1. Water supply is connected to the system.
2. The water then fills up the riser pipes and storage tank.
3. When solar radiation is absorbed, water becomes hot and rises.
This is called the Thermosyphon principle.
4. The hot water then rises and stores in the insulated hot water
storage tank.
5. Hot water supply outlet.

• Storage Tank
The storage cylinder is made of 1.5mm stainless steel is to withstand
higher operating pressures and water temperatures.
• Insulation
The hot water storage insulation is pressure injected CFC Free
polyurethane foam which is a combination of polyol, isocynate and
a blowing agent. This insulation keeps hot water temperatures hotter
for longer periods of time.
• Casing
Made of aluminium stucco, it is corrosion and rust proof to withstand
all sorts of weather conditions and rainfall. A wash after a few years
will give it a brand new look.
• Hot Water Enhancer
This feature reduces the inertia of water going into the system so that
hot water temperatures are not drastically reduced.
• Electric Element & Thermostat
This electric element combined with a thermostat is provided in the
event of continuous rainy days or when more hot water is required. If
switched-on, water temperature will reach the pre-set temperature
of 60 Degrees Celsius before cut-off.
• Pressure & Temperature Relief Valve
This safety valve is provided to protect the storage tank from extreme
water pressures and water temperature. It will release in the form of
steam or water.

• Tempered Glass
The solar glass cover is made of 4.0mm tempered glass for durability
and higher transmittance of solar radiation.
• Absorber Plate
The absorber plate is made of 0.3mm aluminium and coated matt
black polyester to absorb more heat from the solar radiation. It
comes in a complete piece for maximum heat transfer and minimal
heat loss.
• Copper Risers
There are six copper risers per solar collector and these copper risers
are bonded to the absorber plate for maximum heat transfer.
• Collector Insulation
The collector insulation ensures that heat trapped by the solar
collector through solar radiation is maximized and not lost through
inferior collector insulation.
• Header Pipe
There are two header pipes per collector, one for the cold water
entry and the other for hot water exit from the solar collector. These
header pipes link all copper risers together and are inter-connected
during installation by brass fittings.
• Collector Casing
The collector casing is made of marine grade aluminium for longer
lifespan and to ensure that the heat absorbed during solar radiation
is kept to a maximum.

• First connect the two collector sockets at the solar collector as
shown in the diagram but do not tighten as yet.
• Then push the other solar collector to connect with the collector
unions and tighten all collector union plugs.

• Now that you have successfully assembled the system, all you need
to do is connect the water supply, cold water inlet and hot water
outlet.
• First ensure that all connector and end plugs are tightened.
Secondly, please ensure that electric element is also tightened.
Never switch-on the electricity before the system is completely filled
with water.
• Now connect cold water supply inlet to the end-fill nut on the long-
arm. Just before cold water connection to the end fill nut, a non-
return valve must be installed to prevent back-flow. Hot water outlet
connection is at the 'T' Connection (see previous page).

• If it is a pitch roof, the solar hot water system should sit on at least two
rafters and at least 7-8 batons.
• Pitch inclination should not be more than 45 degrees
• Remove tiles to expose rafters and batons where location has been
identified.
Nail Stainless Steel Straps on rafters Replace roof tiles back to original position

• The first thing to do is to strap the solar collector.
• Then strap the storage tank.

• For flat roof installations, a bracket is required. Normally the bracket is
made of aluminium as it will not rust or corrode. If a galvanized iron
bracket is made, then it should be coated with red-oxide or any anti-
rust solution.
Bracket dimensions should fit the solar hot water system. Please
check complete system dimension before fabricating bracket.

22.
• For concealed tank installations, the ideal conditions would be, 1.
The pitch of the roof should be steep but not more than 45 degrees,
2. The distance between the solar collector and the storage tank
should not be too far apart and 3. The storage tank must be higher
than the solar collectors.
• For concealed tank installation, a service tray should be made to fit
the entire storage tank in the event of servicing.
• The inter-connecting pipes from the solar collector to the storage
tank should be insulated.
• The drain pipe for the pressure and temperature relief valve must be
fitted and the drainage to a reliable drain source.

• Storage Tank Must Always Be Higher Than Solar Collectors

• Two units in Series Connection
• For series connection, the maximum number of units per series is
6. If the total number of units is 8 or more, then you need to
divide them into two groups of 4 each (see next page).
• It is strongly recommended, if the total numbers of units exceed
6 units, try to accommodate for even number of units for
maximum efficiency and reduction of sleeping units.

• Eight units in Series Parallel Connection
• First in last out rule must be observed at all times

• Can my roof take the weight of the solar hot water system?
Yes. The weight of the solar hot water system is spread over an area
approximately 8 ft. by 8 ft. and sits on about 64 standard roof tiles.
Nevertheless, if required it is recommended that an inspection of the roof
and roof thrust is done.
• Where the solar hot water system should be installed?
Ideally the solar hot water system should be installed facing north or south.
However, if this is not possible then the ideal option would be to face east.
• What happens if it rains?
If the rain continues for days and there is insufficient solar radiation, the
back-up booster can be switched-on. REMEMBER to switched-off after use
as the electric booster will work again if the temperature drops below 60
degrees.
• What if there is no cold water supply from the mains?
There will be no hot water coming from the solar hot water system if there
is no cold water supply as the solar hot water system is a pressurized
system and therefore requires water pressure to push the hot water out.
• How many systems do I need?
This depends on the number of people you have at home and also the
type of hot water facilities you have in your bathrooms. For a basic family
of about 6 - 8 people and an average sized home, a 300 litres system
would be sufficient for 2 showers per day.

28.
• When is the best time to install the solar hot water system?
The best time to install the solar hot water system is when the plumbers
have laid the hot water pipes and before the plastering begins. This will
allow your plumbers to test the pipes with cold and hot water and if there
are no leaks, the plastering can begin.
• How long does the solar hot water system takes to heat up?
In tropical climates the solar hot water system takes about 2 and a half
hours if the correct inclination and orientation has been adhered to. This
also depends on others weather condition such as wind, insolation from
clouds, trees etc.
• What if the cold water pressure in my house is not good?
If this low water pressure problem exists, then it is better to consider an
automatic water pressure pump as it will help you to increase the water
pressure in your home.
• What sort of maintenance is required?
Basically there is no maintenance required as the only moving part is
water. However, if you live near an area where there is quite a lot of
pollution, like near an industrial estate, then a good wash every 12 months
would be good. The pressure and temperature relief valve, although it
lasts more than 10 years is recommended to be change every 7 years.
