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.

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.

WARNINGS & CAUTIONS - PAGE 11041847, REV. 00

MILLENNIUM SERVICE & TECHNICAL INFORMATION

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).

THEORY OF OPERATION

SECTION OVERVIEW

This section describes the theory of operation for the Millennium Oxygen Concentrators.

H600/605; M600/605; ENHANCED M600/605 CONCENTRATOR PNEUMATIC

PERATION

Room air enters through a foam air inlet filter (1) mounted on the side of the cabinet. The primary system air is drawn through the inlet pre-filter, (2) the inlet filter (3) and then through the felt filter (4) by the Compressor (5). The exhaust air then passes through the In-line Muffler (6) to the supply chamber.

The Compressor exhaust air is cooled by the supply chamber (7) and distributed using a pneumatic Valve/ Solenoid Assembly (8). At start up, valve (8) is de-energized allowing compressed air to flow into both Sieve Canisters (9) until the pressure sensor builds up to switching pressure. At switching pressure, a 12 volt signal is received at Valve/Solenoid(8a) closing the input and allowing compressed air to continue through sieve bed (9a) for 6.25 seconds absorbing the Nitrogen and allowing the Oxygen to flow through check valve (10a) and into the product tank (11).

At 5 liters of flow approximately 1/3 of the Oxygen is deposited into the product tank and 2/3 is passed through orifice (12) in to sieve bed (9b) to purge the Nitrogen from the sieve bed, which exits through the exhaust port of the Valve/Solenoid(8b) to exhaust chamber (14) through Blow Down Muffler (15) to outside air in a time of

6.25 seconds.

At the end of this cycle the unit will balance for 1 second which de-energizes valve / solenoid (8b) and allows compressed air to flow into both Sieve Canisters. The pressure reaches the max switching pressure and sends a 12 volt signal to valve / solenoid (8b) and the adsorption cycle starts over in the Sieve Canister (9b). Oxygen is in a continuous flow from the product can (11) through the regulator (16) through the Flow Meter (17) to the bacteria filter (18) to the patient.

H600/605 CONCENTRATOR REPAIR & REPLACEMENT

SECTION OVERVIEW

This chapter illustrates the repair and replacement procedures for the components of the H600/605 Millennium Oxygen Concentrators. Once repair is complete refer to the testing section for proper testing procedures.

WARNINGS

• To prevent electrical shock, disconnect the electrical supply before attempting to make any

device repairs to the Millennium Oxygen Concentrators.

• Use extreme caution when handling the Compressor/motor assembly Capacitor. The Capacitor

can hold a substantial 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 material disposal.

• Even with the unit disconnected from the electrical supply, the Capacitor may still hold an

electrical charge strong enough to cause serious bodily injury. DO NOT touch the Capacitor terminals simultaneously until the Capacitor has been completely discharged. Discharge the Capacitor by shorting the two posts with an insulated screw driver.

CAUTION

• Electronic components used in this unit are subject to damage from static electricity. Repairs

made to this unit must be performed only in an antistatic, ESD-protected environment.

• During all repair and replacement procedures, assure that any connections that are broken

during the process (fittings, tubing, and hoses) are reconnected securely.

• When using leak detector, be careful that it does not come in contact with any electrical

components.

• The fuse on the power control board must be replaced with a fuse of the same rating as the

original. Failure to do so will result in damage to the unit.
