Chapter 1: Introduction
Your health care professional has determined that supplemental oxygen is of benefit to you and has prescribed
an oxygen concentrator set at a specific flow setting to meet your needs. DO NOT change the flow settings
unless your health care professional tells you to do so. Please read and understand this entire manual before
using the device.
Intended Use

therapy. e oxygen from the air is concentrated using a molecular sieve and a pressure swing adsorption
process. Your home care provider will show you how to operate the concentrator and will be available to answer
any questions. If you have additional questions or problems, contact your home care provider.

Warnings and Cautions
Warnings
A warning represents the possibility of harm to the operator or patient.
• For proper operation, your concentrator requires unobstructed ventilation. The ventilation ports are located at the rear
base of the device and at the side air inlet filter. Keep the device at least 15 to 30 cm away from walls, furniture, and
especially curtains that could impede adequate airflow to the device. Do not place the concentrator in a small closed
space (such as a closet).
• Do not remove the covers of this device. Servicing must be referred to an authorized and trained Respironics home
care provider.
• In the event of an equipment alarm or if you are experiencing any signs of discomfort consult your home care provider
and/or your health care professional immediately.
• Oxygen generated by this concentrator is supplemental and should not be considered life supporting or life sustaining.
In certain circumstances oxygen therapy can be hazardous; any user should seek medical advice prior to using this
device.
• Where the prescribing health care professional has determined that an interruption in the supply of oxygen, for any
reason, may have serious consequences to the user, an alternate source of oxygen should be available for immediate use.
• Oxygen vigorously accelerates combustion and should be kept away from heat or open flame. Not suitable for use in
the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxide.
• Do not smoke, allow others to smoke or have open flames near the concentrator when it is in use.
• Do not use oil or grease on the concentrator or its components as these substances, when combined with oxygen, can
greatly increase the potential for a fire hazard and personal injury.
• Do not use the oxygen concentrator if either the plug or power cord is damaged. Do not use extension cords or
electrical adapters.
• Do not attempt to clean the concentrator while it is plugged into an electrical outlet.
• Device operation above or outside of the voltage, LPM, temperature, humidity and/or altitude values specified may
decrease oxygen concentration levels.
• Your home care provider is responsible for performing appropriate preventive maintenance at the intervals
recommended by the device manufacturer.
Cautions
A caution represents the possibility of damage to the equipment.
• Do not place liquids on or near the device.
• If liquid is spilled on the device, turn the power off and unplug from electrical outlet before attempting to clean up
spill. Call your home care provider if device does not continue to work properly.
