6.1.2. Fitting to medical cylinder valve
•
Secure the gas cylinder stand.
Screw connection (bull nose or nut type)
•
Connection equipped with rubber sealing - tighten by hand!
•
Connection equipped with metal to metal sealing or plastic sealing -
tighten by means of a torque wrench (max. tightening torque is 50 Nm).
EN
•
Turn the regulator into the correct position for use and tighten the nut by
hand - do not use tools.
Pin index connection
• Position the pin-index over the cylinder valve with the pin(s) on the pres-
sure regulator pointing towards the cylinder valve connector holes on
the cylinder valve.
•
Press the regulator inlet connection pins into the cylinder valve connec-
tor holes - do not use force, otherwise the pins or holes may be damaged.
•
Tighten the screw on the regulator onto the cylinder valve connector via
the T-bar handle. Do not use tools.
•
Position the equipment so that the regulator user outlets point away
from personnel or patient.
Fitting the regulator with too high a torque to the cylinder valve may re-
sult 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
•
For regulators fitted with a flow-metering device, set the flow control
knob on the "ZERO" position - Ensure the flow control knob engages cor-
rectly.
• Open the cylinder valve slowly by turning the hand wheel in anticlock-
wise direction approx 1 to 1½ 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.
•
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 di-
rection 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.
