Common problems and troubleshooting of Yuyue oxygen concentrator

Fault phenomenon 1: Power outage alarm

Press the power switch, the oxygen concentrator will continuously beep, the red alarm light will turn on, the display screen will not show, and the machine will not operate.

Root cause analysis

1. The power cord plug is not securely plugged in
2. The socket has no power output
3. The reset switch is blown and lifted
4. After simple processing, it still doesn't work. Contact the repair center for troubleshooting methods
5. Re plug the power cord plug
6. Replace the power socket with electricity
7. Press the reset switch to reset
8. The fault still requires direct appointment for after-sales maintenance

Fault phenomenon 2: The machine is running normally, but there is little or no oxygen output

The startup sound and flow meter adjustment are normal, but the oxygen output is extremely low or completely absent.

Root cause analysis

1. Moisturizing bottle and bottle cap seal leak air
2. The safety valve of the humidification bottle is in the open state
3. Methods for eliminating defects such as broken or blocked nasal oxygen tubes
4. Re tighten the humidification bottle and bottle cap
5. Reset and close the safety valve
6. Replace with a brand new nasal cannula
7. Contact professional maintenance for ongoing issues

Fault phenomenon three: The machine is working and both green and yellow lights are on

Root cause analysis

1. Oxygen concentration between 50% and 82%
2. Exclusion method for oxygen flow exceeding the standard range of 3L/min
3. Clean or replace the filter screen
4. Adjust the oxygen flow rate to the standard gear according to the doctor's advice

Fault phenomenon four: red light on, alarm display E1

Reason: Abnormal system circulation pressure, minor malfunction can be continued for a short period of time

Exclusion: Cleaning or replacing the filter screen can alleviate the problem

Fault phenomenon five: Red light on, alarm display E2

Reason: Compressor circuit overcurrent

Exclusion: Immediately stop the machine and stop using it, contact after-sales for on-site repair

Fault phenomenon six: Red light on, alarm display E3

Reason: Compressor circuit overcurrent

Exclusion: Stop using immediately, do not disassemble the machine by yourself, make an appointment for professional maintenance

Fault phenomenon seven: Red light on, alarm display E4

reason

1. Oxygen concentration below 50%
2. Oxygen flow rate exceeds 3L/min
3. Troubleshooting methods for display board circuit faults
4. Clean and replace the filter screen
5. Check and replace internal connecting wires

Fault phenomenon 8: Red light on, alarm display E6

Reason: Communication failure on the device motherboard

Exclusion: Immediately shut down the machine and cut off the power, contact the maintenance center for professional handling

Symptom 9: Excessive fog and water accumulation in the oxygen supply pipeline

Drainage tip: Connect the pipeline after turning on the machine, and repeatedly open and close the pipeline port with your fingers to drain the internal water droplets.

Root cause analysis

1. The machine is not ventilated and the working temperature is too high
2. The temperature of adding water to the humidification bottle is too high
3. Adding water to the humidification bottle exceeds the maximum water level line
4. Sudden shutdown during oxygen inhalation
5. Sudden shutdown after nasal cannula bending and pressure build-up
6. Troubleshooting method for heat dissipation difference caused by internal fan not turning or low speed
7. Reserve a ventilation space of at least 10cm around the machine, away from obstructions and heating equipment
8. Moisturizing bottles should only be filled with lukewarm water, and heating water is prohibited
9. Add water and control it between the high and low water level marks
10. Stop the machine first if there is water accumulation, restart and drain the water vapor before use
11. Straighten out the nasal oxygen pipeline to avoid bending and squeezing
12. Clean up foreign objects on the fan, replace the damaged fan in a timely manner

Fault phenomenon ten: Small atomization amount, unable to atomize (ZH-I-3LW type specific)

Root cause analysis

1. Improper installation and incorrect connection of atomization accessories
2. Deformation of atomization components after cleaning and disinfection
3. Atomization nozzle blockage
4. Methods for eliminating excessive medication injection
5. Clean or replace the primary filter screen
6. Clean and replace the secondary filter felt
7. Do not use plug and drop cables, replace with a stable independent socket
8. Straighten out the intake pipeline to ensure smooth intake
9. Stop immediately if the fault persists, contact the oxygen generator for maintenance
