The plastic tubing supplied with the gas should be pushed firmly
over the reducing connector.
Slowly turn the control knob anti-clockwise until the ball in the flow
indicator is between the two marks. This will then supply a gas flow of
approximately 0.25 l/min. Apply this flow for 25 seconds and then use
the calibration button tool to depress the calibration button.
