WATER QUALITY
All Dux 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 Dux 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 will 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 Dux warranty would not apply.
