Total Dissolved Solids; Summary Of Water Chemistry Advice Affecting Warranty - Rheem Stellar Owner's Manual And Installation Instructions

TOTAL DISSOLVED SOLIDS

The stainless steel cylinder of the water heater is only covered by the Rheem
warranty when the total dissolved solids (TDS) content in the water is less than
600 mg / L.
Note: Some water analysis reports may state the conductivity of the water
rather than the level of total dissolved solids. Conductivity, measured in
microsiemens per centimetre (µS / cm), is directly proportional to the TDS
content of the water. TDS, in mg / L, is approximately 70% of the conductivity in
µS / cm.

SUMMARY OF WATER CHEMISTRY ADVICE AFFECTING WARRANTY

The water heater and its components are not suitable for certain water
chemistries. Those chemistries are listed below. If the water heater is
connected at any time to a water supply with the following water chemistry, the
Rheem warranty will not cover any resultant faults on the components listed
below:
Water Chemistry
Chloride > 250 mg / L
pH < 6.0 or > 9.5
Total Dissolved Solids (TDS) > 600 mg / L
Saturation Index (SI) < -1.0
Saturation Index (SI) > +0.4
(if expansion control valve is not fitted)
Saturation Index (SI) > +0.8
Magnesium > 10 mg / L
Iron > 1 mg / L
Sodium > 150 mg / L
