This appliance is not suitable for use as a domestic spa pool or swimming pool heater�
Solar collectors and cylinders 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.

system location
These systems are only suitable for use on buildings up to 10 metres tall�
WARNING
Select suitable areas of roof on which to install the solar collectors and cylinder� It is essential that the roof structure
is suitable for the solar collector/cylinder combination and can support the weight of these items when full of water.
It is the installers responsibility to ensure the roof can safely support the system and to visually check the roof,
and if there is any damage that requires attention (such as cracked tiles etc�), to inform the owner� If this affects
the safe installation of any part of the system, installation should not proceed until the damage has been rectified.
Collectors should be positioned for optimum solar benefit. Refer to the section 'System Orientation and Inclination'
on page 21 for more information�
All system components must be in an accessible location. Sufficient clearances shall allow access to, and removal
of, all serviceable parts. Ensure the PTR valve, drain lines, thermostats and elements have sufficient clearances
and are accessible for service and removal� The information on any data plates must also be readable�
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�
gas booster location (where applicable)
The S20, S26 and S32 gas boosters are designed for 'Outdoor' Installation only� As such, they must be located in
an above ground open air situation with natural ventilation, without stagnant areas, where gas leakage & products
of combustion are rapidly dispersed by wind and natural convection� If an internal model which has been converted
to a solar gas booster follow information supplied with the unit for location, mounting and flueing requirements.

WaTeR pIpes

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. With the exception of
solar collector flow and return pipes, water pipe sizing should be performed in accordance with AS/NZS 3500. All
external pipework MUST be insulated to prevent frost damage�
