Gree GMV6 DC Inverter VRF Units Service Manual
In step "13 Refrigerant charging running" is divided into trial running in manual charging cooling
mode or manual charging heating mode. The system automatically determines and enables indoor unit
cooling or forcibly enables indoor unit heating. When the system runs for 60 minutes without exception, it
determines that the refrigerant is normal, the unit is shut down, and the commissioning is completed.
Alternatively, after staying for 65 minutes in the process, the commissioning is exited and completed.
The interface after the commissioning is shown below. "Debugging completed" indicates that the
commissioning is completed, and the system enters normal standby status 5 seconds later. Step "13
Refrigerant charging running" is reserved.
