4. Refrigerant amount
Before shipment, this air conditioner is filled with
the rated amount of refrigerant including additional
amount required for air-purging, subject to 5m pip-
ing length. (The rated amount of refrigerant is indi-
cated on the name plate.) But when the piping
length exceeds 5 meters, additional charge is
required according to the following table.
