Turn the cylinder away from you and others before opening for 1 second to clear the valve of any debris.
3.ATTACH THE REGULATOR
■ Put the O-ring gasket into the valve on top of the cylinder, if necessary.
■ Make sure that it is marked “Oxygen Regulator.”
■ Check to see that the pin index corresponds to an oxygen cylinder.
■ Secure the regulator on the cylinder by placing the two metal prongs into the valve.
■ Hand tighten the screw until the regulator is snug.
4.OPEN THE CYLINDER AND CHECK PRESSURE
■ Open counterclockwise one full turn and check the pressure gauge.
■ Determine that the cylinder has enough pressure (more than 200 psi). If the pressure is lower than 200 psi, DO NOT use.
5.ATTACH THE DELIVERY DEVICE
■ Attach the plastic tubing between the flowmeter and the delivery device.
Note: When breaking down the oxygen equipment, be sure to bleed the pressure regulator by turning on the flowmeter after the cylinder has been turned off.
