ABOUT YOUR WATER HEATER
7
TO TURN ON THE WATER HEATER
• Open the cold water isolation valve fully on the cold water line to the water
heater.
• Plug in the power supply cord at the power outlet (power supply cord model
only).
• Switch on the electrical supply at the isolating switch to the water heater.
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are shown on pages 15 to 21. The water heater must
be installed by an authorised person and the installation must comply with
National Standards AS/NZS 3500.4, AS/NZS 3000 and all local codes and
regulatory authority requirements. In New Zealand the installation must
conform with the New Zealand Building Code.
DOES THE WATER QUALITY AFFECT THE WATER HEATER?
The water heater is suitable for most public water supplies, however some
water qualities may have detrimental effects on the cylinder and fittings. If you
are in a known harsh water area
you must read page 33. If you are not sure,
have your water quality checked against the conditions described on page 33.
HOW LONG WILL THE WATER HEATER LAST?
There are a number of factors that will affect the length of service the water
heater will provide. These include the water quality, the water pressure, the
water temperature (inlet and outlet) and the water usage pattern. However,
your Rheem water heater is supported by a comprehensive warranty
(refer to
page 36 ) .
ANODE PROTECTION
The anode(s) installed in your water heater will slowly dissipate whilst
protecting the cylinder. The life of the water heater cylinder may be extended
by arranging for an authorised person to inspect the anode(s) and replace if
required.
The suggested time after installation when the anode(s) should be inspected is:
Rheemglas 8
years
RheemPlus 8 years
Optima 10 years
For softened water supplies or in areas of poor water quality, it is
recommended the anode(s) be inspected 3 years earlier than shown (refer to
“Water Supplies” on page 33).
