This Installation Manual has been prepared for qualified
installers of the hot water system. Please keep in a safe place for
future reference. Installation must be performed by a qualified
installer (for example, a licensed plumber or gas fitter).
warning
For continued safety of this appliance it must be installed,
operated and maintained in accordance with the
manufacturers instructions.
For the installer
The installation must be done in accordance with the
information supplied in this Installation Manual.
For gas boosted installations, please refer to Warnings and
Cautions in the Gas Continuous Flow installation manual
supplied with the unit. All other relevant National, State or
Local regulations must also be conformed with and these
include (but are not limited to):
• Australian Standard AS3500.1 – Water Supply
• Australian Standard AS3500.4 – Hot Water Supply
• Australian Standard AS3000 – Electrical Installation
• Australian Gas Association Code AS5601 –
Gas Appliance Installation
• Local Water, Gas & Electrical Authority Regulations
Municipal Building Codes
Important safety instructions
Ensure the following safety instructions are read and
understood before commencing installation.
warning
If you do not follow these instructions exactly, a fire or
explosion may result causing property damage, personal
injury or loss of life.
• This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities or lack of experience and knowledge, unless
they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not
play with the appliance.
• If the solar hot water system is gas boosted and you smell
gas or smoke coming from the system:
– Do not try to light the hot water system.
– Do not touch any electrical switch
– Do not use any phone in your building
– Isolate the power at the main switchboard
– Check and isolate the main gas valve
– Immediately call your gas supplier from a neighbour's
phone. Follow the gas supplier's instructions
– If you cannot reach the gas supplier, call the
fire department
• The piping system of the solar circuit is to be electrically
connected in the lower part of the building according to
local standards. The connection of the solar system to
an existing or to be created lightning protection system
or potential equalization may be implemented only by
authorised specialists.
• If the solar hot water system is gas boosted, ensure there
is proper ventilation to avoid oxygen deficiency.
• Ensure that any water drained during installation does
not cause damage to the building or property.
• Be sure that the hot water system is well earthed in
order to avoid electric shock.
• The solar hot and solar cold pipes between the hot water
storage tank and solar collectors MUST BE copper
and fully insulated with closed cell polymer insulation
or similar (minimum thickness of 20mm). Thicker insulation
may be required to comply with the requirements of
AS/NZS 3500.4. Plastic pipe MUST NOT be used, as it
will not withstand the temperature and pressure of the
water generated by the solar collectors under stagnation
conditions. The solar collectors can generate extremely
high water temperatures of up to 272°C. Plastic pipe can
not withstand these temperatures. Failure of plastic pipes
can lead to the release of high temperature water
and cause severe water damage and flooding.
• The insulation must be weatherproof and UV resistant if
exposed to sunlight.
• All compression fittings must use brass or copper olives.
• The collectors must be filled with water before the
protective cover is removed to prevent damage to the
hot water system and harm to the installer.
• Ensure that the roof has the load bearing capacity
to withstand the weight of installation, including the
installers and the full collectors.
• Installation must be carried out in accordance with
local Occupational Health and Safety laws.
• Ensure that appropriate safety measures are taken to
prevent objects falling from the roof during installation.
• The standard roof mounting kit for the collectors supplied
with this unit is NOT suitable for cyclone prone areas.
If you are installing in a cyclone prone area, please
consult your local building authority for advice regarding
appropriate mounting requirements.
• The minimum inlet water pressure must be 150kPa.
• If the hot water system supply pressure exceeds 600kPa, a
pressure limiting valve must be fitted to limit the pressure
to 600kPa. A cold water 700kPa pressure relief valve may
also need to be installed in the water inlet to the storage
tank according to local regulations.
• A 99°C/850kPa temperature and pressure relief valve
(supplied) must be installed near the top of the storage tank.
• Ensure that the discharge pipes of the pressure relief
valves are left open to the atmosphere at all times.
• The pressure-relief devices are to be operated regularly to
remove lime deposits and to verify that they are not blocked.
• If a supply cord is damaged, it must be replaced by the
manufacturer, its service agent or qualified persons in
order to avoid a hazard.
• The operation of the thermal cut-out on the hot water
storage tank indicates a possibly dangerous situation
(electric boosted installations only). Do not reset the
thermal cut-out until the hot water system has been
serviced by a qualified person.
• Solar hot water systems with flat panel type collectors
are not designed to be installed in heavy frost or high
altitude areas 400m above sea level.
• This hot water system delivers water above 50°C
and a tempering valve must be installed to limit the
temperature of hot water to sanitary fixtures primarily
used for the purpose of personal hygiene as per the
AS 3500 requirements.
• The temperature settings for the hot water system are
factory pre-set to ensure optimum energy efficiency
whilst providing Legionella bacteria protection. The
temperature settings are therefore not adjustable by
the customer or installer.
