MILLENNIUM SERVICE & TECHNICAL INFORMATION
INTRODUCTION
This section provides an introduction to the Millennium Oxygen Concentrator devices as well as contact and
service training information.
MILLENNIUM OXYGEN CONCENTRATOR OVERVIEW
The Millennium Oxygen Concentrator is intended to provide supplemental oxygen to persons requiring low flow
oxygen therapy. This device is not intended to be life supporting nor life sustaining. The Millennium Oxygen
Concentrator produces concentrated oxygen from room air for delivery to a patient. The oxygen from the air is
concentrated using a molecular sieve and a pressure swing adsorption process.
TYPES OF CONCENTRATORS
MILLENNIUM H600/H605 CONCENTRATORS
The Millennium H600/605 Concentrators are equipped with a green cabinet and a fluted Base Cabinet.
MILLENNIUM M600/M605/M10600/M10605 CONCENTRATORS
The Millennium M600/M605/M10600/M10605 Concentrators comes equipped with a grey cabinet, a black
Base Cabinet, and the Hour Meter is located in the Base Cabinet.
MILLENNIUM ENHANCED M600/M605/M10600/M10605 CONCENTRATORS
The Millennium Enhanced M600/M605/M10600/M10605 Concentrators comes equipped with a grey cabinet, a
black Base Cabinet, and the Hour Meter is located on the front panel of the Front Cabinet.
CAUTION
U.S. federal law restricts this device to sale by or on the order of a physician.

MILLENNIUM SERVICE & TECHNICAL INFORMATION
SERVICE NOTICE
The Millennium is designed so that trained Service Technicians can perform repair and testing procedures. The
information provided in this manual will allow service technicians to perform the service and maintenance
required on the Millennium. The individual(s) using this manual should have prior training or experience
servicing oxygen concentrators.
SERVICE TRAINING
Respironics offers service training for the Millennium Concentrators. Training includes complete disassembly
of the device, troubleshooting subassemblies and components, and performance testing. For more

WARNINGS & CAUTIONS - PAGE 11041847, REV. 00
MILLENNIUM SERVICE & TECHNICAL INFORMATION
WARNINGS & CAUTIONS
SECTION OVERVIEW
Warnings and Cautions, are used throughout this manual to identify possible safety hazards, conditions that
may result in equipment or property damage, and important information that must be considered when
performing service and testing procedures on the Millennium Oxygen Concentrators.
Please read this section carefully before servicing the Millennium Oxygen Concentrators.
WARNINGS
WARNING
Warnings indicate the possibility of injury to the patient, operator, or technician.
CAUTION
Cautions indicate the possibility of damage to the device
NOTE
Notes are used to emphasize a characteristic or important consideration.
WARNINGS
•Oxygen generated by this concentrator is supplemental and should not be considered life
supporting or life sustaining. In certain circumstances, oxygen therapy can be hazardous; any
user should seek medical advice prior to using this device.
•Where the prescribing physician has determined that an interruption in the supply of oxygen, for
any reason, may have serious consequences to the user, an alternate source of oxygen should
be available for immediate use.
•Keep the unit away from heat and/or open flame as oxygen greatly accelerates combustion.
•Do not smoke when the concentrator is operating or patient is using the oxygen.
•Do not use greases, oils, or any petroleum based solvent or cleaner on or near the unit.
•Use extreme caution when handling the Compressor Capacitor as it holds an electrical charge
until it is properly discharged.
•Avoid handling the molecular sieve material. Respironics recommends the return of the Sieve
Canister Assembly to Respironics for any service that involves sieve disposal.
•Never modify the Power Cord or use adapters, extension cords, etc. The unit is double insulated
and uses a 2-prong not a 3-prong Power Cord. Any modification to the Power Cord could alter
the safety feature.

1041847, REV. 00PAGE 2 - WARNINGS & CAUTIONS
MILLENNIUM SERVICE & TECHNICAL INFORMATION
CAUTIONS
NOTES
WARNINGS (CONT’D)
•A physician must prescribe use of a humidifier with the Millennium. Use of only bubble type
humidifiers is recommended and connections must be secure and free of leaks.
•If the Millennium Oxygen Concentrator has been subjected to hot or cold temperatures for an
extended period of time, it should be allowed to warm up to the stated operating temperatures
before power up. Failure to do so could result in improper performance and or alarm conditions
until the unit reaches normal operating temperatures.
•Do not turn on the unit while any filter is wet or moist.
CAUTIONS
•U.S. federal law restricts this device to sale by or on the order of a physician.
•Place the unit where cooling airflow is unrestricted. Be sure to inform the user not to position the
unit close to drapery or curtains that might restrict the airflow.
•When using a liquid leak detector, be careful not to allow it to contact electrical parts.
•Make sure connections of fittings, tubing, and hoses are secure.
•Be cautious when using thread sealants because they can cause extensive damage to the
internal parts of the unit if allowed within tubing or fittings.
•Device operation above or outside of the Voltage, LPM, Temperature, Humidity and /or Altitude
values specified in the manual may decrease oxygen concentration levels.
•Clean all exterior cabinet surfaces periodically by wiping with a damp cloth, using a mild detergent
and/or hospital disinfectant.
•If the 25-foot tubing, connector, and high flow cannula supplied with the Millennium M10 Oxygen
Concentrator are not used, 10 LPM of oxygen flow may not be achieved.
•Use only Respironics or factory-authorized replacement parts and accessories.
NOTES
•Make sure the Flow Meter is set at the patient’s prescribed flow rate once patient circuitry is
attached.
•Make sure there are no kinks in the user’s oxygen tubing. If necessary, use a non-kink style
delivery tube (unit will go into an audible and visual alarm if the tubing is kinked or the flowmeter is
turned completely off).
