Notes (1) When connecting the indoor unit type FDK, FDFL, FDFU or FDFW Series, limit the connectable capacity not higher than 130%.
(2) When the pipe extension length exceeds 510m, additional refrigerant oil must be charged (1,000 cc).
(3) It must be less than 30m when conducting the cooling operation with the outdoor air temperature lower than 10

C.
(4) If Superlink I (previous Superlink) is selected, all the range of usage and limitations, not only the limitations of connectable indoor capacity
and connectable number of indoor unit but also of the piping length, operating temperature range and etc., become same as those of KX4 (See
technical manual ’07·KX·KXR-T-114.). In addition to above limitations, all of new functions for KX6 and KXZ such as automatic address
setting function for multiple refrigerant systems and etc. will be cancelled.
(5) When it is required to install in a range of 50 to 90m, the limitation of use, etc. are different from those described here. For details, refer to
page 24.
(6) When it is required to install in the difference between the longest and shortest piping more than 40m, refer to page 23.
(7) It must be 40m or less, when it is required to use at the outdoor air temperature higher than 43°C.
(8) If the difference in the elevation is 18 to 30m, the limitation of use, etc are different from those described here. For details, refer to page 26.
