SAFETY INFORMATION
WARNING – OCCUPATIONAL HEALTH & SAFETY INFORMATION
Solar hot water systems can be heavy so always use approved lifting devices when installing a solar
systems. You MUST adhere to all Occupational Health and Safety requirements
WARNING – ONLY USE COPPER PIPES AND APPROVED COPPER FITTINGS. PLASTIC PIPES MUST
NOT BE USED IN THE INSTALLATION OF THE SOLAR HOT WATER SYSTEM
It is a requirement of a solar water heater installation that all pipe work be in copper and not plastic,
due to the effects of high water temperatures and pressures
WARNING – HOT WATER BURNS
Solar water heaters can generate water temperatures > 85°C, therefore, a tempering valve, or ap-
proved ‘mixing valve’ MUST be fitted to prevent water temperatures going to the home exceeding a
preset safe maximum. As a safety precaution, young children should always be supervised around
hot water fixtures as water temperatures over 50 degrees Celcius can cause scalding. Liquid from
the solar panels can be hot enough to create pressurized steam which can cause severe scalding. NO
MODIFICATIONS SHOULD BE ATTEMPTED by the homeowner. All work on the solar collectors, tank
or associated pipe work MUST be carried out by a licensed, authorized person
WARNING –
INSTALLERS MUST exercise extreme care when installing or working on solar systems.
Our recommend solar panels are ALWAYS covered during installation
WARNING –
It is a mandatory requirement of Australian Standard AS/NZS3500.4.2 that a suitably
approved temperature control device be fitted to the hot water supply for outlets used primarily for
personal hygiene. This valve should be checked regularly to ensure its operation and settings remain
correct. ALL systems must be installed with a Tempering valve
WARNING – DANGEROUS HYDROGEN GAS BUILD UP
If the hot water system is not used for a week or more, an amount of very flammable hydrogen gas
may accumulate in the tank. To dissipate this gas in a safe manner, it is recommended that a hot
water tap is turned on for a few minutes or until discharge of the gas stops. A sink or bath MUST be
used for this procedure, not an appliance such as a washing machine or a dishwasher. During this
procedure there should be no open flames, no smoking and no operation of an electrical appliance
nearby.
WARNING – TPR VALVE MUST BE FITTED
The temperature/pressure relief safety valve ( 1000 kPa ) supplied MUST be fitted to the top of each
storage cylinder with a permanently open copper discharge pipe angled downwards in a frost free en-
vironment. The valve MUST be operated every 6 months to remove any lime deposits and verify there
are no blockages. NOTE water may drip from this pipe during normal operation.
