Do not use low-quality refrigerant. Huawei is not responsible for any damage caused by
low-quality refrigerant.
Follow these suggestions to choose high-quality refrigerant:
1. Use high-quality brands such as DuPont, Daikin, or Honeywell.
2. Contact the refrigerant producer to confirm the refrigerant authenticity.
3. Check the refrigerant by following the steps shown in Figure 3-1: Keep the refrigerant
indoors at a constant temperature and humidity for 24 hours. Use a thermometer to
measure the external surface temperature of the refrigerant container, and connect a
pressure gauge to the container to measure its internal pressure. Determine the saturation
pressure that corresponds to the measured external surface temperature according to
Table 3-7 and calculate the deviation from the measured internal pressure. If the
deviation is more than 0.2 MPa, the refrigerant is not qualified and should be replaced.
