Connection Pipe Requirements
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 specications.
NOTES:
1. The connection pipes should be insulated with proper water-proof insulating material
2. Wall thickness of pipe 0.02-0.04 in (0.5-1.0 mm): bearing pressure 435 PSI (3.0 MPa).
3. Shorter connecting pipe lengths result in greater thermal eciency, so it is preferable to reduce
connecting pipe lengths where possible.
4. Refer to the oil trap instructions for specic requirements when there is height dierence
between the indoor and outdoor unit greater than 20 feet (6m).
