tives, then this is your own responsibility. The warranty on the product delivered by

the chemical additives have not been approved by A.O. Smith.
- On installation and during additions or changes at a later stage, A.O. Smith recom-
mends to keep a record of the type of water used, its quality at the time, and if ap-
plicable, which additives and quantities were added.
