Water chemistry and impurity limits are detailed under 'Warranty Conditions'. Most metropolitan water supplies fall
within the requirements.
If you are unsure about your local water quality, contact your water authority. If sludge or foreign matter is present
in the water supply, a suitable filter or strainer is required in the water supply to the water heater to prevent
unwarranted damage and loss of performance.

Local regulations and or the requirements of AS/NZS 3500 MUST BE addressed regarding the temperature
limitations of hot water supplied to areas used primarily for personal hygiene. The temperature of water to these
areas may be limited to 50°C or less.
To ensure these regulations and or requirements are met the system MUST BE installed in accordance with the
"Installation Configurations" detailed below.

1 below. If you are unsure about your local regulations contact your regulating authority or Rinnai.
If the appliance is NOT marked to state that it delivers water not exceeding 50°C, or your local regulations require
installation with a Temperature Limiting Device then install the appliance in accordance with Diagram 2 below.
