Connection piping requirements
9
Wall Unit
NOTICE
Maximum length of connecting piping is shown in the following table. While placing the units confirm that
the distance in between them exceeds the maximum length of connection piping.
NOTES:
1. Connecting piping must be covered with waterproof insulating material.
2. Tubing thickness 0.5-1.0 mm (0.02-0.04 in): bearing pressure 3.0 MPa
3. Shorter lengths of connecting tubing produce higher thermal efficiency and therefore it is preferable to reduce connection tubing
lengths whenever possible.
4. See oil trap instructions on page 21 for specific requirements when there exists a height difference superior to 20 feet between
the indoor unit and the outdoor unit.
