Response to be taken
Check that the flow selector knob or any attached device has not been
left ON. If contents have been depleted then place unit in the empty
cylinder storage area and replace with full one.
If it’s a first time use, then check the pressure gauge and if the gauge
is in the red section immediately contact customer service and
quarantine the unit for investigation by an Air Liquide Healthcare
representative.
DO NOT attempt to clear a blocked nozzle. Immediately contact
customer service and quarantine the unit for investigation by an Air
Liquide Healthcare representative.
View the top of the flow selector knob to ensure the flow setting
is visible through the viewing port. If the number is not clearly visible
then rotate the knob till the required flow is clearly visible and clicks
into place.
Immediately contact customer service and quarantine the unit for
investigation by an Air Liquide Healthcare representative.
Check that the tubing fits firmly over the barbed outlet. If not then
replace the tubing.
View the front of the unit and if the shroud is twisted contact
customer service and quarantine the unit. Obtain another unit for use.
If the unit is required immediately, then twist the shroud back in-line
and use as normal. At the completion of use, contact customer
service and quarantine the unit for investigation by an Air Liquide
Healthcare representative.
Check that the thread is not damaged to either the sleeved outlet or
the device it’s being connected to.
Check that the outer rim of the sleeved outlet has not been
damaged and is circular in shape. Check the hand wheel engages
properly.
If sleeved outlet is damaged then contact customer service and
quarantine the unit for investigation by an Air Liquide Healthcare
representative.
First check to make sure that the flow selector knob has not been left ON.
Do not attempt to stop a leak. Turn the valve OFF and immediately
contact customer service and quarantine the unit for investigation by
an Air Liquide Healthcare representative.
