5. Measure from the indoor unit down the wall and over to the outdoor unit. Make sure you measure the
exact route you plan on running the line set from the indoor unit to the outdoor unit. If the length is
longer than 25 feet, you will need to purchase additional line set and communication cables.
6. Follow step one for each indoor unit and make sure you purchase the correct lengths needed to do
your job. Then go to steps on how to install the Mini-Split.
• Hang the indoor units
• Place the outdoor unit
• Run the line sets
• Etc.
NOTE:
You will also need to purchase new communication cables since the default length that comes
attached to the indoor unit from the factory is 25 ft. Refer to the chart below regarding max line set lengths for
each system. See page 9 for longer communication cable sku number.

NOTE:
Refrigerant pipe should be as short as possible with a 10 ft minimum.
NOTE:
Longer is better than shorter, you can always coil the additional line set.
• If the line set run is shorter than 25 ft., you can opt for a 15 ft. line set.
• If your line set will be longer than 25 ft., you will need to purchase additional lengths in 15-foot
increments.
Do not try to solder/braze 2 line sets together to make it longer.
This will void the warranty.
