SECTION 1—IMPORTANT SAFEGUARDS
Perfecto 2™10 Part No 1148070
SECTION 1—IMPORTANT
SAFEGUARDS
Important Safeguards
In order to ensure the safe installation, assembly and operation of the Perfecto2
concentrator these instructions MUST be followed.
 CAUTION
“Caution: Federal law restricts this device to sale or rental by or on order of a physician,
or any other practitioner licensed by the law of the State in which he/she practices to use
or order the use of this device.”
 DANGER
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 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 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 technician for examination
and repair.
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 12 inches away from walls, draperies or furniture.
Invacare recommends that Crush-Proof oxygen tubing be used with this product and not
exceed 50 ft. (15.2m) in length.
