NOTICE
The maximum distance of the connection piping in both height and total length is provided in the
table below. Do not install these units in locations that exceed these specifications.
NOTES:
1. The connection pipes should be insulated with proper water-proof insulating material
2. Use type ACR copper piping.
3. Shorter connecting pipe lengths result in greater thermal efficiency, so it is preferable to reduce
connecting pipe lengths where possible.
4. Refer to the oil trap instructions for specific requirements when there is height difference
between the indoor and outdoor unit greater than 20 ft. (6m).
