Warranty

If within one year of the original installation date of a storage tank supplied by
A.O. Smith, following verification, and at the sole discretion of A.O. Smith, an
assembly or part (with exclusion of the tank) proves to be defective or fails to function
correctly due to manufacturing and/or material defects, then A.O. Smith shall repair
or replace this assembly or part.
If within 3 years of the original installation date of a storage tank supplied by
A.O. Smith, following verification, and at the sole discretion of A.O. Smith, the glass-
lined steel tank proves to be leaking due to rust or corrosion occurring on the water
side, then A.O. Smith shall offer to replace the defective storage tank with an entirely
new storage tank of equivalent size and quality. The warranty period given on the
replacement storage tank shall be equal to the remaining warranty period of the
original storage tank that was supplied. Notwithstanding that stated earlier in this
article, in the event that unfiltered or softened water is used, or allowed to stand in
the storage tank, the warranty shall be reduced to one year from the original
installation date.
The warranty set out in articles 1 and 2 will apply solely under the following
conditions:
a. The storage tank is installed under strict adherence to A.O. Smith installation
instructions for the specific model, and the relevant government and local
authority installation and building codes, rules and regulations in force at the time
of installation.
b. The storage tank remains installed at the original site of installation.
c. The storage tank is used exclusively with drinking water, which at all times can
freely circulate (a separately installed heat exchanger is mandatory for heating
saline water or corrosive water).
d. The tank is safeguarded against harmful scaling and lime build-up by means of
periodic maintenance.
e. The water temperatures in the heater do not exceed the maximum setting.
f. The water pressure and/or heat load do not exceed the maximum values stated
on the storage tank plate.
g. The storage tank is installed in a non-corrosive atmosphere or environment.
h. The storage tank is connected to a protected cold supply arrangement, which is:
approved by the relevant authority; with sufficient capacity for this purpose;
supplying a pressure no greater than the working pressure stated on the storage
tank; and where applicable by a likewise approved temperature and pressure
relief valve, fitted in accordance with installation instructions of A.O. Smith
applying to the specific model of storage tank, and further in compliance with the
government and local authority installation and building codes, rules and
regulations.
i. The storage tank is at all times fitted with cathodic protection. If sacrificial anodes
are used for this, these must be replaced and renewed when, and as soon as,
they are 60% or more consumed. When power anodes are used, it is important to
ensure that they continue to work properly.
