The Yuwell YU100 is a household health oxygen generator, also known as a homecare oxygen concentrator, designed for oxygen supplementation. It is suitable for families and individuals for health care and beauty care, but is contraindicated for patients with oxygen poisoning and oxygen allergy. The device is not intended for life support or life extension.

Function Description:

The oxygen generator operates by taking air as raw material and using a high-quality molecular sieve through the pressure swing adsorption (PSA) method at room temperature to produce high-purity oxygen. It is primarily composed of a compressor, adsorption tower, pressure regulating valve, reversing valve, circuit board, shell, and filter. The device features a full plastic shell for safety and reliability. It includes a remote control function, allowing for remote operation, and a "tired" function that displays the total working time on the screen. A thermal protector is integrated with the compressor to enhance the safety of both the compressor and the entire machine.

Important Technical Specifications:

Noise Level: Front 43 dB (A) (average); whole machine 50 dB (A)
Net Weight: 5.5 kg
Dimensions: 22 × 18 × 29 cm
Altitude: No reduction in oxygen concentration from sea level to 1828 m; less than 90% efficiency at 4000 m.
Security Systems: Current overload or loose connection shutdown, compressor high-temperature shutdown.
Electrical Classification: II equipment.
Work System: Continuous operation.
Normal Working Environment:
- Temperature range: 10°C to 40°C
- Relative humidity range: 30% to 75%
- Atmospheric pressure range: 860 hPa to 1060 hPa
Storage and Transport Environment:
- Temperature range: -10°C to +55°C
- Relative humidity: Not exceeding 93%
Fuse Tube Type: T1.6AL250V, Φ5×20

Usage Features:

Before installation and operation, users should check the product's appearance and ensure all accessories match the packing list. Any defects should be reported to the supplier or manufacturer.

Placement:

The oxygen machine must be kept away from flammable and explosive environments.
It should be placed in a well-ventilated indoor area, avoiding direct sunlight.
Maintain a distance of at least 10 cm from walls, furniture, and other objects.
Avoid placing the oxygen generator near heat sources, light and dark sources, wet and unguarded areas, smoke, pollution, or environments with excessively high or low temperatures.
No sundries or containers with water or oil should be placed on top of the oxygen generator.
It is forbidden to place any sundries at the bottom of the oxygen generator to prevent clogging of the inlet and outlet, which could lead to overheating, shutdown, or decreased oxygen concentration.

Preparation:

The oxygen machine must not be placed upside down.
If the power supply voltage is unstable (outside the ~220 V ± 22 V range), a voltage regulator should be installed.
Use a safe and qualified socket and wiring board certified by a safety electrician. Non-professional personnel should not open the chassis.
Plug in the power cord, ensuring the power switch is off before connecting to a safe grounding socket. Avoid using extended power cords.
Turn on the power switch to " | ". The machine's front panel will light up, displaying "tired," oxygen concentration, and flow gear, indicating normal operation. After a few seconds, the "tired" indicator lights out. A "chuckle-" sound every few seconds during operation is normal, indicating air exchange.

Oxygen Inhalation Operations:

Press "or" on the front of the machine to adjust the desired flow rate. The machine's front panel will display the corresponding oxygen concentration.
Connect one end of the oxygen tube to the outlet and the other end (oxygen head or suction head) to the user to begin oxygen inhalation.

Shutdown:

To temporarily stop oxygen inhalation during use, press the "key" on the front of the machine.
After use, unplug the oxygen pipe, turn off the power switch, and then unplug the power plug to cut off the power supply.

Remote Control Operations:

The remote control can operate the machine remotely, with functions consistent with the buttons on the oxygen generator.
For remote control operation, aim the remote control transmitting window towards the machine's remote control receiving window. The remote control code is 10011421.
The remote control is equipped with a CR2025 battery. If the remote control will not be used for a long time, remove the battery.

Electromagnetic Environmental Guidance:

Maintain at least 30 cm between the machine and other household appliances to avoid interference from strong electromagnetic environments.
Non-professional personnel should not disassemble the oxygen machine case. For product electrical schematics or professional maintenance, contact the manufacturer or after-sales service point.

Maintenance Features:

Before any maintenance, always cut off the power supply to avoid electric shock and do not disassemble the housing.

Cleaning the Enclosure:

Clean the outside of the housing at least once a month. Cut off the power supply, wipe with a clean, soft, wet cotton cloth or sponge, and ensure no liquid infiltrates the chassis slots.

Cleaning or Replacement of Filter Felt and Filter Cotton:

This is crucial for protecting the compressor and molecular sieve, and for prolonging the life of the oxygen generator. Clean and replace them in time.
WARNING: Do not operate the oxygen generator if the filter felt or filter cotton is not installed or is wet, as this can damage the machine.
Filter felt and filter cotton should typically be cleaned or replaced every 100 hours of operation.
Removal: The filter is located at the bottom of the machine. Pull out the filter cover to directly remove the filter felt and filter cotton.
The actual cleaning time for filter felt and filter cotton should be determined by usage time and environmental impact.
If there is visible ash on the felt or cotton, clean or replace immediately, regardless of service length.
Cleaning: Clean with a light detergent, rinse with clean water, and ensure they are completely dry before reinstallation.

Cleaning of Nasal Oxygen Tubes:

The nasal oxygen tube should be cleaned every three days.
The nasal suction head should be cleaned after each use, soaked in vinegar for about 5 minutes, then rinsed with clean water, or wiped with medical alcohol.
It is recommended to replace the oxygen tube every 2 months. Ensure the tube is kept dry.

Replacement of Fuse Tubes:

First, cut off the power supply.
Locate the fuse seat in the machine. Use a flat-head screwdriver to pry open the top cover, then unscrew the upper and lower covers of the fuse seat to remove and replace the fuse.

Troubleshooting Guidelines:

Oxygen generator has power but machine does not work, display screen does not show indicator:
- Possible Cause 1: Fuse of power supply. Exclusion Method: Replace fuse tube.
- Possible Cause 2: Insufficient power outlet. Exclusion Method: Do not use extension lines; move the oxygen generator to another power outlet or circuit.
- Possible Cause 3: If still not working, contact equipment supplier or manufacturer.
Oxygen generator has power, but oxygen supply air volume is very high, less, or none:
- Possible Cause 1: Oxygen pipeline kink or blockage. Exclusion Method: Straighten piping.
- Possible Cause 2: Filter felt. Exclusion Method: Clean or replace filter felt.
- Possible Cause 3: If phenomenon persists, contact suppliers or manufacturers.
Oxygen generator has power supply, but machine does not work and display screen shows "E1":
- Possible Cause 1: Compressor overheating protection, shutdown. Exclusion Method: Shut down, wait for the whole machine to cool before turning on.
- Possible Cause 2: If still not working, contact equipment supplier or manufacturer.
Note: If the failure cannot be eliminated, contact the supplier or manufacturer.

After-sales Service:
