Remove the protection cap from the inlet and/or flow outlet. Keep the
caps in a safe place for possible reuse during transport or storage. The
product is intended for use only with the gas specified on its label. Never
try to use it for another gas!
Fitting to the medical cylinder valve
• Secure the gas cylinder's position.signs of external damages, remove
them from service and identify their status.
Screw connection (with male or female thread)
• Manually screw the thread onto the cylinder valve connector.
• Turn the regulator into the correct position for use and tighten the nut by
hand - do not use tools.
• Position the equipment in such way so that the regulator user outlets
point away from personnel.
Fitting the regulator to the cylinder valve with too high torque may result
in damage.
When fitting the regulator to the cylinder valve, do not apply torque/ load
to any other parts of the product.
Leakage check before use
• Slowly open the cylinder valve by turning the hand wheel in anticloc
wise direction approx. 1 to 1½ turns.
Sudden opening of the cylinder valve could cause danger of fire or ex-
plosion arising from oxygen pressure shock. Insufficient opening of the
cylinder valve could reduce actual flow delivered.
• Check visually and acoustically for possible leakages on:
• the regulator inlet connection to the cylinder valve,
• the pressure relief valve vent hole(s),
• the pressure gauge connection to the main body,
• Turn o the cylinder valve by turning the hand wheel in a clockwise direc-
tion to the "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.
Functional checks before use
• Ensure that the cylinder valve is open, i.e. in the "ON" position.
• Check that the gauge indicates pressure.
• Turn off the cylinder valve by turning the hand wheel in a clockwise di-
rection to the "stop" position. Do not use excessive force.
• For regulators fitted with a pressure outlet, ensure it is functional by con-
necting and disconnecting an output extension.
