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
WARNING
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. For
tiled roofs, 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 - Solar Collectors' on page 12 for more information.
NOT SUITABLE FOR USE IN CYCLONE AREAS.
WARNING
HI RISE KITS IN CONJUNCTION WITH SPLIT SYSTEM FLAT ROOF FRAMES
For buildings higher than 10 metres additional collector mounting components must be used to secure the collector
to the rail/frame. See the section 'Collector Mounting Rail Pre Assembly' on page 15 for full details. For buildings
higher than 10 metres using a flat roof frame, the mounting of the frame to the roof must be carried out in accordance
with the instructions "Installation Manual - Rinnai Commercial High Rise Kit".
WATER PIPES AND SUPPLY
The solar hot and solar cold pipes between the solar storage tank and the solar collectors
must be suited to the high water temperatures and pressures that may occur. As such, plastic
WARNING
pipe must not be used. Components used to join pipes must use metallic materials to achieve
sealing.
Capillary silver solder is a suitable joining method.
All hot water pipework should be insulated with sealed polyethylene foamed or equivalent insulation to optimise
performance and energy efficiency. Such insulation may also be mandatory under local regulations. Rinnai
recommend insulation to achieve an R value of 0.6 K.m2/W or higher depending on location. All external pipework
MUST be insulated to prevent frost damage.
