ABOUT YOUR WATER HEATER

TO TURN ON THE WATER HEATER
· Open the cold water isolation valve fully at the inlet to the water heater.
· If the solar collectors and solar hot and cold pipes have been drained, it will be
necessary to bleed the collector circuit (refer to “Bleeding the Solar Collectors”
on page 7).
If the electrical supply to the water heater has been switched off:
Switch on the electrical supply to the solar storage tank at the isolating switch
Switch on the electrical supply to the solar control unit at the power outlet.
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are shown on pages 23 and 26. The water heater must be
installed by an authorised person and the installation must comply with national
codes AS/NZS 3500.4.2, AS/NZS 3000, and all local codes and regulatory authority
requirements. In New Zealand, the installation must conform with the New Zealand
Building Code.
Note: The solar hot and cold pipe work between the solar storage tank and the
solar collectors
must be
of copper and fully insulated with Armaflex insulation or
similar (minimum thickness 10 mm). The insulation must be weatherproof if
exposed and fitted up to the connections on the storage tank, as very high
temperature water can flow from the solar collectors to the storage tank under
certain conditions. Plastic pipe
must not
be used, as it will not withstand the
temperature of the water generated by the solar collectors under certain conditions
(refer to Warning on page 29).
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, solar collectors and fittings. If
you are in a known harsh water area you must read page 38. If you are not
sure, have your water quality checked against the conditions described on page 38.
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 (refer to page 40).
