System should be located and arranged so as to achieve the closest proximity to water draw off points.

Rinnai cylinders are manufactured to suit most NZ council water supplies. However some supplies can have a detrimental effect on the cylinder, its operation and life expectancy.  
Water supplies with a high level of calcium carbonate (hard water) can cause scaling on hot surfaces. We recommend a temperature of no more than 65 °C to minimise scale buildup. Scale reducing or water softening devices should be considered in hard water areas.  The unit is not guaranteed against damage due to scaling. For details of water quality please refer to the water quality parameters in the warranty.
