INSTALLATION – SOLAR STORAGE TANK

Victorian Installers

Notice to Victorian Installers from the Victorian Plumbing Industry Commission if this solar water heater is

installed in a new Class 1 dwelling in the State of Victoria. The system model number is to be recorded on

the Certificate of Compliance. It is also a requirement to provide the householder with permanent

documentation recording the system model number exactly as it is shown in the „List of systems capable of

complying with the regulations‟ published by Sustainability Victoria (see www.sustainability.vic.gov.au). This

documentation may be in the form of an indelible label adhered to the solar storage tank, or other suitable

form placed in an accessible location, such as the meter box, for later inspection.

WATER HEATER APPLICATION

This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable

water. Its use in an application other than this may shorten its life.

If this water heater is to be used where an uninterrupted hot water supply is necessary for the application or

business, then there should be redundancy within the hot water system design. This should ensure the

continuity of hot water supply in the event that this water heater was to become inoperable for any reason.

We recommend you provide advice to the system owner about their needs and building backup redundancy

into the hot water supply system.

Note: AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in

potable water. This water heater has an in-series gas booster which can satisfy this AS 3498 requirement

provided the gas booster is energised, the booster preset outlet temperature setting is 70°C or higher and a

remote temperature controller is not used.

SOLAR WATER HEATER STORAGE TANK LOCATION

The solar storage tank is suitable for outdoor installation only. The solar storage tank should be installed

close to the most frequently used outlet and its position chosen with safety and service in mind. Make sure

people (particularly children) will not touch the flue terminal. The flue terminal and air inlet must be clear of

obstructions and shrubbery.

Consideration must also be given to the position of the solar storage tank in relation to the solar collectors.

There are limitations on both the maximum length of the solar hot and solar cold pipes and the maximum

height between the solar storage tank and the solar collectors. Refer to “Solar Collector Location” on page 29

and to “Pipe Lengths” on page 30.

Clearance must be allowed for servicing of the solar

storage tank and gas booster. The solar storage tank must

be accessible without the use of a ladder or scaffold. Make

sure the temperature pressure relief valve lever is

accessible and the front panel and front covers can be

removed for service.

You must be able to read the information on the rating

plate. If possible leave headroom of one water heater

height so the anode can be inspected or replaced.

Remember you may have to remove the entire solar

storage tank later for servicing.

It is recommended the solar storage tank be installed at

ground or floor level and must stand vertically upright.

Note: It is important for the solar storage tank to be orientated vertically upright in order for the falling film of

closed circuit fluid to operate efficiently.

The top of the solar storage tank must be a minimum of 500 mm below the bottom of the solar collectors for

the system to operate correctly.

The water heater must not be installed in an area with a corrosive atmosphere where chemicals are stored or

where aerosol propellants are released. Remember the air may be safe to breathe, but when it goes through

a flame, chemical changes take place which may attack the water heater.

A secondary flue is not required. The water heater must not be installed indoors or in a confined space.
