Features

This equipment adopts safe and reliable PSA oxygen production technology. It uses air as the raw material and electric energy as the sole energy source, separating oxygen and nitrogen through multiple filtration and molecular sieve adsorption. This purely physical method ensures stable, safe, and reliable oxygen production. The battery is separate from the main unit, allowing for easy replacement with higher capacity or smaller volume batteries, making it convenient for use on the go.

Safety Precautions

1. This oxygen enrichment machine is intended for health preservation and improving quality of life, not for medical treatment or life extension.
2. Do not use the device without reading and understanding the manual to prevent injury or product damage from improper operation.
3. Oxygen is a combustion-supporting gas. Do not smoke, light candles, or use other open flames while using this device.
4. When the battery is not in use, protect the battery interface and the device's battery interface. Avoid touching conductors or terminals directly with your hands.
5. The battery contains corrosive chemicals and flammable materials that may explode. Do not expose to heat sources like open flames or sparks. Do not transport batteries with flammable, explosive, or combustible materials. Keep tools and metal objects away from battery terminals to prevent short circuits and electric shock.
6. Do not use adapters not supplied with the product or that do not meet GB9706 and 1-2007 safety standards.
7. Do not use lithium batteries not supplied with the product.
8. Users are not permitted to disassemble the product without authorization.

Use of oxygen concentrator

1. Charging of external battery: Connect one end of the AC adapter to AC100~240V AC and the other end to the battery pack's input. A red light indicates charging; green indicates fully charged.
2. Connect external battery to use: Connect the battery pack's output port to the oxygen concentrator's power socket. A beep confirms the connection.
3. Connect AC adaptor to use: Plug the AC adapter's output port into the oxygen concentrator's power socket and connect the other end to 100~240VAC. A beep confirms the connection.
4. Connect the car power cord to the car to use: Connect the car power cord's input end to the car's cigarette lighter and the output end to the oxygen enricher's power socket. The red light on the cord and a single beep from the device indicate a successful connection.
5. Connect the disposable inhaler: Firmly attach the flared end of the disposable nasal cannula to the device's oxygen outlet. Wear the inhaler, adjust the outlet, and secure the fixing ring. Ensure the tube is not kinked or blocked to prevent alarms and ensure normal use.
6. Start the oxygen concentrator: Press the "power key". A "beep" indicates the device has started, defaulting to a 20-minute timer.
7. There are four time settings (20, 40, 60, 120 minutes). Press the "setting button" to select. Multiple indicators show the total time.
8. To stop during use, press the "power switch key", or it will stop automatically when the timer expires.
9. After stopping, the device enters standby mode after five minutes. To restart, press the "power switch" once to activate (a beep will sound), then press it again to enter the working state.

Precautions in use

1. Store and place battery packs correctly to prevent accidents and prolong product life.
2. Do not smoke or use near open flames while using the product.
3. Do not let children use it as a toy; keep it out of their reach to prevent accidents.
4. Keep the equipment at least 10CM away from objects or walls to ensure unobstructed air inlet and outlet.
5. Due to transport regulations, external batteries may ship with only test power or no power. Fully charge the battery before first use.
6. When the external battery's input port (charging port) is not in use, fasten the rubber cap to prevent short circuits or accidents.

Cleaning and maintenance

1. Before cleaning, unplug all external devices (AC adapter, external battery, oxygen inhaler) and ensure the equipment is turned off.
2. Do not get the equipment wet or allow water to enter. If water enters accidentally, stop use immediately and contact your dealer.
3. If the equipment is not used for a long time, seal the main unit in a plastic bag to prevent performance degradation due to humidity.
4. Disconnect power and battery after each use.
