- Should you wish to achieve the required water quality by using chemical addi
-
tives, then this is your own responsibility. The warranty on the product delivered by
A.O. Smith expires, if the water quality does not meet A.O. Smith's specifications or
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.
