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,
temperature (inlet and outlet) and the water usage pattern. However, your
Rheem water heater is supported by a comprehensive warranty
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
8 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
FREEZE PROTECTION
The solar circuit must be installed with a continuous fall in the pipe work from
the solar collectors to the solar storage tank, the solar hot and solar cold pipes
must be fully insulated with closed cell polymer insulation (minimum thickness
13 mm) and the system charged with correctly mixed closed circuit fluid to offer
protection against freeze damage. The system has NO WARRANTY for freeze
damage if there is not a continuous fall in the solar hot and solar cold pipes, or
they are uninsulated, or the closed circuit fluid has been incorrectly mixed (refer
to
on page 79 and to
on
page 7).
The anti freeze control of the solar circuit is designed so there is no closed
circuit fluid in the solar collectors or solar cold and solar hot pipes when the
pump is off.
Notes:
•
Pipe work to and from the water heater must be adequately insulated to
prevent freezing.
•
The water heater is not suitable for installation in areas where the ambient
temperature falls below -20ºC.
