1-12. Installation Instructions

Tubing Length

(A) Single type
Keep refrigerant tubing between the indoor and outdoor
units as short as possible.
The length 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.

(B) Simultaneous operation multi (Twin, Triple, Double-Twin)
NOTE
Because the indoor units run simultaneously, install them within the same room.
