If the suction pressure, discharge pressure, and suction overheating degree is without
normal ranges, check and make sure that:
1. Charge refrigerant in an amount exactly as standard charge required.
2. The air inlet and outlet of outdoor unit are without block.
If the problem remains unresolved after troubleshooting, please contact Huawei
technical support.
Step 7 (Optional) Commission the
humidier.
1. On the home screen, Choose Maint > Diagnostic Mode > Enter and set
Humidier to 50%.
2. The water supply valve opens and water is charged into the humidier
cylinder automatically. After the water level reaches a threshold, the water
supply valve closes. You need to check that the water inlet pipe does not leak
during the process.
3. After 3 to 10 minutes, choose Running > Device Details >
Humidier and
check that the value of Current in cylinder is greater than 1.2 A and that no
alarm is generated, which means that the
humidier works properly.
4. On the home screen, Choose Maint > Diagnostic Mode > Enter, set
Humidier to 0%, and then click On after Water inlet solenoid valve. The
humidier cylinder starts to drain water. You need to check that the drainpipe
does not leak during the process.
Step 8 (Optional) Commission the water pump. Open the cover in front of the water pan
and lift the low liquid level detector. The pump starts working after 5 seconds.
Then release the liquid level detector and shut down the pump.
NO TE
It is normal if a pump alarm is generated during the pump operation when there is no
water in the pan. The pump generates this alarm for self-protection.
Step 9 After the commissioning is complete, remove the device used for charging the
refrigerant, and install the valve bonnet.
Step 10 On the Diagnostic Mode screen, tap Exit and then Yes to exit the diagnostic
mode.
Step 11 Go back to the startup screen, and tap Shutdown.
