SAFETY SUMMARY
SAFETY SUMMARY
CAUTION
Caution: Federal law restricts this device to sale by or on
order of a physician, or any other practitioner licensed by
the law of the State in which he practices to use or order
the use of this device.
Risk of electric shock. DO NOT disassemble. Refer servicing
to qualified service personnel.
READ THE FOLLOWING INFORMATION BEFORE
OPERATING THIS PRODUCT.
WARNING
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 pres-
sure. These substances MUST be kept away from the oxygen
concentrator, tubing and connections, and all other oxygen
equipment. DO NOT use any lubricants unless recom-
mended by Invacare.
For optimum performance, Invacare recommends that each
concentrator be on and running for a minimum of 30 min-
utes at a time. Shorter periods of operation may be harmful
for maximum product life. If it has a damaged cord or plug, if it is
not working properly, if it has been dropped or damaged, or
dropped into water, call ualified Service Personnel for examina-
tion and repair.
Keep the cord away from HEATED or HOT surfaces.
NEVER drop or insert any object into any opening.

5
SAFETY SUMMARY
WARNING (CONTINUED)
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
(supplied by Invacare) be used with this product and NOT
exceed 50 ft. (15.2m) in length.
MAINTENANCE
The Invacare Oxygen Concentrator was specifically designed
to minimize routine preventative 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 preventative
maintenance or performance adjustments on the oxygen
concentrator.
RADIO FRE UENCY 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 ELECTROCUTION.
WARNING
ALWAYS unplug this product IMMEDIATELY after using.
Avoid using while bathing. If continuous usage is required by the
physicians prescription:
The concentrator must be located in another room at least
seven (7) feet from the bath.
DO NOT come in contact with the concentrator while wet.
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. UN-
PLUG IMMEDIATELY.

6
TO REDUCE THE RISK OF BURNS, ELECTROCU-
TION, FIRE OR INJURY TO PERSONS.
WARNING
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.
A product should NEVER be left unattended when plugged in.
Close supervision is necessary when this product is used by, on
or near children or bed confined individuals.
Use this product for only intended use as described in this
manual.
DO NOT use parts, accessories or adapters other than those
authorized by Invacare or warranty will be voided.
DO NOT connect the concentrator in parallel or series with
other oxygen concentrators or oxygen therapy devices, or
warranty will be void.
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.

SAFETY SUMMARY
GROUNDING INSTRUCTIONS
A. This product should be grounded. In the event of an
electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the
electrical current. This product is equipped with a
cord having a grounding wire with a grounding plug.
The plug must be plugged into an outlet that is
properly installed and grounded.
DANGER
Improper use of the grounding plug can result in a risk of
electrical shock.
If repair or replacement of the cord or plug is necessary, do
not connect the grounding wire to either flat blade terminal.
The wire with insulation having an outer surface that is green
with or without yellow stripes is the grounding wire. Check
with a qualified electrician or serviceman if the grounding
instructions are not completely understood, or if doubt exists
as to whether the product is properly grounded.
B. This product is for use on a normal 120 V circuit and has a
grounding plug that looks like the plug illustrated in sketch
A shown at the bottom of the page. A temporary adapter,
which looks like the adaptor illustrated in sketches B and
C, may be used to connect this plug to a 2-pole outlet as
shown in sketch C if a properly grounded outlet is not
available. The temporary adaptor should be used only until
a properly grounded outlet (sketch D) can be installed by a
qualified electrician. The green colored rigid ear, lug and
the like extending from the adapter must be connected to
a permanent ground such as properly grounded outlet box
cover. Whenever the adapter is used, it must be held in
place by the screw.
