INSTALLATION & MAINTENANCE - ALL SYSTEMS
REGULATIONS AND OCCUPATIONAL 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
WARNING
regulatory requirements 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
• Building Codes of Australia (BCA)
• Local Occupational Health and Safety (OH&S) regulations
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. Refer to the section 'INSTALLATION OF SOLAR
COLLECTORS' 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. Rinnai 'external' gas boosters are suitable for external installation
only.
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.
