1. Safety Use Specifications
Oxygen is combustible. When using an oxygen generator, it must be kept at least 10 meters away from open flames and heat sources (such as gas stoves and electric heaters). Smoking or approaching flammable items containing alcohol is prohibited. The oxygen generator should be placed in a well-ventilated location to avoid curtains and furniture blocking the heat dissipation port. The body should be placed horizontally and kept 15-30cm away from the wall. The oxygen generator should use an independent power socket to avoid voltage instability affecting the operation of the compressor. Ensure that your hands are dry when plugging and unplugging the power supply.

2. Product Parameter Adjustment
Flow Selection: 1-2L/min is recommended for health care populations, and COPD patients need to adjust according to doctor's advice (usually more than 5L/min).
Concentration Control: The oxygen concentration of medical-grade oxygen generators must be ≥90%, and it should be calibrated regularly with an oxygen concentration detector to avoid the performance of the molecular sieve from deteriorating after long-term use.
Humidifier bottle management: Use pure water or distilled water, change the water daily and disinfect the humidifier bottle weekly.

3. Daily maintenance and care
First-level filter cotton: Clean once a week, dry and reinstall to avoid dust clogging and affecting the air intake efficiency.
Secondary filter: Replace every 900 hours or when it turns black to prevent oxygen pollution.
Body maintenance: Wipe the body with a dry cloth every week to prevent liquid from penetrating into the circuit. When not in use for a long time, turn on the machine for 1 hour every month to prevent the molecular sieve from getting wet.
