System piping length (Charging with refrigerant)

At the time of shipment from the factory, the outdoor unit is charged with enough refrigerant for an equivalent

pipe length of 30m.

If the equivalent piping length used is 30m or less, no additional charge will be necessary.

If the equivalent piping length is between 30 and 70m, charge with additional refrigerant according to the

equivalent length given in the following table.
