ADDITIONAL CHARGE OF REFRIGERANT
Refrigerant suitable for a piping length of 7.5m is charged in the outdoor
unit at the factory.
When the piping is longer than 7.5m, additional charging is necessary.
For the additional amount, see the table below.

Between 7.5m and 10m, when using a connection pipe other than that in
the table, charge additional refrigerant with 16g/1m as the criteria.
(The maximum length of the piping is 10m. If the units
are further apart than this, correct operation can not
be guaranteed.)
