1.
It is imperative that the O-Two Therapy Flow Controller only be operated in accordance with the
instructions as described in this manual by clinically trained and authorized personnel. Do not use the
Flow Controller for driving any medical equipment.
2.
Using oil, grease or other petroleum-based substances with oxygen and oxygen mixtures may cause
fi re or explosion. Never handle Flow Controllers with oily or greasy hands or gloves. Do not use or store
oxygen equipment near excessive heat or open fl ame.
3.
Make sure that the inlet fi ttings on fl ow controllers are properly mated for the gas intended. Never
attempt to force an incompatible connection or change the connectors. Never interchange fl ow
controllers, hoses, or other equipment with similar equipment intended for use with other gases.
4.
Disconnect the fl ow controller from a pressure source and release all gas from the fl ow controller
after each use.
5.
Do not stand in front of a fl ow controller outlet when opening the pressure source in case foreign
particles are present which could cause a hazardous malfunction of the fl ow controller. Never occlude
the outlet to test for the presence of pressure.
6.
The fl ow controller doesn’t indicate that a fl ow is occurring.
7.
Setting the fl ow-selecting knob between adjacent settings may cause the output fl ow to cease!
8.
Varying inlet pressure outside the specifi ed operating inlet pressure has signifi cant impact on the
accuracy of output therapy fl ow rate!
9.
Presence of outlet resistance may result in decrease of the fl ow rates delivered.
10.
Ambient temperature variations within the specifi ed operating temperature range have no eff ect
on the accuracy of fl ow rate.
11.
Oxygen therapy may be critical treatment. The application of oxygen therapy using this fl ow
controller should be made in strict accordance with the prescription and instructions of a physician.
