1. IMPORTANT INFORMATION FOR THE HOUSEHOLDER
ASTIsola models have roof mounted solar panels connected to a ground mounted solar storage tank
and/orboosting heater.The solar input isharvested with a circulation pump controlled byan electronic
temperature differential controller.
1. It is important for the householder to become familiar with the contents of this manual to ensure
safety and to optimise the performance and longevity of this water heater.
2. This water heater is designed for use bya single familydomestic dwelling to provide hot potable
water.
3. Do not operate this water heater until all operating instructions have been read and understood by
the homeowner.
4. These water heaters are NOT recommended for connection to Bore Water Supplies and warranty
may be void in such installations.
5. A properly drained safe tray must be used where property damage could occur from water spillage
(see AS3500.4.2). Ensure this safe tray does not become blocked.
6. If you live in an area that experiences frost in winter months or freezing occurs (below 5°C), please
ask your installer to install ASTIsola Frost Protection Valves (FRPRVA) to assist with preventing
damage to panels. Note that this is a secondary frostprotection mechanism as the solar water
heater is equipped with an electronic freeze control system that will pump water from the storage
tank through the collectors when the temperature of the water in the collectors reduces to 3°C. This
process will cease when the water temperature in the collectors rises to 5°C and may repeat while
the temperature is low. It is imperative that the power supply to the pump and controller is not
interrupted or turned off. Damage to the panels caused byfreeze conditions which occurbelow 5°C
when the power is interrupted or turned off is not covered by warranty. Frost vales only work when
under pressure from the connected water supply, so if your waterpressure is supplied via a
pressure pump (tank water) you must ensure the pressure pump has uninterrupted power supply if
there is a black out during frost conditions.
7. If you live in an area that experience frost in winter monthsor freezing occurs (below 5°C), DO
NOT install anyform of switch to isolate the booster element as your tank is required to be heated
to the minimum of 60°C which forms part of the electronicfrost protection system ensuringhot
water is pumped to the panels. Off peak tariffsare NOT RECOMMENDED. It is highly
recommended to connect the electric element to continuous power in frost areas to ensure water
temperature in the tanks is kept.
8. Do not activate the power supply to this water heater unless the cylinder isfilled with water and a
satisfactory Megger reading is obtained by a qualified tradesperson.

9. Do not block or seal the Pressure & Temperature Relief (PTR) safety valve or drain pipe. Never fit
a PTR or Expansion ControlValve (ECV) with a pressure rating greater than that indicated on the
product-rating label.
10.The water heater warrantycan become void if relief valves orother safety devices are tampered
with or if the installation is not in accordance with these instructions.
11.Do not place any articles, chemicals or flammable materials on or near the water heater
12.Removal of access covers will expose 240V wiring. Do not remove the terminal box cover or gain
access to this water heater unless the power supply has been effectively disconnected by a
qualified tradesperson only.
13.Do not operate this water heater with the terminal box cover removed or loose.
14.This water heater is not intended to be operated or adjusted by young children or infirm persons.
Young children mustbe supervised to ensure they do not interfere with the water heater.
15.This water heater can deliver water at temperatures which can cause scolding. Check the
water temperature before use, such as when entering a shower or filling a bath or basin.
16.Take care not to touch copper pipesconnected to the water heater as high temperatures in the
pipework may be present.
17.The water heater pump / controller must be plugged into a 240V 50Hz10Amp electrical outlet
which may be required to be weatherproof depending on location. Take care not to touch the
power plug with wet hands.
18.If the power supply cord, plug or electrical conduit to the water heater is damaged, it must be
replaced by a qualified tradesperson in order to avoid a hazard.The power supply cord and plug
must be replaced with a genuine replacement part available from Astivita Limited.
19.In times of low solar energy contribution, water stored in the solar tankcan be heated by an electric
booster consisting of an element and an automatic thermostat located on the tank. It is
recommended that the electric boost be connected to a continuous electrical supply; however, if
connected to an Off Peak Tariff, a nightrate tariff is NOT RECOMMENDED. Note that the
thermostat must only be adjusted by a qualified tradesperson.
20.DANGER: FAILURE TO OPERATE THE RELIEF VALVE EASING GEAR AT LEAST ONCE
EVERY SIX MONTHS MAY RESULT IN THE WATER HEATER RUPTURING. IT IS
IMPORTANT THAT THE EASING GEAR ON THE VALVE BE RAISED AND LOWERED VERY
GENTLY. FAILURE TO DO SO MAY RESULT IN THE WATER HEATER CYLINDER FAILING,
OR UNDER CERTAIN CIRCUMSTANCES, RUPTURING VIOLENTLY.
21.IT IS NORMAL FOR SMALL QUANTITIES OF WATER (UP TO AROUND 15 LITRES IN A 24
HOUR PERIOD) TO BE RELEASED BY THE ECV OR PTR VALVE IN THE HEATING CYCLE.
CONTINUOUS LEAKAGE OF WATER FROM THE VALVE MAY INDICATE A PROBLEM. IF
THE VALVE DOES NOT DISCHARGE WATER WHEN THE EASING GEAR IS OPERATED, OR
DOES NOT SEAL AGAIN, A SERVICE CALL SHOULD BE MADE WITHOUT DELAY. THE PTR
VALVE IS NOT SERVICABLE.
22.THE THERMOSTAT IN THE ELECTRIC BOOST IS EQUIPPED WITH AN OVER-
TEMPERATURE CUT-OUT. IF THE OVER TEMPERATURE CUT-OUT ACTIVATES, IT MUST

NOT BE RESET AND THE WATER HEATER MUST BE SERVICED BY AN AUTHORISED
PERSON.
23.The amount of water heated by the electric boost is as follows:
a. SPS270 –121 Litres
b. SPS340 –153 Litres
c. SPS450 –202 litres
24.WARNING: IF THE SOLAR SYSTEM IS NOT USED FOR TWO WEEKS OR MORE, A
QUANTITY OF HYDROGEN GAS, WHICH IS HIGHLY INFLAMMABLE, MAY
ACCUMULATE IN THE SYSTEM. THIS MAY BE OBSERVED AS VIOLENT
'SPLUTTERING' WHEN A HOT TAP IS OPENED INITIALLY. TO DISSIPATE THIS GAS
SAFELY, IT IS RECOMMENDED THAT A HOT TAP BE TURNED ON FOR SEVERAL
MINUTES AT A SINK, BASIN OR BATH BUT NOT AT A DISHWASHER, CLOTHES
WASHER OR OTHER APPLIANCE. DURING THIS PROCEDURE THERE MUST BE NO
SMOKING, OPEN FLAME, OR ANY ELECTRICAL APPLIANCE OPERATING NEARBY. IF
HYDROGEN HAS FORMED AND IS DISCHARGED THROUGH THE TAP IT WILL
PROBABLY MAKE A SOUND SIMILAR TO AIR ESCAPING.
2. HOUSEHOLDER INSTRUCTIONS –Operation and Maintenance
Warning: This appliance not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge.
Children should be supervised by a person responsible for their safety to ensure that they
do not play with the appliance.
SOLAR SYSTEM OPERATION & ELECTRIC BOOST
Ensure that your solar hot water system is filled with water at all times. If drained at any time then the
solar panels should be covered as prolonged exposure to sun without a supply of coolant water may
cause damage.
DO NOT turn off the ELECTRICITY or WATER SUPPLY to the Solar Controller and Pump.
The pump and controller should be connected to a 240V 50 Hz power supply at all times i.e.
throughout the entire year. Even in winter it is important that the controller is able to turn the pump
ON during cold conditions to prevent panel damage due to freezing.
The controller is a differential thermostat which turns the pump on and off in response to temperature
signals received from a hot sensor, located in the solar panels on the roof, and a cold sensor located
in a pocket at the base of the solar storage tank. The sensor cables must not be damaged or cut.

ELECTRIC BOOST
Water stored in the storage tank is heated automatically by an electric boosterelement which is controlled
by an automatic thermostat. The boosterelement heats the water during very cloudy or rainy weather,
during the wintermonths, orduring periods of unusually high demand. Although it is recommended to
connect the electric element to continuous power, it can be connected to an off peak tariff but NIGHT
RATE OFF PEAK IS NOT RECOMMENDED as the available power may not be sufficient during
inclement weatherand you may run short of hot water during these periods.
The electric booster heating element is controlled by an automatic electric thermostat. The thermostat and
element are mounted on the solar storage tank. The boosted water temperature is automatically controlled
to the thermostat setting when the booster heating element switch is in the on position.
The thermostat is tradesperson adjustable. It has a minimum temperature setting of 60ºC and a
recommended maximum temperature setting of 75ºC. It mustonly be adjusted by an authorised person.
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
The electric booster element will automatically heat the water in the upper section of the tank.An isolating
switch can be installedwhich will allow manual control however be aware that if this switch is turned off, a
shortage of hot water can occur during periods of low solar radiation and water temperatures below
600C can give rise to bacterial breeding including Legionella bacteria. Switch not recommended
for frost areas & if installed will void warranty if damage is related to Frost.
Australian Standards therefore stipulate that this switch be left continuouslyon and the automatic
thermostat be set to a minimum temperature of 600C.
PRESSURE & TEMPERATURE RELIEF VALVES AND COLD WATER EXPANSION VALVE
See Solar Layout Drawings to identify these valves.
Never fit a Pressure and Temperature Relief Valve (PTR) or Expansion Control Valve (ECV) with a
pressure rating greater than that indicated on the product-rating label.
It is normal for the ECV fitted to the cold mains water supply to dribble as either the solar panels or
water heater heats water within the system. The expansion valve releases water from the system so
that the system will be maintained at its design pressure.
The PTR valve fitted to the solar storage tank should not dribble during normal operation as they are
fitted as safety valves. If the PTR valve dribbles, operate the easing mechanism on the valve and
allow water to discharge through the drain pipe. Remember this water may be HOT and ensure that
the discharge does not come in contact with anyone. Release the easing lever SLOWLY and reseat
the valve. If the valve is still dribbling 24 hours after reseating contact ASTIsola Service.
If no water is drawn from the system for several days in hot weather conditions the ECV on the solar
storage tank may open and freely discharge water in order to discard the excess solar energy
collected. This should happen only infrequently but it is considered normal operation.
If the PTR valve on the storage water heater freely discharges hot water and steam, turn off the
electricity supply to the storage unit and contact ASTIsola Service.

IMPORTANT: Relief valves should be checked to be in sound working order in intervals not
exceeding 5 years,or more regularly in areas subject to water deposits. Checking should include
operation of the relief valve to remove any lime deposits. The PTR valve should be replaced every
5 years.
FROST PROTECTION VALVES
Frost protection valves (FRPRVA) are available from Astivita Limited and should be fitted to
collectors where solar water heaters are installed in frost prone areas. Where fitted in frost areas, one
frost protection valve is fitted to the bottom of each panel (2 Valves Required) and must be pointing
downwards towards the guttering. It is normal for these valves to dribble during very cold weather.
Failure to install frost protection kits in frost prone areas may void warranty should damage to
collectors occur.
MAINTENANCE
Periodic - as needed (minimum six-monthly) by Owner
Prune or remove trees or shrubs that shade the solar panels. For effective operation the
panels should be in full sunlight between at least 9am and 3pm in both summer and winter.
Panels which are shaded will not function correctly.
Shading from newly erected buildings also needs to be considered and panels relocated if
necessary.
Check cleanliness of solar panel glass. Clean if covered in dust, grime, leaves or other build
up. The panels may be cleaned with water and detergent only when the panels are cool, for
example at the beginning or end of the day or during overcast conditions. If there has been
little rain or if the panel is located in a dusty location it may be necessary to clean the panels
more frequently. Note. Astivita Limited does not cover cracked or broken glass in collectors.
This may be covered by your household insurance policy.
Draining and flushing the water heaters and panels must be undertaken by an authorised
service agent or plumber and not by the householder due to possible high water temperatures.
WARNING!
Working on roofs should always be considered a hazardous activity; by law you
must observe certain minimum safety precautions. These safety precautions are
outlined in the Work Cover Code of practice "Safe work on roofs" Part 1 and 2 and
in the Occupation Health and Safety Act 2011.
Flush and reseat the PTR valve and cold water pressure ECV. This is done by raising the
release lever, allowing water to flow freely and then lowering the lever and allowing the valve
to reseat (this is to remove lime deposits and to verify that the valve is not blocked).
Remember that the water discharging from the valves may be HOT and should not be
permitted to come into contact with anyone.

Annual Service –By authorised Serviceman
Astivita Limited recommends that the Solar System be serviced annually by an ASTIsola accredited
service agent. The components or parts may not be covered by ASTIsola warranty if damage to the
system or parts is caused by the lack of regular maintenance.
It is important that the PTR valves, the cold water ECV and frost valves be replaced every 5
years.
The protective anode fitted to the solar storage tank should be checked and replaced if
necessary at suitable intervals depending on water quality, but no later than every 5 years. It is
recommended that Astivita Limited be contacted regarding a suitable replacement anode.
Changing the anode at regular intervals should extend the working life of the storage tank.
HOUSEHOLDER FAULT FINDING
Prior to contacting ASTIsola for a service call, there are some basic checks that can be made by the
householder. Please note that you will be charged by a ASTIsola service agent where the fault is not
related to manufacture or failure of a part or out of warranty.
NOT ENOUGH OR NO HOT WATER
If the collectors are shade-free, the weather is fine and warm and the solar storage tank contents
are definitely cold, the circulating pump should operate and the return connection become warm
or hot. Please note that the pump is almost silent and vibration-free in operation. Check the
following:
1. Is there 240 volts at the power outlet? Is there a blown circuit breaker, RCD or fuse?
2. Is the pump plugged into the controller? The pump and controller are located under the
plastic terminal box cover on the storage tank.
3. Are the sensors plugged into the correct sockets in the controller?
4. Are the sensors correctly fitted into the sensor pockets on the tank and collectors?
5. Has all air been purged from the system?
6. Has your hot water usage changed?
7. Is the thermostat setting sufficient to recover from hot water usage?
PRESSURE AND TEMPERATURE RELIEF (PTR) VALVE LEAKING
It is usual for a pressure and temperature reliefvalve to release a small quantity of water during the
heating cycle; up to around 15 litres over a 24 hour period is acceptable. If the discharge is noticeably
more than this, contactan ASTIsola service technician.

3. SOLAR TANK INSTALLATION
INSTALLER –PLEASE NOTE THE FOLLOWING
1. THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING
2. All work associated with the installation of this water heatermust be carried out byproperly
trained and accredited tradespersons and be strictlyin accordance with relevant Australian
Standards including AS/NZS 3500.4 and AS/NZS 3000, local, State and Federal Regulations
including, but not limited to, Occupational Health, Safety and Welfare Regulations (OH&S)
3. If this installation is taking place in an area subject to frost conditions orfreezing conditions
(below5°C), the FRPRKI Frost protection Kit containing two frost protection valves should be
installed on the panels.
The solar water heater tank should be installed in close proximity to the most frequentlyused hot
water outlet and its position chosen with safety and service in mind. Other considerationsinclude
the position of the solartank with respect to the solar collectors as heat loss can occur in the pipes,
and copper pipe length should not exceed 20 metres (for 2 panel systems). Also consider
servicing (the water heater must be accessible without the use of a ladder or scaffold and the
anode, PTR valve, thermostat and booster element must be able to be removed) and nameplate
data must be able to be read. Other considerations include:
● Electrical supply requirements for the pump and controller
● Weight of the heater filled with water
● Dimensions of the heater and size and location of connection points
● Water supply pressure limitations
CLEARANCE
Allow adequate room to work with tools. A minimum of 25mm clearance around the water heater is
required. An additional 30mm is required for relief valve removal, 80mm for access cover removal
and 400mm for element removal. You should be able to read the information on the rating plate
and all informative labelling.
Adequate provision must be made to dispose of any water escapingfrom heateror adjacent
plumbing that might result in damage to property.
The water heater must be connected in such a way that:
Space is allowed for the removal of the heating element.
Space is allowed for the removal and replacement of the anode.
The pump is accessible for servicing.

CONFINED SPACES
If the thermostat fails the unit may produce excessive steam.
It is strongly recommended that the heater should be installed in a well-ventilated space to avoid
condensation build up.
If installed in confined areas, make provision for Service Access.
Vent safely to open air and carry hot water overflow pipework to drain.
FOUNDATION
To ensure adequate ventilation, position the unit on an approved support base on a concrete slab
or otherapproved foundation (See figure below). Ensure adequate drainage to prevent water
ponding around the base of the tank when exposed in wet locations.
Alternative formsof water heater bases are acceptable providing they allow for adequate
ventilation and drainage.
Attention is drawn to the weight of the water heater tank when full (up to approximately600kg
depending on model) and the installer should ensure the base andfootings are substantial
enough to avoid subsidence etc.
WATER SUPPLY
If the water heater is installed to a tank water supply, a minimum 200kPa water supply pressure
must be available or a pressure pump must be installed to allow operation of the system
This water heater has been constructed to meet water quality conditions in most Australian water
supply locations. However, harsh water quality does exist in some locations and, if in doubt,
contact your local council or water supplier. Only potable water should be used in this water
heater. If you are unsure of the water chemistry in your area, you may find additional information
by contacting your local water supply authority.
Anode: The anode in your waterheater issacrificial, however it is designed to protect the vitreous
enamel lined cylinder in most public reticulated water supplies forfive years after which time it
should be replaced as part of annual service. However it is important to understand that many
water supplies can exhibit chemical qualities that are not suitable for the standard anode supplied

than 40mg/L, the installed anode may be unsuitable for use to protect your water heater. In these
circumstances, a plumber or authorised service person should be contacted to fit the correct
anode. Different anodes are available in these situations to protect the vitreous enamel lined tank.
Please note that warranty becomes void if the TDS value exceeds 2500 mg/L.
The Saturation Index is a measure of the water’s corrosiveness. Corrosion may result in early
failure of copper parts such as solar collectors and copper sheathed electric components. Water is
considered corrosive should the saturation indexbe below -1.0. Scaling, which is the build-up of
calcium carbonate in the tank, can occur where the Saturation Index is above +0.4. In these
instances where the Saturation Index exceeds+0.4, ensure the expansion control valve (ECV) is
fitted according to instructions contained within this manual. Should thesaturation Index exceed
+0.8, a lowWatts density element must be fitted.
Water heaters installed in locations where incorrectanodes are fitted due to high or low TDS or
where the water is corrosive or considered scaling will not be covered by this warranty.
SOLAR CONTROLLER AND PUMP OPERATION
The Aestiva Solar Controller and Grundfos Pump, supplied with this Solar Water Heater, are
enclosed within a UV Resistant ABS plastic enclosure which is designed to house these
components and protect them from harmful UV radiation. This Pump/Controller assembly is
fitted onto the side of the tank directly above the Cold Water Inlet using 8 off 4mm screws
provided in nut-serts located in the tank.
The control unit turns the pump on and off in response to temperature signals received from a
hot sensor located in the solar panel's hot water outlet fitting on the roof top, and a cold
sensor located at the entry to the storage tank. It is crucial that these sensors and leads are
not damaged or cut during or subsequent to installation.
Note that after 2 hours of operation of the pump, it will automatically switch off for five
minutes before resuming to prevent any possible cavitation of the pump.

The controller incorporates an LCD display that can easily be read to identify the various
sensor temperatures and error modes (shown in bold below).
Temperature Probe Turn On (Pump On Temp) and Turn Off (Pump Off Temp) temperatures
are as follows:
“Pump On Temp”: 8°C Differential (ΔT) between Panel Sensor temperature and Tank
Temperature Sensor (panel sensor hotter than tank sensor).
“Pump Off Temp”: 2°C Differential (ΔT) between Panel Sensor temperature and Tank
Temperature Sensor.
The Controller will also prevent the pump from circulating water to the panels should the tank
temperature, measured at the Tank Temperature Sensor become too high. Temperature
setting to protect the tank is as follows:
“Top Out Temp”: 75°C measured at the tank mounted sensor will de-activate the pump to
protect the vitreous lining of the steel tank.
Freeze protection is also a standard function of the controller. Where the panel temperature
measured at the Panel Temperature Sensor approaches freezing, the pump will activate and
circulate heated tank water to the panels until the panel temperature rises and prevents
against frost damage. Temperature settings are as follows:
“Protect On Temp”: 3°C measured at the roof top sensor will activate the pump.
“Protect Off Temp”: 5°C measured at the roof top sensor will de-activate the pump
Note that when cold conditions prevail overnight, this frost protect mechanism may switch the
pump on and off several times to protect the panels, potentially resulting in reduced hot water
being available in the morning.
The sensor leads are extra low voltage but must to be encased in 20mm PVC conduit and
secured with conduit saddles to ensure they remain undamaged.
The hot sensor (long lead) should be dry and pushed to the bottom of the long hot sensor
pocket on the top left hand corner of the solar panel. A clip on the sensor probe port is
provided to secure the sensor lead.
The cold sensor (short lead) is to be fitted dry into the short cold water sensor pocket at the
cold water entry to the solar storage tank. Refer to the respective layout diagram supplied
with the Solar Storage Tank.

PIPEWORK, VALVES AND FITTINGS
Valves and fittings for connecting the solar panels on the roof and the storage tank are supplied.
The temperature of the water at the outlet connection on the panels may reach 150°C or more
and therefore only copper pipe can be used between the panels, storage tank and boosting
heater.
Class B copper pipe should be used and the runs should be as short as possible to reduce
heat losses.
The pipes MUST be lagged using thick-walled foam of at least 19mm thickness, RO.6 and
should be weather proofed and UV stabilized.
If insulation is not UV stabilized, it must be protected by a suitable UV resistant paint.
Pre-cut pieces of insulation and cable ties are provided to insulate the pipework fittings. The
areas to be insulated are: inlet pipework fittings to the panel, the outlet pipework fittings, and
on 2 & 3 panel systems the joiners between the panels. These fittings must be insulated to
protect them from freezing in cold areas. Warranty may be void if not fitted. Refer to the Solar
Panel Layout drawings for location and installation detail. Water may drip from the pipe of the
pressure-relief device. This pipe must be left open to the atmosphere
