2. After the compressor speed stabilizes at 3000 rmp for about 10 minutes,
choose Run > Device Run State to view the Suction Pressure, Discharge
Pressure, and EEV Suct Superheat, and Supercool. Check whether the
suction pressure, discharge pressure, EEV suction superheat degree, and
supercool degree is within the reasonable range.

3. On the diagnostic mode screen, change the compressor input to 0 rpm.
Step 7 Commission the humidifier.
1. Confirm that the upstream inlet valve of the wet film humidifier is open.
2. In diagnostic mode, start the wet film humidifier.
3. Check that the water inlet pipe does not leak during the process.
4. In diagnostic mode, close the wet film humidifier.
Step 8 After the commissioning is complete, remove the device used for charging the
refrigerant, and install the valve bonnet.
