M : Medium
L+ : Low+
L: Low
L- : Low
UL : Ultra Low
SUL : Super Ultra Low
* The air volume broadly varies due
to position of the louver, etc.
The described value indicates one
under condition of inclining
downward blowing.
1) When setting the air volume to
M, M+, L, L-, or H on the remote
controller, the operation is
performed with the constant air
volume of the air volume level
shown in Fig. 1.
2) When setting the air volume to
AUTO on the remote controller,
rotation of the fan motor is
controlled to the air volume level
shown in Fig. 2 and Table 1
according to the setup tempera-
ture, room temperature, and heat
exchanger temperature.
