Troubleshooting
Cleaning water tank
To keep the water tank clean, the water used should be pure water,
distilled water or cold boiled water. we suggest to change water every day.
The water tank should be cleaned every week. First use mild detergent
and shake the tank to wash. Then use clean water to rinse it,
After cleaned the water tank, please remember to put water tank plastic
plug back to avoid leakage of oxygen from the water inlet, caused no
oxygen output from oxygen outlet mouth when the machine is in normal
working.
Air filter cleaning and replacement
The white air filter at the back of the machine can reduce noise, isolate
dust and purify the air. It should be cleaned around every ten days. First
use mild detergent to wash, and then rinse it with clean water. Pay special
attention that it must be dry to be positioned back, or the function of the
molecular sieve could be damaged, which will lead to decreased oxygen
concentration.
Cleaning oxygen Inhaler and atomizing components
Oxygen inhaler should be cleaned after use, and the nasal suction head
on the nasal inhaler should be cleaned and disinfected after use.
Soaking the inhaler in the solution of 5% potassium ferric acid for 5
minutes, cleaning with water, or wiped with alcohol. Oxygen tube as
consumable should be replaced regularly.

In the initial stage of using,
there is smell for the
