Every time you open the cylinder valve, check the proper connection between the valve
and the regulator first.
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.
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 closed rooms can lead to a risk of fire!
Spontaneous combustion may be caused if high concentrations of gas accumulate in
beddings, items of clothing etc!
Make sure that all threaded and hose connections are securely and tightly seated and that
respirator masks, nasal cannulas etc. are fitted correctly.
If possible, make patients aware of the potential hazards!
