WATER QUALITY REQUIREMENTS
Incoming water in excess of 3.0 grains of hardness per gallon (GPG) (.75 grains of
hardness per liter) must be treated and softened before being supplied to booster
heater(s).Water containing over 3.0 GPG (.75 GPL) will decrease the efciency and
reduce the operating life of the unit.
Note: Product failure caused by liming or sediment buildup is not covered
under warranty.
