Notes:
*1 Refer to "Restrictions on piping length" on P. 4.
*2 Please refer to the figure "Distance between BC controller and farthest
Indoor unit" when the distance between BC controller and farthest in-
door unit exceeds 40 m. (Not applicable to the P250 model indoor unit)
*3 The values in the parentheses show the maximum piping length to be
followed when the connection capacity of the indoor unit is 200 or more.
*4 In the system to which indoor units of the P200 model or above are con-
nected, neither a branch joint nor a branch header may be used.
*5 Do not connect the P200 or P250 models of indoor units and other mod-
els of indoor units at the same port.
*6 In the system to which indoor units of the P100 through P140 models are
connected, merge the two ports before connecting them. (Set DIP SW4-6
on the BC controller to ON.)
*7 It is possible to connect the P100 through P140 models of indoor units to
a single port. (Set DIP SW4-6 to OFF.) Note that the cooling capacity will
somewhat decrease. (The factory setting for DIP SW4-6 is OFF.)
*8 Indoor units that are connected to the same branch joint cannot be si-
multaneously operated in different operation modes.
