TO TURN OFF THE WATER HEATER
If it is necessary to turn off the water heater:
•
Shut down the gas control (refer to
•
Close the gas isolation valve at the inlet to the gas control.
•
Switch off the electrical supply at the isolating switch to the water heater (refer to note below).
•
Close the cold water isolation valve at the inlet to the water heater.
Note: If there is a risk of freezing conditions, the electrical supply to the solar control unit should not be
switched off unless the solar collectors are drained, otherwise damage could result (refer to
Protection" on page 9).
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
•
If the electrical supply to the water heater has been switched off, switch on the electrical supply at
the isolating switch. The isolating switch must be switched on for the solar control unit to operate
and solar gain to be achieved.
•
Open the gas isolation valve fully at the inlet to the gas control.
•
Light the water heater (refer to
•
Ensure the timer is programmed (refer to
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are
person and the installation must comply with National Standards AS/NZS 3500.4, AS/NZS 3000,
AS 5601 and all local codes and regulatory authority requirements. In New Zealand, the installation
must conform with the Code of Practice for installation of Gas Appliances NZS 5261 and the New
Zealand Building Code. The timer is not weatherproof and must be installed indoors.
PIPE WORK AND INSULATION
The solar hot and solar cold pipe work between the solar storage tank and the solar collectors
MUST BE of copper and fully insulated with closed cell polymer insulation or similar (minimum
thickness 13 mm). The insulation must be weatherproof and UV resistant if exposed. The insulation is
essential to assist in providing freeze protection, will offer corrosion protection to a metal roof against
water runoff over the copper pipe, assist in avoiding accidental contact with the solar pipe work and
also reduce pipe heat losses.
The insulation must be fitted up to the connections on both the solar collectors and the solar storage
tank, as very high temperature water can flow from the solar collectors to the solar storage tank under
certain conditions.
Plastic pipe MUST NOT be used, as it will not withstand the temperature and pressure of the water
generated by the solar collectors under certain conditions
