5) Additional Charge
The refrigerant is pre-charge 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 standard piping length then use the addi-
tional charge value as indicated in the table.

Example: FCRN24F & RN24C with 13m piping length, additional piping length is 5.5m. Thus,
Additional charge = 5.5[m] x 10[g/m]
=
55[g]
