•
Perform visual and audible check for possible leakages:
•
regulator inlet connection to cylinder valve
•
pressure indicator/sensor to regulator body
•
pressure relief valve vent hole(s)
•
flowmeter (if any)
•
Turn off the cylinder valve by turning the hand wheel in an clockwise direc-
tion 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.
6.1.4. FUNCTIONAL CHECKS BEFORE USE
•
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 flow-metering device check that there is gas flow
at each setting (for instance, by listening for the sound of gas flow or check-
ing 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 con-
necting and disconnecting a male QC probe.
6.2. USER OUTLET(S) CONNECTION & USE
6.2.1. LIST OF RECOGNISED ACCESSORIES
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 featu-
res & the product performances.
6.2.2. PRESSURE OUTLET CONNECTION
PRESSURE OUTLET I
•
Ensure the male quick coupler is compatible with the pressure outlet fea-
ture.
•
Connect the male quick coupler.
•
Check if the male quick coupler is fully engaged.
