Failure of electric elements due to lime scale build-up on the
heating surface, low pH, or other imbalance IS NOT covered by
the warranty.
• 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 ll 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 ll 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 aect.
*NOTE: To promote appliance service life, it is strongly
recommended to follow the maintenance procedures in this
manual.
