The product is intended only for use with the gas specified on the product.
Never use it for other gas.
6.1.2. Connection to medical cylinder valve
•
Secure the gas cylinder in safe position.
Screw connection (with male or female thread)
Screw the thread into the cylinder valve connector.
•
Turn the regulator into correct position for use and tighten the nut. If the
•
EN
connector has an o-ring, do not use tools.
•
Position the cylinder with the pressure regulator so that the regulator user
outlets do not face personnel.
Fitting the regulator with too high tightening torque to the cylinder valve
may result in damage.
During fitting to the cylinder valve, do not apply torque/load to any other
parts of the product.
6.1.3. Leakage check before use
•
Open the cylinder valve slowly by turning the hand wheel in anticlockwise
direction approx. 1 to 1.5 turns.
Sudden opening of the cylinder valve could result in a danger of fire or
explosion arising from oxygen pressure shocks. Insufficient opening of the
cylinder valve could reduce actual flow delivered.
Visually and by listening check possible leakages on:
•
regulator inlet connection to cylinder valve,
•
•
pressure indicator/sensor to regulator body,
•
pressure relief valve vent holes.
Turn off the cylinder valve by turning the hand wheel in 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 for service.
6.1.4. Functional test before use
Open the cylinder valve – position "ON".
•
•
Check that the pressure gauge indicates pressure.
•
Turn off the cylinder shut-off valve. Do not use excessive force.
To test the regulator functionality, check gas flow through the regulator.
•
For regulators with a quick coupler outlet, connect and disconnect the
male QC probe. For regulators with threaded outlet, gas flows already in
opening the cylinder valve.
