The piping length exceeds 30 metres.
APPLICABLE FOR ALL MODELS
Before shipment, this air conditioner is filled with the rated
amount of refrigerant subject to 30m piping length. (The
rated amount of refrigerant is indicated on the name plate.)
But when the piping length exceeds 30m, additional charge
is required according to the following table.

For other pipe length of other installation multiply
by the following correction factor to determine the
