3Safety Notice
: This unit is not a life-support device, and in certain circumstances oxygen therapy can
be hazardous, it is suggested that if any patient who needs oxygen treatment, please follow
your physician’s advice to choose the right flow and period for oxygen before using the
oxygen concentrator.
: In the event of an alarm, if you observe your oxygen concentrator not working
properly, or if you feel discomfort, consult your Equipment Provider and /or your physician
immediately.
: Use only voltage specified on rating label.
: This device manufactures high concentration oxygen, which promotes rapid burning.
Keep oxygen concentrator at least 5 feet from open flames or sparks.
: Do not smoke while your oxygen concentrator is in operation.
: Do not leave a nasal oxygen cannula under bed coverings or chair cushions.
: Use no lubricants, grease, or petroleum-based products on or near your oxygen
concentrator.
: Electrical shock hazard. Do not remove covers while the unit is plugged in. Only your
Equipment Provider or a qualified service technician should remove the covers or service
the unit.
: Care should be taken to prevent the unit from getting wet or allowing water to enter
the unit.
: The oxygen concentrator should be set to use in an environment without excessive
dust, corruption or toxicological harmful gas.

: Do not place the oxygen concentrator in surroundings where its airflow is obstructed.
: Do not place items on top of the concentrator.
: Always place the concentrator on a hard surface. Never place the concentrator on a
surface such as bed or couch, where the concentrator may tip or fall.
: NEVER leave the concentrator unattended when plugged in.
: Always ensure that both the intake and bottom exhaust vents remain clear of
obstruction. Obstruction of either air intake or exhaust venting during operation can
permanently damage your concentrator.
: It may take up to 5 minutes for the Oxygen Concentrator to reach regular function
and normal performance.
NOTE: If oxygen does not seem to flow, first verify that the flowmeter ball is registering a flow.
Then, place the tip of the cannula into a glass of water; if bubbles come out of the cannula,
oxygen is flowing. If bubbles do not appear, turn off the oxygen concentrator immediately
and refer to Troubleshooting.
NOTE: There is never a danger of depleting the oxygen in a room when you use your
oxygen concentrator.
Radio Frequency Interference
Most electronic equipment is influenced by Radio Frequency Interference (RFI). When
there is strong electromagnetic interference, the LCD may be slightly affected, but the
oxygen concentrator is still running. ALWAYS exercise CAUTION with regard to the use of
portable communications equipment in the area around such equipment.

Environmental Protection
The materials used in the system do not create an environmental hazard. The packing
materials of the system are recyclable, and they must be collected and disposed according
to the related regulation in the country or region where the package of the system or its
accessories is opened. Any material of the system or accessories, that may cause
environmental hazards, must be collected and disposed of in compliance with the local laws
and requirements.
4 Product Introduction
The Cirrus 5 oxygen concentrator is a device that extracts oxygen from atmospheric air. It
uses an electrically-powered molecular sieve to separate nitrogen from ambient air. The
oxygen concentrator can supply a patient with steady oxygen in a safe, reliable, low cost,
adjustable flow.
5 Operation Conditions and Environment
Ambient temperature: 10℃-40℃
Relative humidity: 30%-85%
Air pressure: 700 hPa-1060 hPa
Altitude: Up to 2286m without degradation; consult your equipment provider for further
information regarding to 2286m to 4000m
Do not operate in environments containing corrosive gas and/or a strong magnetic field.
6 Indications for Use:
The 3B Medical Cirrus 5 Oxygen Concentrator is intended to be used by patients with
respiratory disorders who require supplemental oxygen. A high concentration of
supplemental oxygen is supplied and a nasal cannula is used to channel oxygen from the
concentrator to the patient. The Cirrus 5 can be used in a home, institution, vehicle and
various mobile environments.

: Allow for at least 1 foot (12 inches) of clearance away from walls, draperies, furniture,
or other obstructions. Do not place the unit in a confined, non-ventilated area.
: When turned off, allow at least 5 minutes before restarting concentrator.
9.1. If used with a humidifier, ensure only distilled water is used and the humidifier is filled
properly and the lid is secure prior to operation of the concentrator (Fig 3.). Refer to
humidifier’s manufacturer’s guidelines for proper filling, maintenance requirements. Place
the humidifier in the proper location (Fig 4). The humidifier must comply with the general
requirement of the 93/42/EEC European Directive as appropriate.

Flow value:
Cirrus 5：10 position flow value from 0.5 ~ 5L/min on flowmeter as shown in figure. The
maximum recommended flow: 5L/min.
In compliance with the ISO8359 standard, the flow supplied is equal to the flow set on the
flowmeter, accurate to within

10% or 200ml/min, whichever is the larger of the two.
The variation of the maximum recommended flow does not exceed

10% of the indicated
value when a back pressure of 7kPa is applied to the output of the device. The maximum
outlet pressure is 70kPa.
Oxygen Concentration:
-at 2L/min: >90% (+/- 3%)
-at 5L/min: 93% (+/- 3%)
: It is very important to select only the prescribed level of oxygen. Change the flow
selection only under the guidance of your physician.

10 Alarms and Safety Devices
10.1 Alarms
a. Power failure alarm: In case of a loss of main power or when the power cord is not
plugged into the wall outlet, an audible alarm is activated with red indicator on (8.1b on
page 10). The troubleshooting is referred to number 12 on page 19.
b. low/high pressure alarm: There is a pressure sensor on the main board to check the
system pressure, when the pressure is lower than 14 PSI, there is an audible alarm with
yellow indicator (8.1c on page 10). When the pressure is higher than 33 PSI, there is an
audible alarm with red indicator (8.1d on page10). The oxygen concentrator will shut off in
this condition. The troubleshooting is referred to 12 on page 19.
c. Low oxygen concentration alarm (OCSI): The oxygen concentration will rise to the
normal operating level in five minutes of operation. When oxygen purity is

85%, the blue
indicator (8.1e on page 10) will light. If oxygen purity falls below <85%, the red indicator
lamp will illuminate with audible alarm, indicating low purity (8.1f on page10). Refer to the
troubleshooting on page 19. Or call your supplier to service the device
d. Temperature alarm: There is a temperature sensor on the main board to check the
internal temperature, if the internal operating temperature reaches higher than 50°C there
is an audible alarm with red indicator on (see H.T. on the lamp) and the oxygen
concentrator will shut off. The troubleshooting is referred to number 12 on page 19.
10.2 Safety devices
a. Compressor motor:
Thermal safety is ensured by a thermal switch situated in the motor winding (145±5℃).
b. Safety valve:
This is fitted on the compressor outlet and is calibrated to 2.5 bar (250kPa).
