Tubing Length
(A) Single type
z
Keep refrigerant tubing between the indoor and outdoor
units as short as possible.
z
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.
