Huawei NetCol8000-A Series Quick Manual page 19

If the R410A refrigerant is provided by Huawei, put the refrigerant steel vessel upside down when
charging in the refrigerant. If the refrigerant is not provided by Huawei, check with the refrigerant
provider whether the steel vessel has a siphon. If the vessel has a siphon, put it upside up when
charging in refrigerant. If the vessel has no siphon, put it upside down when charging in refrigerant.
These measures ensure that the refrigerant is charged in the liquid form.

NOTE
If one NetCol8000-A090D is used with two NetCol500-A060s (or one NetCol500-A120) and the L
is 80 m, the 9.4 + (80-10) ×0.28=29 kg needs to be filled in each compressor system. In total, the
NetCol8000-A090D needs to charge 58 kg R410A.
