How to Select “EarthWise”

OD Parameter Setting:

Set leaving water temp to 5°C

via central controller

  • In-Door Unit Selection:

  • Concealed unit: select “Earthwise” application

  • High wall & Cassette: Not available

  • Digit 17: Application

  • N = Normal application

  • E = Earthwise

Choose “Earthwise” option in TDS tools to run product configuration report

PVC Pipe Installation Benefits

  • PVC pipe and fitting price is 4 times cheaper than steel pipe’s.

  • PVC Pipe weight is 6 times less than steel pipe’s.

  • Use smaller pipe size because friction loss of PVC pipe is much less than steel pipe’s.

  • Easy transportation, Easier and quicker installation, longevity
