•
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!
