ACCESSORIES
There are many different types of humidifiers, oxygen tubing,
cannulas and masks that can be used with this device. You
should contact your local home care provider for
recommendations on which of these devices will be best for
you. They should also give you advice on the proper usage,
maintenance, and cleaning.
The supply accessories (nasal cannula, mask, tubing,
humidifier, etc.) used to deliver oxygen to the patient need to
include a means to reduce the propagation of fire in the
accessories for the safety of the patient and others. If a
commercially available, fire-activated flow stop device is used
in the accessories setup, it should be placed as close to the
patient as practicable.
 ACCESSORIES WARNING
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.

matches, lit cigarettes or other sources of ignition out of
the room in which this product is located and away from
where oxygen is being delivered.
NO SMOKING signs should be prominently displayed.
Textiles and other materials that normally would not
burn are easily ignited and burn with great intensity in
oxygen enriched air. Failure to observe this warning can
result in severe fire, property damage and cause physical
injury or death.

SECTION 1—GENERAL GUIDELINES
Platinum™6 Part No 1141493
SECTION 1—GENERAL GUIDELINES
 WARNING
SECTION 1 - GENERAL GUIDELINES contains
important information for the safe operation and use of
this product.
In order to ensure the safe installation, assembly and operation of
the Platinum concentrator these instructions MUST be followed.
 CAUTION
“Caution: Statutory law can restrict this device to sale by or on order
of a physician, or any other practitioner licensed by the law of the
governmental agency in which he/she practices to use or order the
use of this device.”
 DANGER
Risk of electric shock. DO NOT disassemble. Refer servicing to
qualified service personnel.
 WARNINGS
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, it is necessary that all
sources of ignition be kept away from the product and preferably
out of the room in which it is being used. 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 expressly
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 reduce maximum product life.
If the concentrator has a damaged cord or plug, if it is not working
properly, if it has been dropped or damaged, or dropped into water,
call Qualified Service Personnel for examination and repair.

SECTION 1—GENERAL GUIDELINES
Part No 1141493 7 Platinum™
 WARNINGS
Keep the oxygen tubing, cord, and unit away from heated or hot
surfaces, including space heaters, blankets, stoves and similar
electrical appliances.
DO NOT move or relocate concentrator by pulling on
the 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.
Move oxygen concentrator at least 7.5 cm (3 in) away from walls,
draperies or furniture.
Invacare recommends that Crushproof oxygen tubing (supplied by
Invacare) be used with this product and NOT exceed 15.2 m (50 ft)
in length. Recommended use for Platinum 9 is up to 15.m (50 ft) in
length of high flow tubing.
Maintenance
The Invacare Oxygen Concentrator was specifically designed to
minimize routine preventive maintenance at intervals of once per
year. Only professionals of the healthcare field or persons fully
conversant with this process such as authorized or factory trained
personnel should perform preventive maintenance or performance
adjustments on the oxygen concentrator.
Radio Frequency Interference
Most electronic equipment is influenced by Radio Frequency
Interference (RFI). Caution should be exercised with regard to the
use of portable communications equipment in the area around such
equipment.
To Reduce The Risk Of Burns,
Electrocution, Fire Or Injury To Persons
Avoid using while bathing. If continuous usage is required by the
physician’s prescription:
The concentrator must be located in another room at least2.1 m (7
ft) from the bath.
DO NOT come in contact with the concentrator while wet.

SECTION 1—GENERAL GUIDELINES
Platinum™8 Part No 1141493
 WARNINGS
A product should NEVER be left unattended when plugged in.
DO NOT place or store product where it can drop into water or
other liquid.
DO NOT reach for product that has fallen into water. Unplug
IMMEDIATELY.
This device is to be used only in accordance with the prescription of
a physician and this Owners Manual. If at any time the patient or
attendant conclude that the patient is receiving an insufficient
amount of oxygen, the supplier and/or physician should be
contacted IMMEDIATELY. No adjustments should be made to the
flowrate unless prescribed by a physician.
Close supervision is necessary when this product is used near
children or physically-challenged individuals.
Use this product for only intended use as described in this manual.
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 impair the
performance.
In certain circumstances oxygen therapy can be hazardous.
Invacare recommends that you seek medical advice before using
this machine.
This equipment is to be used as an oxygen supplement and is not
considered life supporting or life sustaining.
Avoid creation of any spark near medical oxygen equipment. This
includes sparks from static electricity created by any type of friction.
Oxygen Concentration
Take care not to set the flow above RED ring. An oxygen flow
greater than 5 L/min (IRC5LXO2AW, IRC5LXAW,
IRC5LXO2AWQ) and 9 L/min (IRC9LXO2AWQ) will decrease the
oxygen concentration.

SECTION 5—OPERATING
INSTRUCTIONS
Intended Use
Your oxygen concentrator is intended for individual use by patients
with respiratory disorders who require supplemental oxygen. The
device is not intended to sustain or support life.
Introduction
Your oxygen concentrator is intended for individual use in the
home. It is an electronically operated device that separates oxygen
from room air. It provides high concentration of oxygen directly to
youthrougha nasalcannula. Clinical studies havedocumented that
oxygen concentrators are therapeutically equivalent to other types
of oxygen delivery systems.
Your provider will show you how to use your oxygen concentrator.
He/She should be contacted with any questions or problems
regarding your oxygen concentrator. This owner’s manual will tell
you about your concentrator and will serve as a reference as you use
your concentrator.
Select a Location
You may select a room in your house where using your oxygen
concentrator would be most convenient. Your concentrator can be
easily rolled from room to room on its casters.
Your oxygen concentrator will perform best when operated under
the following conditions. Usage in environments other than those
described may result in the need for increased equipment
maintenance. The air intake of the unit should be located in a well
ventilated area to avoid airborne pollutants and/or fumes.
Recommended Guidelines for Optimum
Performance
