Precautions Warning: This is not a medical device and is not considered life-support or life-sustaining equipment. Warning signs on the product are designed to help users understand and use this product correctly to prevent damage and a property loss.The main warning signs and meanings are as follows: Prohibited action Required action Keep dry Caution (Warnings and dangers) Class II equipment This side up The machine shall be placed indoors. Keep the room well-ventilated and avoid direct sunlight. Keep the product more than 30 meters away from the walls and other objects. Do not place miscellaneous items and liquid containers on the machine case. It is prohibited to stack sundries at the ventilation hole on the back of the machine to prevent clogging of intake and exhaust, which may lead to excessive temperature and thus cause improper shutdown or a decrease in oxygen concentration. To avoid the machine being interfered by strong electromagnetic environment or interfering with other electrical appliances, please keep it at least 3 meters away from other household appliances when using. Do not place the machine upside down or laid it horizontally. If the voltage is unstable and exceeds the range of 220±15V, please connect the voltage regulator before use. Please use a safe and qualified socket and a terminal block with safety electrician certification. Oxygen is a combustion-supporting gas. Therefore, when using the machine,do not smoke and keep away from the fire source to avoid a fire hazard. Do not turn on and off the machine too often. Turn off the machine for 3-5 minutes before restarting to maintain the normal service life of the machine. No oil or greasy substance should be used in any part of the machine. Do not use the machine without an air filter. Do not bend the oxygen-inhalation tube when using the machine, otherwise, it will affect the normal output of oxygen. Unauthorized personnel should not disassemble the cover. Do not bend the oxygen-inhalation tube when using The machine otherwise it will affect the normal output of oxygen. Unauthorized personnel should not disassemble the cover. 2. Working Principle Air enters the compressor after being filtered through the inlet filter device, and is compressed into the molecular-sieve tower for oxygen-nitrogen separation. Oxygen passes through the molecular-sieve tower and enters the fine sieve tower, while nitrogen is adsorbed by the molecular sieve and discharged into the atmosphere through the separation valve. With the increase of oxygen concentration in the fine sieve tower, oxygen is finally delivered to the user through the oxygen delivery pipe under the control of the electronic flow control valve.

Product Description This product is applicable to AC 230V/50Hz(110V/60Hz) voltage. It is equipped with a pure copper oil-free compressor and a high-quality molecular sieve. It uses air as raw material to produce high-purity oxygen through a new Pressure Swing Adsorption method (PSA) at room temperature, which can be used for household supplementary oxygen absorption. The product is designed according to a standard higher than the standard for household appliances. It is fitted with a large clear LED display screen. With intelligent chips controlling the circuit, the machine has automatic fault alarm function, timing function and overheating circuit protection function. When the working temperature of the compressor is too high, it will automatically stop working to better protect the safety of the compressor and the whole machine. This product is easy to operate, lightweight and portable. It is not only suitable for home use, but also can be used in a car by using the automobile power supply.Suitable for household oxygen supplement. 4.

Maintenance and Repair Clean the shell The shell surface should be cleaned at least once a month. Cut off the power supply and wipe it with a clean, soft, slightly wet cloth soaked in disinfectant. Prevent the liquid from seeping into the interior of the machine. Clean or replace filter and filter pad The white air filter at the back of the machine can reduce noise, keep the dust out and purify air. Timely cleaning and replacement of the filter are of great importance to protect the compressor and molecular sieve and prolong the service life of the machine. So please clean or replace it in time. Do not operate the oxygen concentrator when the filter and filter pad are not installed or are wet, which could cause permanent damage to the machine. Generally, filters and filter pads shall be cleaned or replaced every 100 hours. Filter cotton Filter Air inlet cap Disassembly: Pull out the air inlet cover outward from the back of the machine to remove the filter. Whether to clean or replace the filter and filter cotton shall be determined according to the actual use conditions. If the filter is dirty or clogged, it should be cleaned or replaced immediately regardless of the using time. Note: Filters and filter pads are consumables and need to be replaced regularly. Cleaning: Clean with diluted detergent first and rinse with water. Install it on the machine after it is completely dry. Clean the oxygen inhaler and atomization components Cleaning should be done after each use. The nasal suction heads on the nasal cannula should be cleaned and disinfected after each use. Soak in 5% potassium permanganate solution for 5 minutes, and then clean it with clean water; or wipe it with alcohol. Fuse replacement Unplug the power, use a slot screwdriver to pry open the fuse cap (as shown in the diagram), remove the invalid glass fuse, and then install a new one. Put the fuse cover back in place and tighten it. Prize up the fuse cover with a small slotted screwdriver Remove the damaged fuse Install the fuse cover Spare part During use Install a valid fuse Long-term idle Make the following preparations if the machine shall be in long-term idle. 1. Cut off the power supply and put away the power cord. 2. Store the machine in a dry environment at room temperature. Do not bend the tube. 3. Avoid direct sunlight and pollution. 4. Place the machine out of reach of infants and children. Make the following preparations before using the machine which has been in long-term idle. 1. Check the power cord for normal use. 2. Clean the oxygen tube and inhaler to avoid clogging or bending. 12.
