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 7.5m then use the additional charge value as indicated in the table.

Example:
CK25E & SL25C with 13m piping length, additional piping length is 5.5m. Thus,
Additional charge = 5.5[m] x 38[g/m]
= 209[g]
IMPORTANT: * These values are for information only. They should be checked and selected to comply with local and/or
national codes and regulations. They are also subject to the type of installation and size of conductors.
