Before Use - GCE VARIMED S400 Mode D'emploi

B - Inlet pressure indicator or sensor
The regulator is fitted with a pressure indicator or sensor which is intended for
cylinder gas content indication only, not for measuring purposes.
The pressure indicator or sensor can be equipped with output of electric
signal. The connection of pressure indicator or sensor with output of electric
signal must be carried out by trained personnel in accordance with national
regulations pertaining to the electric device and standard EN ISO 7396-1.
Output of electric signal shall be connected only to device which is in
accordance with standard EN ISO 60601-1 and 60601-1-2.
D - Pressure outlet
Pressure regulator is fitted with a pressure outlet. The pressure outlet is the
outlet directly from the low-pressure chamber. Two types of the pressure
outlet can be used:
Pressure outlet I – is fitted with a gas specific medical quick connector also
called „quick coupler". The user can connect another piece of equipment to
this outlet with a gas specific male probe. The quick connector self seals
when the male probe is disconnected. This outlet is for supplying gas at a
controlled pressure to power medical devices, e.g. medical ventilator.
Pressure outlet II – is fitted with a threaded connector. The regulator with this
type of pressure outlet shall be only an integral part of medical equipment
(e.g. emergency ventilators, anaesthesia devices, etc.).
Pressure relief valve
Pressure relief valve serves for reduction of overpressure in the regulator. It is
fitted on the rear part of the regulator body.

6.1. BEFORE USE

6.1.1. Visual inspection before use
Check the product (including product labels and marking) and the the gas
•
cylinder for damage. If damaged, remove it from service and identify its
status suitably.
Visually check if the product or the medical gas cylinder is contaminated;
•
if needed, for the regulator, use the cleaning procedure detailed in this
document (if required for the cylinder, refer to the gas cylinder manufacturer
cleaning recommendation).
• Check if the product service is due or that the total life time of the GCE
product has not been exceeded according to the serial number stamped on
the rear part of the regulator (see section 9). If service or life time has been
exceeded, remove the regulator from service and suitably identify its status.
• Ensure that the product inlet stem is compatible with the medical cylinder
valve (gas/thread type).
• Check the presence & the integrity of inlet stem seals / correct size of seal.
