ABOUT YOUR WATER HEATER
11
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 solar cold pipes have been drained, it will be necessary to bleed
the collector circuit (refer to “Bleeding the Solar Collectors” on page 10).
If the electrical supply to the water heater has been switched off:
Switch on the electrical supply at the power outlet to the solar control unit. The power outlet must be
switched on for the solar control unit to operate and solar gain to be achieved.
Switch on the electrical supply at the isolating switch to the solar storage tank.
Check and if required reset the timer, if one is installed.
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are shown on pages 27 and 30. The water heater must be installed by an
authorised person and the installation must comply with Standards AS/NZS 3500.4, AS/NZS 3000 and all
local codes and regulatory authority requirements. In New Zealand, the installation must conform with
Clause G12 of the New Zealand Building Code.

DOES THE WATER CHEMISTRY AFFECT THE WATER HEATER?

detrimental effects on the cylinder, solar collectors and fittings. If you are in a known harsh water area you
must read page 14. If you are not sure, have your water chemistry checked against the conditions
described on page 14.
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 chemistry, the water pressure, temperature (inlet and outlet) and the water usage pattern.
However, your water heater is supported by a comprehensive warranty (refer to page 48).
GOING ON HOLIDAYS
If you plan to be away from home, conserve energy by switching the booster switch “OFF”. It is not
necessary to switch off the electrical supply at the power outlet to the solar control unit. Refer to “To Turn Off
The Water Heater” on page 10. Also if the system is not used for a period in excess of two (2) weeks it is
recommended the solar collectors be covered.
