	(ø9.52)	(ø12.70)	(ø15.88)	(ø19.05)

*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.)
