    the Inogen One® G3 from an AC or DC external power supply, a properly inserted  

    Inogen One® G3 battery should be maintained in the unit. This procedure will ensure  

    uninterrupted operation and will operate all alarms and alerts in the event of a loss of  

    the external powersupply.

NOTE    The Inogen  One® G3 Battery requires an initial full charge of uninterrupted charging  

    from an empty state using the Inogen One® G3 on the AC power source. Do not run  

    the Inogen One® G3 on battery power until this initial charging has been completed.  

    Once the initial charge is completed, the battery may be used with any amount of  

    charge level.

4.  Connect the Power Supply.

Connect the AC Power plug to the Power Supply. Connect the AC Power Plug to the power source and

connectthe Power Output Plug to the Inogen One® G3. The green LED on the Power Supply will be

illuminated and a beep will sound from the concentrator.
CAUTION Ensure the Power Supply is in a well ventilated location as it relies on air    

    circulation for heat dissipation. The Power Supply may become hot during    

    operation. Make sure the Power Supply cools down before handling.

CAUTION The Power Supply is not water resistant.

CAUTION Do not disassemble the Power Supply. This may lead to component failure    

    and/or safety risk.

CAUTION Do not place anything in the Power Supply port other than the supplied wall    

    cord.Avoid the use of electrical extension cords with the Inogen One® G3. If an  

    extension cord must be used, use an extension cord that has an Underwriters  

    Laboratory (UL) Mark and a minimum wire thickness of 18 gauge. Do not connect any

for at least 10 seconds and reconnect.

NOTE When the Power Supply is disconnected from the AC outlet, also disconnect it from the

concentrator to avoid unnecessary battery discharge.
15

5.   Connect the nasal cannula tubing to the nozzle fitting.  

Nozzle fitting is located on the top of the Inogen One® G3. Use of a single lumen cannula up to 25 feet in

length is recommended to ensure proper breath detection and oxygen delivery. Additional titration may

be needed to ensure proper oxygen delivery when using a particular cannula.

CAUTION To ensure oxygen flow, ensure that the nasal cannula is properly connected to the  

    nozzle fitting and that the tubing is not kinked or pinched in any way.

CAUTION Replace the nasal cannula on a regular basis. Check with your equipment provider or  

    physician to determine how often the cannula should be replaced.
6. Turn on your Inogen One® G3 by pressing the ON/OFF Button.           

A single short beep will sound after the Inogen logo is displayed. “Please Wait” will appear while the

concentrator starts up. The display will indicate the selected flow setting and power condition. Following

a brief start‐up  sequence, a warm up period up to 2 minutes will initiate. During this time

period the oxygen concentration is building to but may not have reached specification. Additional warm

up time may be needed if your Inogen One® G3 has been stored in extremely cold temperatures.

7. Set the Inogen One® G3 Concentratorto the flow rate prescribed by your physician or clinician.

Use the + or – setting buttons to adjust the Inogen One® G3 to the desired setting. The current setting

can be viewed on the display.

8. Position the nasal cannula on your face and breathe through your nose.

The Inogen One® G3 will sense the onset of inhalation and deliver a burst of oxygen at a precise time

when you inhale. The Inogen One® G3 will sense each breath and continue to deliver oxygen in this

manner.  As your breathing rate changes, the Inogen One® G3 will sense these changes and deliver

oxygen only as you need it. At times, if you inhale very quickly between breaths the Inogen One® G3 may

ignore one of the breaths, giving the appearance of a missed breath. This may be normal as the Inogen

One® G3 senses and monitors the changes in your breathing pattern. The Inogen One® G3 will normally

sense the next breath and deliver oxygen accordingly.

A green light will flash each time a breath is detected. Make certain that the nasal cannula is properly

aligned on your face and you are breathing through your nose.

WARNING    If you begin to feel ill or are experiencing discomfort while using this device, consult your

    physician immediately.

CAUTION The Inogen One® G3 is designed to provide a flow of high purity oxygen. An advisory  

    alarm, “Oxygen Low”, will inform you if oxygen concentration drops. If alarm persists,  

    contact your equipment provider.

1.   Connect the DC Power Output plug to the Inogen One G3 concentrator.

2. Connect the DC Power Plug (Cigarette Lighter Adapter) to the power source.
19

3. The plug should insert into the socket without excessive force and securely remain in place. The

Cigarette Lighter Adapter comes with a slide switch pre‐adjusted to the narrow position. This

will fit most automobile cigarette lighter sockets. If the Cigarette Lighter Adapter is loose in the

socket, adjust the switch to the "wide" position.

WARNING Ensure that the automobile power socket is adequately fused for the Inogen One® G3  

    power requirements (minimum 15 Amp). If the power socket cannot support a 15 Amp  

    load, the fuse may blow or the socket may be damaged.

WARNING The tip of the CigaretteAdapter Plug becomes HOT when in use.Do not touch the tip  

    immediately after removal from an auto cigarette lighter socket.

CAUTION Ensure the automobile power socket is clean of cigarette ash and the adapter plug fits  

    properly, otherwise overheating may occur.

CAUTION Do not use the DC power cord with a cigarette plug splitter or with an extension  

    cable. This may cause overheating of the DC power input cable.

CAUTION Do not jump start the automobile with the DC power cord connected to the DC power

source. This may lead to voltage spikes which could shut down and/or damage the DC

power cord.

CAUTION When powering the Inogen One® G3 in an automobile ensure the engine is running.  

    Operating the device without the engine running may drain the car battery.

Traveling By Air The information stated in this section is pending FAA Approval.

The FAA allows the Inogen One® G3 onboard all U.S. aircraft, here are a few points to make air travel easy.

Planning your Flight

When flying with the Inogen One® G3, you must inform the airline that you will be using your Inogen One®

G3 onboard the aircraft. You must also keep a signed statement from your physician with you that

includes:

• Your ability to see/hear alarms and appropriately respond.

• When oxygen use is necessary (all or a portion of the trip).

• Maximum flow rate corresponding to the pressure in the cabin under normal operating conditions.

• A new statement will not be necessary each time you fly, but the statement should be available during

every flight.

• Some airlines may equip their aircraft with onboard electrical power. You may have an opportunity to

request a seat with a power port which can be used to power your Inogen One® G3. However, availability

varies by airline,type of aircraft and class of service. You should check with your airlinesfor availability and

always plan on having sufficient battery power for the duration of your flight, plus a conservative estimate

of unanticipated delays.

• The DC power cord is equipped with a commonly used cigarette lighter adapter. However, aircrafts use

different power port configurations and it is difficult to determine which type of power port compatibility

your aircraft may supply; it’s a good idea to purchase an adapter such as Magellan’s Em Power Socket

Connector Item #EA270. Contact Magellan’s at 800‐962‐4943 or visit www.magellans.com for a store

location near you or purchase options online.

Before your Flight

Here are some things to keep in mind the day your flight departs:

• Ensure your Inogen One® G3 is clean, in good condition and free from damage or other signs of

excessive wear or abuse.

• Bring enough charged batteries with you to power your Inogen One® G3 for the duration of the flight plus

a conservative estimate of unanticipated delays.

• Regional/Commuter airlines do not offer onboardelectricalpower. If your travel plans callfor flights on

regional airlines, you will need sufficient battery power for the duration of the flight, plus a conservative

estimate of unanticipated delays.

CAUTION Airlines may not be equipped to provide backup oxygen.

• Arrive at the airport early. Airport security screening personnel may require extra time to inspect your

Inogen One® G3.

• While waiting to board your flight, you may be able to conserve battery power by using the AC Power

Supply to power your Inogen One® G3 from an electrical outlet in the airport terminal if available.

• You should inform the airline you will be using your Inogen One® G3. Have your physician letter with

you and ready for inspection if requested.
During your Flight

1.   If using airline power port, remove the Battery from the Inogen One® G3 Oxygen Concentrator. Due to

aircraft power limitations, the AC Power Supply cannot be used to charge the Inogen One® G3 Battery when

onboard aircraft.

2. Connect the DC Power Plug for available airline power. Check with airline personnel to ensure

compatibility.

• During taxi, takeoff and landing, stow your Inogen One® G3 under the seat in front of you. Your Inogen

One® G3 will fit upright under most airline seats. However, if it doesn’t fit you may turn it on its side.

• It is not necessary to turn off your Inogen One® G3 during taxi, takeoff and landing if your physician’s

written statement requires you receive oxygen during these periods.

CAUTION A change in altitude (for example, from sea level to mountains) may affect total oxygen  

    available to the patient. The Inogen One® G3 has been verified to provide oxygen to  

    specification up to 10,000 ft (3048 m). Consult your physician before traveling to higher or

    lower altitudes to determine if your flow settings should be changed.

After your Flight

• Remember to recharge additional batteries you may have used prior to your next flight.

Traveling By Bus, Train or Boat

Contact your carrier to find out about power port availability.

6. Cleaning, Care andMaintenance

Cannula Replacement

Your nasal cannula should be replaced on a regular basis. Consult with your physician and/or equipment

provider and/or cannula manufacturer’s instructions for replacement information.  A single lumen cannula

up to 25 feet in length is recommended to ensure proper breath detection and oxygen delivery.

CAUTION Use of a cannula other than a high flow cannula (e.g. Salter 1600Q) may restrict oxygen  

    delivery and/or attachment to nozzle fittings.

Case Cleaning

You may clean the outside case using a cloth dampened with a mild liquid detergent (such as DawnTM) and

water.

WARNING     Do not submerse the Inogen One® G3 or its accessories in water or allow water to enter into

    the case; this may lead to electrical shock and/or damage.

WARNING     Do not use cleaning agents other than those specified in this User Manual. Do not use  

    alcohol, isopropyl alcohol, ethylene chloride or petroleum based cleaners on the cases or on

    the particle filters.
Filter Cleaning and Replacement

The particle filters must be cleaned weekly to ensure the ease of air flow. Remove filter from the front of

the device. Clean the particle filter with a mild liquid detergent (such as DawnTM) and water; rinse in water

and dry before reuse.

NOTE   It may be necessary to clean the particle filters more often in dusty environments.

To purchase additional particle filters contact your equipment provider or Inogen.

Output Filter

The output filter is intended to protect the user from inhalation of small particles in the product gas flow.

The Inogen One® G3 includes an output filter conveniently located behind the removable cannula nozzle

fitting. Inogen requires that this filter be replaced between patients.

The output filter may be replaced by the equipment provider or by the owner using the Output Filter

Replacement Kit (RP‐107).
DC Input Cable Fuse Replacement

The Cigarette Lighter DC Power Plug contains a fuse. If the DC Input Cable is being used with a known good

power source and the concentrator is not operative, the fuse may need to be replaced.

To replace the fuse, follow these instructions and refer to the photograph below.

1.   Remove the tip by unscrewing the retainer. Use a tool if necessary.

2. Remove the retainer, tip and fuse.

3. The spring should remain inside the Cigarette Lighter Adapter housing. If the spring is removed, make

sure to replace the spring first before inserting the replacement fuse.

4. Install a replacement fuse, Inogen RP#125 (BUSS MDA‐12) and reassemble the tip.

Ensure the retainer ring isproperly seated and tightened.
