Most metropolitan water supplies fall within these limits. If you are unsure about water quality,
please contact rinnai and we will provide you with the details of an authorised agency able to
test your water for compliance to rinnai standards. If sludge or foreign matter is present in
the water supply, a suitable filter should be incorporated in the water supply.
Some examples of water quality issues where water may need to be treated:
Hard water (areas including Wanganui)
aggressive water (areas including Christchurch)
Both hard and aggressive water (some bore water)
E-Frost collectors are warranted against frost damage caused by temperatures down to and
including -15 °C where power is available to the system and the system is configured for low
temperature mode (factory default).
It is conditional that power is available and switched on. Failure due to lack of power supply or
changes to the temperature mode settings are not covered.
