*1: If future extension is planned, select the tubing diameter based on the total horsepower after extension.
However extension is not possible if the resulting tubing size is two ranks higher.
*2: The balance tube (outdoor unit tube) diameter is ø3/8" (ø9.52).
*3: Type 1 tubing should be used for the refrigerant tubes.
*4: If the length of the longest tube (L1) exceeds 295 ft. (equivalent length), increase the main tube (LM) size by 1 rank for the
suction, discharge, and liquid tubes. (Use field-supply reducers.) (Select from Table 1-10 and Table 1-15.)
*5: If the longest main tube length (LM) exceeds 164 ft., increase the main tube size at the portion before 164 ft. by 1 rank for
the suction tubes and discharge tubes.
(For the portion that exceeds 164 ft., set based on the main tube sizes (LA) listed in the table above.)

*1: If the total capacity of the indoor units con-
nected to the tube ends is different from the
total capacity of the outdoor units, then the
main tube size is selected based on the total
capacity of the outdoor units.
