NOTICE
The maximum length of the connection pipe is listed in the table below. Do not place the units
such that the distance between them exceeds the maximum length of the connection pipe.
NOTES:
1. The connection pipe should be insulated with proper water-proof insulating material
2. Wall thickness of pipe 0.5-1.0 mm (0.02-0.04 in): bearing pressure 435 PSI (3.0 MPa)
3. Shorter connecting pipe lengths result in greater thermal efficiency, so it is preferable to reduce
connecting pipe lengths where possible.
4. See the oil trap instructions on page 21 for specific requirements when there is height
difference between the indoor and outdoor unit greater than 20 feet.
