Installer’s Guide
• This Installer’s Guide and the
Owner’s Manual (also included in the
product carton) contain important
information about installation and use
of this water heater.
Note: For an easier
installation, please read this
document before you begin.
• Arrive at site, park vehicle as close as
allowable to installation, and conduct
a safety audit, also known as Work
Method Statements (WMS) or Job
Site Analysis (JSA).
• Prior to working at heights, it is the
responsibility of the installer to ensure
that all practices are compliant with
any relevant OH&S legislation.
Note: Do not commence a
job where the risks cannot be
controlled.
• Refer to local working at heights
regulations. NSW Ref: “Safe Work on
Roofs – Part 2 Residential” Code of
Practice 2004, Work Cover NSW.

• The existing tank (if applicable)
should be drained and removed in a
responsible manner.
Note: Do not drain on to grass
or garden beds.
• Safely position new storage tank on
a level surface in accordance with all
plumbing and building regulations.
Note: We recommend a plinth
be installed under the water
heater where the water heater
is subjected to wet conditions.
• Refer to the section called “Rough
In Diagram” on page 1 for detailed
information on position of plumbing.
Install a plinth under the
water heater where the
water heater is subjected

• Using correct plumbing methods,
connect the cold water pipe to the
storage tank.
• According to local regulations and
the plumbing code, t any and
all valves that are necessary e.g.
tempering valves, pressure limiting
valves, line strainer, duo valves, cold
water expansion valves etc.
• We recommend the use of new valves
for all Installation. Refer to plumbing
code and/or local requirements.
• Connect the supplied hose from
the top left tank outlet to the heat
exchanger water inlet.

Critical: Due to the high
temperature imposed by solar
heated water, all solar system
pipes and ttings must be DR
brass and copper, including
collector compression ttings
(as supplied). No plastic pipes
or ttings.
• Flow and return lines must be
installed as direct as possible
between tank and collector.
• Pipes must be fully insulated with
UV stabilized insulation suitable for
solar working temperatures. We
recommend Armaex DuoSolar /
Solar insulation, minimum 13mm
thick (refer to local regulations).
Note: Warranty will be void
if this minimum insulation
requirement is not used.
Pipes must be DR
brass and copper.
Refer to AS/NZS
3500.4.

• It is critical to stop any chance of an
air lock developing, so ensure that:
– no pipework is higher than the
automatic air vent valve
– ow and return pipes from the solar
collectors to the water storage tank
have a minimum of 5° continuous fall
– pipes have no high points that
allow air to be trapped
– the minimum number of bends in
the pipes are used.
• Flow and return lines should be
neatly installed and hidden inside the
roof cavity if possible.
• Take care when running ow
and return lines through the roof,
cladding and the eaves.
Note: Where roof and
the eaves are made from
asbestos, specialised handling
and advice is necessary.

Solar Collector Alignment
• For the most efcient solar gain, the
collectors must be aligned ±45° from
true north (i.e. north west to north
east). See Collector Orientation
Compass below.
Solar Collector Inclination
• For the most efcient solar gain, the
collectors must be inclined within
10° to 45° from horizontal. See
Collector Inclination Guide right.

• Inspect ttings after collectors are
pressurized with water.
Critical: Fittings must be as
tight as possible.
Warning: Only pressurize the
the collectors for inspection
and de-pressurize them
immediately after inspection.
Critical: Do not leave
collectors pressurised for
longer than 24 hours.
• To prevent damage, collectors
should be left pressurised only when
connected to the storage tank with
appropriate pressure relief valves.
• Collectors can be located a maximum
of 20 metres (with minimal bends)
from the storage tank if pipe layout is
simple.
Note: For more energy
efciency, locate the
collectors as close as
possible to the tank
• This system is suitable for 2 storey
homes.
