Regulators IFU GB,FR,DE,NL Rev 03 Page 6/44 12/02/2010
•Visually check possible leakages:
- regulator inlet connection to cylinder valve
- pressure gauge to main body
- pressure relief valve vent hole(s)
- flowmeter (if any)
•Turn off the cylinder valve by turning the hand wheel in an clockwise direction to
stop position. Do not use excessive force.
•If any leakage is detected, use the procedure in chapter 6.3 and return the product
to GCE for service.
•Ensure the flow control knob is on the “ZERO” position.
•Ensure the cylinder valve is open – in the “ON” position.
•Check that the gauge indicates pressure/contents. If the pointer reaches the red
area send the cylinder for the filling
•For regulators fitted with a flowmetering device check that there is gas flow at each
setting (for instance, by listening for the sound of gas flow or checking presence of
bubbles in a humidifier).
•Turn off the shut off cylinder valve by turning the hand wheel in a clockwise direction
to the stop position. Do not use excessive force.
•Reset the flow control knob to on the “ZERO” position once the gas flow stops and
the regulator is vented..
•For regulators fitted with a pressure outlet, ensure it is functional by connecting and
disconnecting a male QC probe.

To be connected to the flow outlet:
Humidifiers, breathing masks or cannulas, gas savers, nebulizers.
To be connected to the pressure outlet:
Flexible hoses, flow meters, Venturi suction ejectors.
•At regulators fitted with pressure outlet together with ejector outlet don´t use
quick coupler and ejector outlet in the same time. Especially when inlet
pressure is bellow 50 bar it may negatively affect performance of the
regulator.
•Before connecting any accessory or medical device to the regulator, always
check that it is fully compatible with the product connection features & the
product performances.
Pressure outlet I
•Ensure the male quick coupler is compatible with the pressure outlet feature.
•Connect the male quick coupler.
•Check if the male quick coupler is fully engaged.
•Regulator with threaded connector as pressure outlet shall be only an integral
part of medical equipment. Do not use it for other purposes!
