1. For hanging from the ceiling [Fig. 2.2.1] (P.2)
•
Provide an inspection hole 450 mm square in the ceiling surface as shown in
[Fig. 2.3.1] (P.2).
•
Install the unit in a suitable location (such as in the ceiling of a corridor or in the
bathroom etc) away from places regularly occupied. Avoid installing in the center
of a room.
•
Ensure a pull out strength of at least 60 kg per bolt for hanging bolts.
•
Be sure to install the BC controller horizontally.
Warning:
Be sure to install the unit in a place that can sustain the entire weight.
If there is a lack of strength, it may cause the unit to fall down, resulting in an
injury.
Caution:
Be sure to install the unit horizontally.
2.3. Securing installation and service space

*1 Dimensions with which pipe connection can be handled at site
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 simul-
taneously operated in different operation modes.

2.4. Checking the installation site
Check that the difference of elevation between indoor and outdoor units and the
length of refrigerant piping are within the following limitations.
