• Manufacturer’s Installation Instructions
• Current AS/NZS 3500
• All applicable local rules and regulations including local OH&S requirements
This system must be installed, commissioned and serviced by an Authorised Person.
NOT SUITABLE AS A POOL OR SPA HEATER
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 pipe must not be used. Components used to
join pipes must use metallic materials to achieve sealing.

The Rinnai solar hot water warranty booklet species the locations and
conditions that apply for at plate collectors to be warranted against frost
damage.
In locations where the warranty booklet that frost valves must be used, they
must be tted for warranty to apply. Failure to t frost valves will void any
warranty against frost damage.
For full warranty terms, conditions and exclusions refer to the Rinnai
Warranty Booklet for solar hot water. The warranty booklet is available at

INSTALLATION INFORMATION
Rinnai 5 Split Collector IM
REGULATIONS AND OCCUPATION HEALTH AND SAFETY (OH&S)
Installation and commissioning must be performed by authorised persons. Rinnai solar systems must be installed
in accordance with these instructions and all 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 3500 National Plumbing and Drainage
• Building Codes of Australia
• Local Occupational Health and Safety (OH&S) regulations
WARNING
Solar collectors are heavy and bulky items and are usually positioned on the roofs of buildings. Each
Australian State and Territory has 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qualied,inaccordancewithlocalOH&Srequirements.
WATER QUALITY
The water quality of most public supplies is suitable for the water heating system. The water quality from bore wells
is generally unsuitable for the water heating system. Refer to separate ‘Warranty Terms and Conditions’ document
for water quality parameters and how they affect the warranty conditions. If in doubt about the water quality, have
it checked against the parameters listed in the warranty conditions. The system is not suitable as a pool or spa
heater.
SYSTEM ORIENTATION AND INCLINATION
The performance of any solar hot water system is determined by the way the system is installed.
For Australian installations, solar collectors should face the equator (True North) for optimum performance.
Installing solar collectors facing up to 45 degrees away from North (between North-East and North-West) will
reduceefciencybyapproximately5%.
For Australian installations the inclination of solar collectors should be the same as the latitude of the site for optimum
performance.Inclinationswithin20degreesofthelatitudeofthesitewillreduceefciencybyapproximately5%.
Most roofs in Australia have a slope of between 20° and 25° and provide an appropriately angled mounting surface.
Installersmustensuretheycomplywithrelevantlocalregulationsregardingsolarcollectorinclination
andorientation.

ROOF MOUNTING OPTIONS
Forroofswithaslopeof10°orlessaatroofframemustbeused.
Roof construction must be checked to ensure that the roof timbers are capable of supporting the additional load.
(Refer to AS 3500.4 Appendix H).
The roof mounting option must be appropriate for the wind loading that is likely in the installed location. See the
section 'Mounting Location Suitability' on page 7.

BuildingCodeofAustralia(BCA).Suchspecicationsrelatetothetypeoffastenings,thenumberoffasteningsand
their embedment into the building structure. They are determined from factors including the geographical location
and topography, the prevailing wind conditions, building dimensions, rooftop form and structural materials, and
the intended location of the solar panels relative to building internal, edge and corner zones. The BCA references
AS1170.2 “Structural Design Actions Part 2: Wind Actions”, AS3600 “Concrete Structures” and AS4100 “Steel
Structures”inrelationtothesespecications.

WATER PIPES AND FITTINGS
WARNING
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 pipe must not
be used. Components used to join pipes must use metallic materials to achieve sealing. The collector
owandreturnpipesshouldbe15mmcoppertube.
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 efciency. 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. With the exception
ofsolarcollectorowandreturnpipes,waterpipesizingshouldbeperformedinaccordancewithAS/NZS3500.
Thesuggestedmaximumcombinedlengthofthesolarowandreturnlinesis40metres.Pleaserrefertothe
systemsinstallationmanualsuppliedwiththepumpkitforthemaximumpipelengthforthespecicpipekit.
AllexternalpipeworkMUSTbeinsulatedtopreventfrostdamage.AllttingsMUSTbeinsulatedtoprotectfrom
frost damage, with the exception of the air bleed valve. .

WARNING
When connecting collectors or copper pipe with compression unions, ensure that the compression
union is held at 2 points as shown in the diagram. One side should be held still while the other is
tightened. Not doing this can cause damage to the collector or leaks.
WARNING
When connecting the collectors with compression unions, ensure that the collectors are pushed
together so that the olive is sitting approximately 15mm from the end of the copper pipe. This ensures
thejoinwillsurvivetheexpansionandcontractionthatcanoccurduetotemperatureuctuations.
