3.2.1 (Optional) Refrigerant R410A

Do not use inferior refrigerant. Otherwise, Huawei has no responsibility for the damage
caused by the inferior refrigerant.
The following methods are recommended to identify the refrigerant.

You are suggested to use R410A from the brand of Dupont, Daikin, Honeywell, or the
same quality refrigerant.
Dial the hotline of the refrigerant producer to confirm its reliability.
As shown in Figure 3-24, put the refrigerant indoor for 24 hours. Then use a
thermometer to measure the external surface temperature of the refrigerant cylinder, and
connect a pressure gauge to the cylinder to measure its internal pressure. As shown in
Table 3-2, the saturation pressure that corresponds to the external surface temperature,
and calculate the deviation from the internal pressure. If the deviation is more than 0.2
MPa, the refrigerant is not in good condition. Replace it.
