CAUTION
This unit is designed speci
fi
cally for use with the R410A refrigerant. Pipes for
R407C or R22 may not be used with this unit. Do not use existing pipes. Improper
pipe selection will degrade performance.

* If the selected pipe diameter between separation tubes (based on table "C") becomes
larger than the pipe diameter between outdoor unit branch kit and the
fi
rst separation
tube (based on table "B"), please select the pipe whose diameter is equal to the one
between outdoor unit branch kit and the
fi
rst separation tube.
(If pipe diameter C > B, select pipe size from table B)
* Total cooling capacity of indoor unit" is the total value for the cooling capacity of indoor
unit connected downstream.
* Discharge gas pipe size selection : When indoor unit of cooling only type is connected,
it calculates with the value except capacity of cooling only type.
