Steps of Use Oxygen Concentrator DE-1A/DE-1B（ddt-1a 1b）
① Drainage of water tank
Drain the water tank as shown in the Figure on the left.
② Water injection
Open the rubber plug on the top of the water tank and inject pure water (cold boiled water or distilled water) to below the highest water level, then install the rubber plug of water tank back to its original position (remember to install the rubber plug of water tank back to the original position, so as to avoid no oxygen output from the oxygen outlet during normal operation of the machine due to oxygen leakage from the water filling port). Then, align the humidification water tank with the outlet of the oxygen machine water tank, align it with the bottom clamping slot, and install the humidification water tank back to its original position.
※It should not be higher than the highest water level. Water injection is not necessary, and it is only for humidifying oxygen gas. You may not inject water if you don't think the oxygen is dry.
③ Check "air filter"
Open the air inlet cover and check whether the "air filter" is installed in place and clean.
④ Connect the power line
As shown in the Figure on the left, insert the output end of the power line into the power socket of the oxygen machine, and then insert the other end of the power line into the socket.
⑤ Connect the oxygen inhalation tube Insert the large-diameter end of the oxygen inhalation tube into the "oxygen outlet" of the host engine.
※ If there are too many water drops in the water collector during or after oxygen inhalation, please open the water collector and pour out water.
⑥Wear the oxygen inhaler
As shown in the Figure, when using the ear hook type oxygen inhaler, adjust the position of the oxygen outlet and align it with the nostrils; when using a snuffing oxygen inhaler, please align the two outlets with the nostrils and tighten the rubber ring.
⑦ Start the oxygen machine
Turn on the "power switch" and touch the "Start/Stop" key gently. Then, the machine will start to produce oxygen, and the user can inhale oxygen.
Please adjust the oxygen concentration to the corresponding gear according to the practical situation. Recommended oxygen concentration: 70%~90% for special people (please do not inhale high-concentration oxygen unless otherwise advised by the doctor) The oxygen concentra- tion of 50%~70% is suitable for the elderly and pregnant women, and 30%~50% is suitable for office workers and students, or please consult a physician.
