INSTALLATION - ALL SYSTEMS

REGULATIONS AND OCCUPATION HEALTH AND SAFETY (OH&S)
Installation and commissioning must be performed by authorised persons.
Solar systems must be installed in accordance with these instructions and all regulatory requirements
WARNING
which exist in your area including those in relation to manual lifting, working at heights and on roofs.
Applicable publications and regulations may include:
•
AS/NZS 5601 Gas Installations
•
AS/NZS 3500 National Plumbing and Drainage
•
AS/NZS 3000 Wiring rules

This appliance is not suitable for use as a domestic spa pool or swimming pool heater.
Solar collectors are heavy and bulky items and are usually positioned on the roofs of buildings.
Australian State and Territories have a principal Occupational Health and Safety (OH&S) Act which
contains requirements relating to the handling of large, bulky or awkward items and the prevention of
falls from elevated surfaces. Persons installing solar collectors must be aware of their responsibilities
and be adequately trained and qualified, in accordance with local OH&S requirements.

LOCATION - GENERAL INFORMATION

All system components must be in an accessible location. The storage cylinder must be accessible without the use
of a ladder or scaffold. Sufficient clearances shall allow access to, and removal of, all serviceable parts. Ensure the
PTR valve, pump kit, drain lines and thermostat and elements for electric systems have sufficient clearances and
are accessible for service and removal. The information on any data plates must also be readable. In the case of
vitreous enamel lined cylinders, leave a clearance of the height of one storage cylinder above the cylinder being
installed so the sacrificial anode can be inspected and replaced. This does not apply to stainless steel cylinders.
Select suitable areas of roof on which to install the solar collectors as close as practicable to the cylinder. Ensure
that the area is even and without cracked or damaged tiles. Collectors should be positioned for optimum solar
benefit, and to minimise wind loading. Refer to the section 'Installation - Solar Collectors' on page 25 for more
information.
The solar pump kit and gas booster heater require an AC 240V power supply. A weatherproof 240V, 10A earthed
power point must therefore be provided adjacent to these.
All electrically boosted solar hot water heating elements must be connected to an independent, fused, AC 240V 50
Hz power supply with an isolating switch installed at the switch board.

STORAGE CYLINDER LOCATION

The storage cylinder should be placed as close as practicable to the most frequently used hot water outlet point or
points to minimise the delay time for hot water delivery. This will usually be the kitchen tap.
The solar storage cylinders have an ingress protection rating of IPX4 making them suitable for internal or external
installation.
Storage cylinders must be installed in freestanding mode on a level and stable base. For external installations,
storage cylinders should be mounted on a concrete base at least 50mm thick or on well seasoned, evenly spread
hardwood slats with a thickness of at least 25mm. Where property damage can occur, storage cylinders should be
installed with an approved safe tray (overflow tray).
Ensure the cylinder does not stand on wet surfaces.
