How to increase oxygen flow on DEDAKJ DE-2AW?
If the machine runs normally but the oxygen flow is small, try these steps: 1. Increase the flow by turning up the flow gear. 2. Check the oxygen inhalation tube for kinks or blockages and straighten it out. 3. If the issue persists, there may be a problem with the connecting pipe inside the machine. Disconnect the power cord and contact professionals for repair.
Why does my DEDAKJ DE-2AW Medical Equipment smell?
An odor from your DEDAKJ Medical Equipment can be normal, especially when the machine is new. The connecting pipe and plastic parts may emit an odor that is non-toxic and harmless, which should disappear with use. Alternatively, the odor could be due to a dirty humidification water tank that has not been cleaned or replaced recently. In this case, clean the oxygen inhalation tube and humidification water tank.
What to do if water flows out of the oxygen outlet of DEDAKJ Medical Equipment?
If water flows out of the oxygen outlet, it could be due to two reasons. First, the water level in the humidification water tank may be exceeding the maximum level, causing air flow to press bubbles into the suction pipe. Reduce the water in the humidification tank to be below the max level. Second, water vapor may have converged on the pipe wall during long-term use. Pour out the water in the water tank, and then add water to the water tank after no water flows out from the oxygen outlet.
Why DEDAKJ DE-2AW is not working normally after start-up?
If the indicator light is normal, but the machine isn't working correctly and makes an abnormal sound, there could be a few reasons. It might be a compressor fault, in which case you should cut off the power supply and ask professional maintenance personnel to repair it. Alternatively, the ambient temperature might be too high, triggering the self-protection program of the oil-free compressor. This is normal, and the machine will restart automatically once the temperature drops. Finally, the connecting pipe inside the machine might have fallen off or broken. In this case, cut off the power supply and ask professional maintenance personnel to repair it.
What to do if there are bubbles in the water tank but no oxygen from DEDAKJ DE-2AW?
If you see bubbles in the water tank after starting up, but no oxygen is coming out of the oxygen outlet, the rubber plug of the humidification water tank may not be properly inserted. Remove the humidification water tank and re-insert it correctly.
