•
Hardness less than 7 grains (120 mg/L) (Commercial Use -
water temperatures of 140
• 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 affect.
