Symbols Used in Instruction Manual and on Oxygen Concentrator
Refer to this section for an explanation of the symbols and the warnings that accompany them.
"Read Instructions"
This symbol, when used alone or in conjunction with any of the following
symbols, indicates the need to consult the operating instructions provided with the product. A
potential risk exists if the operating instructions are not followed.
"Attention or Caution"
Consult accompanying documents This symbol indicates important
information that requires the user to take special precautions when certain conditions are present.
"No Smoking or Naked Flames"
The use of oxygen therapy requires that special care be taken to
reduce the risk of fire. Materials that burn in air and even some material that will not burn in air
are easily ignited and burn rapidly in high concentrations of oxygen. For safety concerns, all
possible sources of ignition must be kept away from the oxygen concentrator and preferably out of
the room in which it is being used. Smoking in the proximity of an operating oxygen concentrator
is dangerous, and can permanently damage the device and void the warranty.
"Use No Oil or Grease"
Indicates important information about the possibility of spontaneous
and violent ignition that may occur if oil, grease or other petroleum based substances come into
contact with oxygen under pressure.
"Electrical Shock”
Indicates the presence of an electric shock hazard. Warning: To reduce the
risk of electric shock, do not remove cover.
There are no user serviceable parts inside. Refer
servicing to a SeQual dealer or authorized service representative.
"Audible Alarm"
An audible indicator is provided to announce, in a tone distinctly different
from the sounds generated by the oxygen concentrator during normal operation, a reduction in
oxygen concentration, a large unintentional change in flow or when the mains power has been
interrupted.
"Normal Operation"
Green light is on indicating the concentrator is running under normal
operating conditions.
"ON/OFF" (condition)
Push button starts concentrator running.
"Flow Rate Adjustment"
The controlled quantity of oxygen increases or decreases in
increments of 0.5 LPM with each press of the "+" and "-" flow rate adjustment buttons,
respectively.
Warning: The prescribed flow rate setting should only be adjusted under the advice of a
physician.
"Type BF Equipment" F type applied part complying with the specified requirements of IEC
60601-1 to provide a higher degree of protection against electrical shock than provided by type B
applied part.
"Class II Equipment"
Equipment in which protection against electrical shock does not rely on
basic insulation only, but in which additional safety precautions are provided.
"Amperes"
"Alternating Current"
