• Check that the total life time of the product and the gas cylinder has not
been exceeded, (refer to GCE or owner's date coding system). If life time
has been exceeded, remove the product (or the gas cylinder) from service
& suitably identify its status.
• Ensure that the product inlet stem is compatible with the medical cylinder
valve (gas/ thread type).
• Check the presence & the integrity of inlet stem seals / correct size of seal.
EN
Always make sure the inlet stem o-ring is in good status, without damage.
Remove caps from inlet and/or fl ow outlet. Keep caps in a safe place for
reuse during transport or storage.
The product is dedicated only for use with the gas specifi ed on its label-
ling. Never try to use for another gas.
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 connector
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 result
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 anticlockwise
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.
