CONNECT HUMIDIFIER BOTTLE (IF PRESCRIBED)
• Remove cover from humidifier bottle
• Fill humidifier with purified or boiled (and cooled) tap water.
DO NOT
fill past
the maximum water level line.
WARNING: DO NOT
fill humidifier with boiling water
• Tighten the humidifier bottle cover and secure in place by pulling the elastic
band at the front of the device and sliding the humidifier bottle down toward
the humidifier holder.
• Connect the humidifier to the air outlet using humidifier tubing.
• Connect the nasal cannula or oxygen mask tubing to the air outlet of the
humidifier bottle.
• Press the power switch of the oxygen concentrator to the “on” position.
• After assembly, ensure oxygen flow through cannula or mask.
NOTE:
Allow 30 minutes for the device to “warm up” to reach optimum oxygen
concentration. Concentrator may be used during the initial warm up time.
FLOWRATE
• Turn the flowmeter knob to the setting prescribed by your physician.
NOTE:
DO NOT
set the flow above the red
line on the flow-meter. An oxygen flow
greater than 5 L/min will decrease the
oxygen concentration.
NOTE:
If the flow rate on the flowmeter
falls below 0.5 L/min, check tubing or
accessories for blocked or kinked tubing or
a defective humidifier bottle.
