The refrigerant is pre charged in the outdoor unit. If the piping length is less than 7.5m, then additional charge after vacuuming
is not necessary. If the piping length is more than 7.5m, then use the additional charge value as indicated in the table.
Additional refrigerant charge [g] per additional 1m length as tabulated
Indoor
Outdoor
Additional charge [g/m]
Example:
ATXB50CV1B & ARXB50CV1B with 12m piping length, additional piping length is 4.5m. Thus,
Additional charge = 4.5[m] x 20[g/m]
