IMPORTANT INFORMATION
GENERAL
The information contained in this guide, and all other information or advice given at any time by
Rheem New Zealand Limited in connection with the purchase, installation or use of a Rheem water
heater, is given in good faith. Subject to any rights the owner may have under the “Consumer
Guarantees Act 1993”, Rheem New Zealand Limited will not be liable to any person for any inaccuracy
or omission in the information or advice arising through the fault or negligence of Rheem New Zealand
Limited or any other person or through any other cause whatsoever.
This water heater is designed for use in a single family domestic dwelling for the purpose of heating
potable water. Its use in an application other than this may shorten its life.
Warning: This water heater is only intended to be operated by persons who have the experience
or knowledge and capabilities to do so. This water heater is not intended to be operated by
persons with reduced physical, sensory or mental capabilities i.e. the infirm, or by children.
ABOUT YOUR WATER HEATER
DOES THE WATER QUALITY AFFECT THE WATER HEATER?
Your water heater is suitable for most public water supplies, however, some water qualities may have
a detrimental effect on it. If you are in a known harsh water area please read page 9.
HOW HOT SHOULD THE WATER BE?
For reasons of safety and economy, we recommend the thermostat is adjusted to the lowest setting
that meets your needs. Some models require an authorised person to make any temperature
adjustments. The New Zealand Building Code requires a temperature setting of not less than 60°C
within the tank to protect against Legionella.
Regulations require an approved temperature limiting device (tempering valve) be fitted into the hot
water pipe work to the bathroom(s) and ensuite(s) to provide safety protection from potential scalding.
This will keep the hot water supply temperature to the bathroom(s) and ensuite(s) below 55°C which
will reduce the risk of scald injury whilst still allowing hotter water (60°C+) to the kitchen and laundry.
To minimise scalding, especially for those people in high scald risk categories i.e. young children,
people with potentially incapacitating medical conditions, elderly people etc, this water heater must be
installed in accordance with AS/NZS 3500.4.
Water temperatures within the tank of 90°C or higher are possible if the water heater is connected to
solar panels or any other secondary sources (refer page 7).
Warning: This water heater can deliver water at temperatures which can cause scalding. Always
check the water temperature before use, such as when entering a shower or filling a bath or basin,
to ensure it is suitable for the application and will not cause a scald injury.
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Refer to the installation requirements on page 6.
HOW LONG WILL THE WATER HEATER LAST?
There are a number of factors that affect the life of the water heater. These include; the water quality,
water pressure, water temperature and the usage pattern, however, your Rheem water heater is
supported by a comprehensive warranty (refer to page 8).
