ABOUT YOUR WATER HEATER
12
TO TURN ON THE WATER HEATER
Open the cold water isolation valve fully at the inlet to the water heater.
If the solar collector(s) and solar hot and solar cold pipes have been drained, it will be necessary to
bleed the collector circuit (refer to “Bleeding the Solar Collector(s)” on page 11).
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
and for the anti-freeze heating unit to operate and offer additional freeze protection.
GOING ON HOLIDAYS
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 11. Also if the system is not used for a period in excess of 2 weeks it is
recommended the solar collector(s) be covered.
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are shown on pages 25 and 33. The water heater must be installed:
by a qualified person, and
in accordance with the installation instructions, and
in compliance with Standards AS/NZS 3500.4, AS/NZS 3000, AS 5601 or AS/NZS 5601.1, as applicable
under local regulations, and all local codes and regulatory authority requirements.
In New Zealand, the installation must also conform with NZS 5261, as applicable under local regulations, and
Clause G12 of the New Zealand Building Code.
Warning: Temperature controllers must not be fitted to the in-series water heater as part of a solar water
heater system because water at a temperature much higher than the controller setting can be delivered.
