Do not use refrigerant of poor quality. Huawei will not be liable for any device
damage caused by using refrigerant of poor quality.
Verify that the refrigerant is authentic in the following ways:

Dial the refrigerant vendor's hotline to confirm the refrigerant authenticity.
As shown in Figure 8-22, place the refrigerant in an indoor place with
constant temperature and humidity for 24 hours. Then, use a thermometer to
measure the temperature of the refrigerant tank outer surface and connect a
pressure gauge to the pressure tank to measure the internal pressure. Find the
saturation pressure corresponding to the measured outer surface temperature
from Table 8-6. If the deviation between the saturation pressure and the
measured internal pressure is greater than 0.2 MPa, the refrigerant does not
meet the requirements and needs to be replaced.
