contact a healthcare professional, dealer or technical personnel before attempting
to use this equipment - otherwise, injury or damage may occur.
Important Safeguards
The use of oxygen therapy requires that special care be taken to reduce the risk of fire. Any
materials that will burn in air, and some that will not, are easily ignited and burn rapidly
in high concentrations of oxygen. For safety concerns, keep all sources of ignition out of
the room in which this product is located and away from areas where oxygen is being
delivered. Textiles, oil and other combustibles are easily ignited and will burn with great
intensity in oxygen-enriched air. NO SMOKING signs should be prominently displayed.
A spontaneous and violent ignition may occur if oil, grease or greasy substances come in
contact with oxygen under pressure. These substances MUST be kept away from the
oxygen concentrator, tubing and connections, and all other oxygen equipment. DO NOT
use any lubricants unless recommended by Invacare.
For optimum performance, Invacare recommends that each concentrator be on and
running for a minimum of 30 minutes at a time. Shorter periods of operation may be
harmful for maximum product life.
Keep the oxygen tubing, cord, and unit away from heated or hot surfaces, including space
heaters, electric blankets, stoves and similar electrical appliances.
DO NOT move or relocate concentrator by pulling on the power cord.
NEVER drop or insert any object into any opening.
NEVER block the air openings of the product or place it on a soft surface, such as a bed
or couch, where the air opening may be blocked. Keep the openings free from lint, hair
and the like.
Fill humidifier with water to the level shown by the manufacturer. DO NOT overfill.
Invacare recommends that Crush-Proof oxygen tubing be used with this product and
NOT exceed 50 ft. (15.2m) in length. Recommended use for Platinum 10 is up to 50 ft. in
length of high flow tubing.
SECTION 1—IMPORTANT SAFEGUARDS

DO NOT place or store product where it can drop into water or other liquids.
DO NOT reach for product that has fallen into water. Unplug IMMEDIATELY.
No adjustments should be made to the flowrate unless prescribed by a physician
therapist.
The product should NEVER be left unattended when it is plugged in.
Close supervision is necessary when this product is used by, on or near children or
physically challenged individuals.
The Platinum concentrator is intended to be used only as an oxygen supplement as
described in the Owner's Manual.
Invacare products are specifically designed and manufactured for use in conjunction with
Invacare accessories. Accessories designed by other manufacturers have not been tested
by Invacare and are not recommended for use with Invacare products.
DO NOT connect the concentrator in parallel or series with other oxygen concentrators or
oxygen therapy devices.
Use of some administration accessories or certain humidifiers not specified for use with
oxygen concentrator may impact the performance.
Avoid creation of any spark near medical oxygen equipment. This includes sparks from
static electricity created by any type of friction.
SECTION 2—INSTALLATION/SEQUENCE OF OPERATION
Part No 1110538 13 Platinum™Series
SECTION 2—INSTALLATION/
SEQUENCE OF OPERATION
Installation/Verification of Battery Free Power Loss
Alarm
When your new Platinum concentrator arrives, it should be checked for proper operating
conditions.
1. If the unit has been in below-freezing temperatures, allow it to warm up to room
temperature before operating.
2. The concentrator may need to be turned on for four to five seconds to charge the
Battery Free Power Loss Alarm. Connect power cord to outlet and turn the
concentrator on. Turn flow control knob counterclockwise and flow will begin
IMMEDIATELY. Set flow rate to five L/min. Let the unit run for 30 minutes, then turn
unit off.
3. Unplug the power cord and press on/off ( ) switch to the On ( ) position. An
intermittent audible alarm will sound. This confirms proper operation of the Battery
Free Power Loss Alarm. Turn On/Off switch Off ( ).
4. Connect power cord to outlet and turn on concentrator. Unit will beep on start-up.
5. Check the oxygen concentration per specifications after 30-40 minutes running time.
Sequence of Operation
Turning on (I) the power switch applies 120 VAC to the compressor motor, hour meter,
transformer, cooling fan and the printed circuit (P.C.) board.
Room air enters the compressor via the cabinet filter and the compressor inlet filter. The
air is compressed by the wobble pistons in the compressor to a pressure of 21 p.s.i. (144.79
kPa) for Platinum 5, XL and 25 p.s.i. (172.36 kPa) for Platinum 10.
As increased pressure creates increased temperature, a heat exchanger is used to lower
the temperature before the air enters the 4-way valve. It is then channeled to a sieve bed
containing the adsorption material. Restriction downstream of the sieve bed causes
pressure to build up inside the sieve bed which is necessary for the adsorption process. A
small amount of relatively pure oxygen enters the top of the second bed through a
restrictive leak in the pressure equalization (P.E.) valve with the balance entering a storage
tank. The nitrogen removed is exhausted back from the bed through the 4-way valve into
room air. A muffler is located at the exhaust end of the valve to muffle the sound of the
exhaust as it exits the concentrator.
The oxygen not being used to exhaust is channeled into the storage tank. The pressurized
oxygen is regulated down to five p.s.i. (34.4 kPa), enters an accurate flow-measuring
device, flows through Outlet HEPA filter and check valve, then out to the patient.
I/O
I
/
O
SECTION 2—INSTALLATION/SEQUENCE OF OPERATION
Platinum™Series 14 Part No 1110538
The electrical activation of the 4-way Valve is accomplished every 8 to 15 seconds by the
pressure sensor and P.C. Board electronics when the pressure reaches a set point of 21
p.s.i. (144.79 kPa) for Platinum 5 and XL; 25 p.s.i. (172.36) for Platinum 10. The time
between cycles is dependent on altitude, flow rate and internal environmental factors.
A P.E. valve opens just prior to the shift of the 4-way valve. This allows highly
concentrated oxygen to enter the just exhausted bed from the top. This additional
pressure allows the bed to start its cycle at a higher pressure. The P.E. valve will close just
after the shift of the 4-way valve.
If main power is lost, the Battery Free Power Loss Alarm will sound a short "BEEP", with
a long pause after. All units are equipped with a diagnostic alarm system that signals if
the pneumatic pressure or electrical systems malfunction. The Troubleshooting Guide in
this manual explains the alarm system signals and reasons, in detail, for your
convenience.
SensO
2
Oxygen Sensor Technology - Ceramic Zirconia
Sensor
Technical Description
The oxygen being produced by the concentrator flows out of the product tank and into
the flowmeter. A small flow of oxygen produced by the unit is sent through a precision
orifice to the oxygen sensor mounted on the printed circuit board.
As the oxygen enters the sensor, it passes through a screen and contacts the sensing disk.
Electric current flowing through a metal film resistor heats the disk in excess of 300°
C.
Oxygen molecules contact the electrode of the disk and pick-up extra electrons to become
oxygen ions. These oxygen ions are attracted to the electrode on the bottom of the zirconia
sensing disk. Because of the crystal structure of the zirconia, only oxygen ions can pass
through. When the oxygen ions reach the bottom electrode, the extra electrons are
released from the oxygen ions and oxygen molecules return to the air. The number of
electrons is directly related to the oxygen concentration. The electrons travel to the P.C.
board where they are counted and the oxygen concentration reading is calculated.
A microprocessor on the P.C. board contains software that interprets the signal being
received from the sensor. It compares the signal to clinically acceptable limits. Signals
outside of the clinically acceptable limits generate responses in the form of lights, audible
indicators, and/or system shut-down.
Operating Sequence
Once the power switch has been turned on ( ), the SensO
2
circuit will wait five minutes
for the concentrator to begin producing clinically acceptable oxygen and the oxygen
sensor to stabilize. The GREEN light will illuminate (indicating normal system operation)
while the oxygen sensor is warming up.
I
/
SECTION 2—INSTALLATION/SEQUENCE OF OPERATION
Part No 1110538 15 Platinum™Series
After five minutes, if the oxygen purity exceeds 85% ± 2%, the GREEN light will continue
to illuminate.
If the oxygen level is not above 85% ± 2% after the first five minutes, the system will
continue to monitor the O
2
and wait for a maximum of 30 minutes from start-up to reach
85% ± 2% before activating an alarm. Environmental factors such as low voltage, high
altitude, or age of the machine will affect the time required to reach 85% ± 2%.
If the oxygen level is not above 85% ± 2% within the first 30 minutes, the oxygen
concentration alarm sequence will activate and the unit will shut down.
When oxygen concentration is above 85% ± 2%, the sensor measures oxygen purity every
10 minutes. If a reading falls below 85% ± 2%, a YELLOW light will illuminate. If the
oxygen purity falls below 73% ± 3% the RED light/Alarm/Shut-Down mode will activate.
