Installer’s Guide
Full and detailed installation instructions
are in the Installer’s Guide, included
inside the water heater’s carton.
Location
The water heater should be located as
close as possible to the most frequently
used hot water outlet. Ensure that the
data plate is clearly visible and provide
adequate access for service to the
thermostat, relief valve and anode.
Note: All models are equipped with a
sacricial anode, accessible through the
top cover. Allow 50% of the height of
the water heater for clearance above to
replace the anode.
We recommend a plinth be installed
under the water heater where the
water heater is subjected to wet
conditions
A properly drained overow tray must
be used where property damage could
occur from water spillage. (See AS/
NZS3500.4 for further details.)
Note: Warranty does not cover
consequential damage due to heater
leakage.
Safety
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 and animals should be
supervised to ensure that they do not
interfere with the appliance.

Frost Protection
Consult the table right to determine if
your system needs an anti-frost valve.
If your model does require frost
protection, you must install an anti-frost
valve.
However, TWO anti-frost valves must
be installed if you live in alpine areas or
areas subject to extreme frost, such as
the ACT and Snowy Mountain regions.
The anti-frost valve comes in kit form
and must be ordered seperately.

Installation Requirements
This water heater must be installed
by a licensed tradesperson, and in
accordance with:
• AS/NZS3500.4 “National Plumbing
and Drainage Code Hot Water
Supply Systems – Acceptable
Solutions”.
• Clause G12 of the New Zealand
building code.
• Local authority regulations.
• Outside Australia and New Zealand,
please refer to local plumbing and
building codes and regulations.
• Notice to Victorian customers from
the Victorian Plumbing Industry
Commission – this water heater must
be installed by a licensed person as
required by the Victorian Building Act
(1993). Only a licensed person will
give you a compliance certicate,
showing that the work complies with
all the relevant Standards and only a
licensed person will have insurance
protecting their workmanship for 6
years.
Water Supply Pressure
This water heater is designed for direct
connection to water supply pressures of
no greater than:
All Models – 800kPa
Where the mains pressure can exceed
or uctuate beyond the pressure shown
above, a pressure limiting device
(complying with AS1357) must be tted
in the cold water inlet supply. This device
must be installed after the isolating
valve and set below the pressure shown
above. Note during periods of lower
demand water pressure may increase.
Pool Heating
This water heater must not be used for
pool heating.
Pressure & Temperature Relief
Valve
The Pressure & Temperature Relief Valve
is supplied loose with the water heater.
The valve rating is:
All Models – 1000kPa
The PTR valve must be installed directly
into the top socket marked “RELIEF
VALVE”. The drain line from this valve
must run in a continuously downward
direction in a frost-free ambient position
with the discharge end left open to
atmosphere permanently.
The PTR Valve is not intended to enable
connection of the water heater to
supplementary energy sources such as
solar panels or slow combustion stoves
(refer AS/NZS 3500.4 for guidance on
these types of installations).
Open the PTR Valve for approximately
10 seconds by lifting the lever on the
valve to ensure water is relieved to waste
through the relief drain pipe. Lower lever
gently and check that it closes correctly.
Plumbing Connections

H3161 025248 Rev. D
The PTR Valve must not be tampered
with or removed. The water heater must
not be operated unless this valve is
tted and in working order.
The PTR Valve should be checked for
adequate performance or replaced at
intervals not exceeding 5 years, or less
in areas where local regulations apply.
Important: The PTR Valve and its
drain outlet pipe must not be sealed or
blocked. It is normal for the PTR valve
to leak a small amount of water during
heating cycles.
Danger
Failure to operate the relief valve easing
lever at least once every six (6) months
may result in a problem with the water
heater and in some cases the tank may
explode.
Warning: A separate drain line must be
run for this relief valve. It is not permitted
to couple drain lines from relief valves
into a single common drain line.
Cold Water Connection
An approved isolating valve, non
return valve, line strainer (optional but
recommended), and union must be
tted between the supply main and the
RP¾"/20mm T tting connected to the
socket in the water heater.
All ttings must be approved by the
relevant Authority and in accordance to
the plumbing code.

Hot Water Connection
The hot water line should be connected
to the “OUTLET” socket on the tank.
Note: Once all connections have been
properly made, ll tank by opening
the cold water inlet and bleed all lines
according to appropriate plumbing code.
Safety Information
For safe performance this water heater
is tted with:
• an over-temperature energy cut-out
thermostat
• a combination Pressure &
Temperature Relief Valve.
These devices must not be tampered
with or removed. The water heater must
not be operated unless both of these
devices are tted and in working order.
The element cover should be removed
only by a qualied electrician. The
electrical power supply must be
isolated at the main electrical supply
switchboard before the water heater
electrical cover is removed.
Insulation of Pipes
All hot water pipes must be insulated
with UV stabilized insulation suitable
for solar working temperatures, e.g.
Armaex Insulation. Please check local
regulations regarding the use of hot
water supply pipework other than pipes
made of copper.
Temperature Protection
All solar water heaters have the
ability to produce hot water very
quickly. To reduce the risk of scald
injury, it is mandatory under the
requirements of Australian Standard
AS/NZS3500.4:2003 that a suitably
approved temperature control device be
tted to the hot water supply to outlets
used primarily for personal hygiene.
This valve should be checked at regular
intervals to ensure its operation and
settings remain correct.
Note: This water heater is supplied
with a tempering valve. Install the
valve according to the manufacturer’s
recommendations. Any adustments to
the valve should be made according to
the manufacturer’s recommendations.
The tempering valve should be checked
at regular intervals to ensure its
operation and settings remain correct.

Installer’s Guide
Full installation instructions for the
collectors are in the Installer’s Guide,
included inside the water heater’s carton.
Safety
Do not commence an installation until
you have satised yourself that all safety
issues associated with working on and
lifting components onto a roof have
been addressed.
Local Authority Regulations
All work associated with the installation
must comply with local authority
regulations, including AS/NZS 3500.4.2.
Where these installation instructions and
local regulations are in conict, local
regulations must prevail.
Location of Collectors
There are several factors to consider in
selecting the collector location site:
• For best performance, the collectors
need to face true north. Due to the
high solar energy levels experienced
in Australia, installations on angles
of up to 45° away from true
north should not have a major
effect on the annual solar output.
Consequently, installations up
to 45° away from true north
are acceptable. See Collector
Orientation Compass on page 9.
• If the collectors are installed with an
east facing bias, the best solar input
is achieved in the morning and if
there is a west facing bias, the best
solar input is in the afternoon.
• The collectors should be installed
with a minimum inclination of 10°
and a maximum inclination of
45°. See Collector Inclination Guide
on page 9.
• Careful site inspection is required to
ensure the selected location is not
subjected to shading from adjacent
trees or buildings at any time of the
day, but particularly between 9am
and 3pm, the highest solar input
times.
• Remember that shadows are longer
in winter than in summer, so a
site that is free of shadows from
adjacent objects in summer may
have some shadows in winter.
• To optimise efciency, the collectors
should be as close as possible to
the storage tank.
• For best performance, the collectors
should be located no more than
20m from the storage tank.
• Ensure that the roof structure is
suitable to support the weight of
the collectors. The collectors weigh
approximately 40kg each when full.
