•
Visually check if the product or the medical gas cylinder is contaminated; if needed,
for the regulator, use the cleaning procedure detailed in this section (if required for
the cylinder, refer to the gas cylinder manufacturer cleaning recommendation).
•
Check if the product service is due or 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 service or 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.
•
Remove caps from inlet and/or flow outlet. Keep caps in a safe place for reuse
during transport or storage.
•
The product is dedicated only for use with the gas specified on its labelling. Never
try to use for another gas.
Fitting to medical cylinder valve
•
Secure the gas cylinder stand.
Screw connection (bull nose or nut type)
•
Manually screw the bull nose or the nut onto the cylinder valve connector.
•
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 pressure
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 fitting to the cylinder valve, do not apply torque/load to any other parts
of the product.
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 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 fire or
explosion arising from oxygen pressure shocks. Insufficient opening of the
cylinder valve could reduce actual flow delivered.
