10 Water quality
All Bosch water heating appliances are constructed from
high quality materials and components and all are
certified for compliance with relevant parts of Australian
and New Zealand gas, electrical and water standards.
Whilst Bosch water heaters are warranted against
defects, the warranty is conditional upon correct
installation and use, in accordance with detailed
instructions provided with the heater. In the case of the
water supplied to the heater, it is important that the
water quality be of acceptable standard.
The water quality limits/parameters listed in water
quality table are considered acceptable and generally,
Australian and New Zealand suburban water supplies fall
within these limits/parameters.
In areas of Australia and New Zealand where water may
be supplied, either fully or partly, from bores, artesian
wells or similar, one or more of the important limits may
well be exceeded and the heater could, therefore, be at
risk of failure.
Where uncertainty exists concerning water quality,
intending appliance users should seek a water analysis
from the water supplying authority and in cases where it
is established that the water supply does not meet the
quality requirements of the water quality table, the
Bosch warranty would not apply.
