SECTION 1

HOT WATER CAN CAUSE SERIOUS INJURY

WARNING - Hot Water is dangerous! As a safety precaution, young children should always be

supervised around hot water fixtures

THIS WATER HEATER IS ONLY INTENDED TO BE OPERATED BY PERSONS WHO HAVE THE EXPERIENCE OR THE

KNOWLEDGE AND THE CAPABILITIES TO DO SO. THIS WATER HEATER IS NOT INTENDED TO BE OPERATED BY

PERSONS WITH REDUCED PHYSICAL, SENSORY OR MENTAL CAPABILITIES IE: THE INFIRM AND CHILDREN.

As solar water heaters can generate water temperature in excess of 80

solar rated tempering valve shall be installed in accordance with the valve manufacturer's instructions. This

is required to prevent water temperatures supplied to the house exceeding a preset safe maximum. The

tempering valve is connected to the hot water outlet lines. The valve must be fitted by an authorised plumber at

the time of installation or in retrofitting to existing systems.

CHECK THE WATER TEMPERATURE BEFORE USE, SUCH AS WHEN ENTERING A SHOWER OR FILLING A BATH OR

BASIN, TO ENSURE IT SUITABLE FOR THE APPLICATION AND WILL NOT CAUSE SCALD INJURY.

Hot water systems can store water at temperatures that can cause scalding. Water temperatures over 50

can scald and care needs to be taken to ensure that injuries do not occur through incorrect use of your water

heater.

THIS WATER HEATER USES 240V AC POWER FOR THE ELECTRICALLY OPERATED COMPONENTS.

THE REMOVAL OR ATTEMPTED ALTERATION OF ANY ELECTRICAL COMPONENT MUST BE CONDUCTED BY A

QUALIFIED ELECTRICAL SERVICE PERSON.

Care should be taken to avoid coming into contact with any pipe work or fixtures associated with the water

heater collector flow and return lines.

FOR CONTINUED SAFETY OF THIS APPLIANCE, IT MUST BE INSTALLED, OPERATED AND MAINTAINED IN

ACCORDANCE WITH THE MANUFACTURERS INSTRUCTIONS.

Water from the solar collectors can be hot enough to create pressurized steam which can cause severe scalding

- under NO circumstances should any alterations be made by unauthorised personnel.

IN ORDER TO KILL LEGIONELLA BACTERIA IT IS AN AUSTRALIAN STANDARDS REQUIREMENT (AS3498-2009) THAT

THE HOT WATER IN THE STORAGE TANK BE HEATED UP TO AT LEAST 60

IN THE STORAGE TANK (SOLAR / ELECTRIC) OR BY A POST BOOST SET AT 70°C (GAS CONTINUOUS FLOW).

Pressure Reduction Valve (PRV 500)

A pressure reduction valve of 500kPa maximum must be fitted immediately downstream of the cold water non-

return isolation valve. Failure to install a pressure reduction valve will void the warranty. Please note cold

water supply line to the tempering valve must be run after the PRV to ensure equal supply pressure to the

tempering valve.

Note: In SA, WA & QLD (and some other areas of other states subject to local authority regulations) it is a

requirement that an expansion control valve be fitted between the non-return isolating valve and the water

heater.
