• Hardness less than 12 grains (200 mg/L) (Residential Use - water temperatures below 140
o
F)
• Hardness less than 7 grains (120 mg/L) (Commercial Use - water temperatures of 140
o
F and greater)
• Hardness levels above the required amounts can lead to lime scale build-up throughout the system. Water below 5 grains/gallon
(85 mg/L) may be over softened.
• Consult local water treatment companies for unusually hard water areas (above the required amounts) or for other treatment
solutions if water is being over softened (below 5 grains/gallon [85 mg/L]).
• Chloride concentration less than 100 ppm (mg/L)
• Do not fill appliance or operate with water containing chlorides in excess of 100 ppm (mg/L).
• Using chlorinated fresh water should be acceptable as levels are typically less than 5 ppm (mg/L).
• Do not connect the appliance to directly heat swimming pool or spa water.
• Total Dissolved Solids (TDS) less than 500 ppm (mg/L)
• Total dissolved solids are minerals, salts, metals, and charged particles that are dissolved in water.
• The greater the amounts of TDS present, the higher the corrosion potential due to increased conductivity in the water.
• If using softened water to fill the appliance, it is still possible to have high TDS. This water can be corrosive. Consult local water
treatment companies for other treatment solutions to reduce this effect.
*NOTE:
To promote appliance service life, it is strongly recommended to follow the maintenance procedures in this manual.
