A - Inlet stem
The regulator is fitted to the medical cylinder valve and to the pipeline
system by means of an inlet stem. The stem's nut can be female or male
threaded. The inlet stem contains a filter.
B - Inlet pressure gauge
EN
The pressure gauge is designed to indicate cylinder contents (the medical
cylinder shut-off valve must be set to the ON position to allow pressure
measuring).
C - Outlet pressure gauge
The pressure gauge is designed to indicate outlet pressure in the valve
and in the pipeline system.
D - Pressure outlet
The regulator may be fitted with a pressure outlet. The pressure outlet is a
direct outlet from the low-pressure chamber. One type of pressure
outlet is used: The pressure outlet is fitted with a threaded connector.
Regulators with this type of pressure outlet can only be used as an integral
part of a unit of medical equipment (e.g. emergency ventilator, anaesthesia
device, etc.) or in a pipeline system.
E - Pressure relief valve

taminated; if needed, clean the regulator in accordance with the clean-
ing procedure detailed hereinafter, (in case of cylinder contamination,
refer to the gas cylinder manufacturer cleaning recommendations).
• Check whether the relevant product service term or the total life time of
the GCE product and of the gas cylinder have not been exceeded (refer
to date coding system of GCE or of the owner). If the service term or the
life time has been exceeded, remove the regulator (or the gas cylinder)
from service & identify its status appropriately.
• Ensure that the product inlet stem is compatible with the medical cylin-
der valve (gas/ thread type).
• Check the presence & integrity of the inlet stem seals / correct size of
