SECTION 1—GENERAL GUIDELINES
SECTION 1—GENERAL GUIDELINES
WARNING
GENERAL GUIDELINES contains important information for the safe operation and
use of this product. DO NOT use this product or any available optional equipment
without first completely reading and understanding these instructions and any
additional instructional material such as Owner’s Manuals, Service Manuals or
Instruction Sheets supplied with this product or optional equipment. If you are
unable to understand the Warnings, Cautions or Instructions, contact a healthcare
professional, dealer or technical personnel before attempting to use this equipment
- otherwise, injury or damage may occur.
In order to ensure the safe installation, assembly, and operation of the HomeFill II Compressor, these instructions MUST be followed.
CAUTION
Federal law restricts this device to sale by or on the 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.
Operating Information
The use of this device is limited to the oxygen patient. Cylinders MUST be used only by the oxygen patient and are not to be distributed to any other individual for any purpose.
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.
DO NOT allow oil from your hands or other source to come in contact with the regulator or cylinder valve connection. These solutions may be flammable and cause injury.
The HomeFill II is equipped with a High Pressure Relief Valve to ensure the user’s safety.
When activated, this safety feature will make an extremely loud noise. If this noise occurs,
turn the unit Off. DO NOT use. Service unit before use. Refer to Replacing Burst Disk
Fitting on page 41.
Before moving or repositioning either the compressor or the concentrator, ALWAYS disconnect the AC power cords and the interconnect hose between the compressor and concentrator. Failure to do so may result in damage to the unit or personal injury.
Keep the oxygen tubing, cord, and unit away from heated or hot surfaces, including space heaters, electric blankets, stoves and similar electrical appliances.
