1-5. Tubing Size

(A) Single type
● Refrigerant tubing between the indoor and outdoor units
should be kept as short as possible.
● The lengths of the refrigerant tubes between the indoor and
outdoor units are limited by the elevation difference between
the 2 units. During tubing work, try to make both the tubing
length (L) and the difference in elevation (H1) as short as
possible. Refer to Table 1-7.
Single
(B) Simultaneous operation multi (Twin, Triple, Double-Twin)
N OT E
Because the indoor units run simultaneously, install them within the same room.
