Tubing Size
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.
