1. The wetting bottle should use bottled pure water or distilled water purchased from the supermarket (very important!) The bottle should not use tap water or mineral water. The amount of water to half of the wetting bottle is appropriate, otherwise the water in the bottle is easy to escape or enter the oxygen intake tube, the water in the bottle about three days to replace.
2. According to the manual requirements on a regular basis (about 100 hours of operation) to clean and replace the inner and outer sets of filter cotton, filter cotton must be thoroughly dried before it can be replaced into the machine.
3. After the machine is turned on, it should be placed on the ventilated ground and kept at least 30 cm away from the surrounding obstructions.
4. When the oxygen machine is turned on, do not make the float of the flow meter at zero (at least keep it above 1L, usually use it for 2L-3.5L).
5. In the process of transportation and storage should be kept upright, horizontal, inverted, wet is strictly prohibited.
6. Daily use should pay attention to the oxygen machine's unique "oxygen and nitrogen separation sound" to determine whether the machine is running normally: that is, there will be a continuous "bang ~ bang ~" two sounds every 7-12 seconds or so in the process of turning on the machine.
7. When you need to fill the oxygen bag, please note that after the oxygen bag is full, please follow the order of removing the oxygen bag first and then turn off the oxygen machine.
8. Long-term idle use of the oxygen concentrator will affect the molecular sieve activity (especially in humid conditions), it should be turned on for several hours a month to dry itself, or wrapped in plastic bags and kept in the original box.
