• NOTE)
If the outdoor temperature during cooling operation is expected to be –5 °C
or less, do not install the outdoor unit lower than the indoor unit
.

ing the amount of refrigerant charge to be added” for the total amount of
refrigerant.
Pipe selection4. 2.
CAUTION
This unit is designed specifi 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)

Use a standard separation tube for pipe branching. Do not use a T tube as it does not
separate the refrigerant evenly.
