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).
• 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 dam-
aged.
• 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 fi tting 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 fi tted with a fl ow-metering device, set the fl ow control
knob on the "ZERO" position - Ensure the fl ow control knob engages
correctly.
• 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 fi re or
explosion arising from oxygen pressure shocks. Insu cient opening of
the cylinder valve could reduce actual fl ow 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)
• fl owmeter (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.
