(Optional) Refrigerant R410A
CA UTION
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.
1. You are suggested to use R410A from the brand of Dupont, Daikin,
Honeywell, or the same quality refrigerant.
2. Dial the hotline of the refrigerant producer to confirm its reliability.
3. As shown in
, 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
, 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.
