Notes:
1. Hardnessinppmisequivalenttohardnessinmg/l.
2. Grains/gallon=ppmdividedby17.1.
3. Unitinternalheatexchangersarenotrecommendedforpoolapplicationsorwateroutsidetherangeof
thetable.Secondaryheatexchangersarerequiredforpoolorotherapplicationsnotmeetingthe
requirementsshownabove.
4. Saltwaterapplications(approx.25,000ppm)requiresecondaryheatexchangersduetocopperpiping
betweentheheatexchanger.
5. Filterformaximumof600micronsize.

1. Hardness in ppm is equivalent to hardness in mg/l.
2. Grains/ gallon = ppm divided by 17.1.
3. Unit internal heat exchangers are not recommended for pool applicaons or water outside the range of the table. Secondary
heat exchangers are required for pool or other applicaons not meeng the requirements shown above.
4. Saltwater applicaons (approx. 25,000 ppm) require secondary heat exchangers due to copper piping between the heat
exchanger.
5. Filter for maximum of 600 micron size.
