2. About your Suntrap Solarius Solar Hot Water System
Congratulations for choosing a Suntrap Solar Hot Water System. All the systems are designed to have the Solar Collectors mounted on the roof, and the Solar tank installed at ground level. Two sizes of Everlast Stainless steel solar hot water tanks are used and have either an electric or gas boost as supplementary heating sources. Tanks have capacities of 250 litres or 315 litres with either a 3.6 KW heater, or a Bosch 26e gas heater.
The Solar Tanks are suitable for installations either inside or outdoors. Tanks installed inside need to sit in a ‘Safe Tray’. If the area in which the system is to be installed is subject to freezing conditions, then the hot and cold solar copper pipes must be fully insulated with closed cell polymer insulation to offer protection against freeze damage.
All electrically boosted Suntrap Solar Hot Water systems are certified to be connected to a dedicated continuous electrical supply.
Risk of scalding
Be aware that the solar hot water temperature can cause scalding. Check the temperature before use. A temperature limiting device
(Tempering Valve) is provided with all Suntrap Solar Hot Water kits and must be fitted to avoid very hot water from the hot taps
(bathrooms, showers etc.)
Temperature adjustment
On electrically boosted systems, the solar tank thermostat maintains the tank temperature during boosting and may be adjusted by a licensed tradesperson if required. The Solar hot water tank thermostat temperature has been factory set and should not require adjustment. The Solar hot water tank is also supplied with a Pressure and Temperature Relief valve (PTR 850 Valve) which must not be tampered with.
The Tempering Valve is required to prevent scalding as solar hot water can be much hotter than just electrically heated water.
The Solar Control Unit will switch the solar pump on to circulate the water when there is a water temperature difference of 8 degrees centigrade or more between the tank water temperature and the solar collector outlet water temperature (on the roof) and will switch the pump off when the water temperature difference is 5 degrees centigrade. In the event of cold weather, the pump will also run to ensure that a minimum water temperature of 4 degrees centigrade is maintained within the solar collectors (to prevent the water within the solar collectors from freezing).
Safety
The tank is supplied with a Pressure and Temperature Relief valve, a Pressure Limiting Valve, and a thermostat. These devices must be kept in working order at all times. High temperatures can exist in the solar pipes and precautions must be taken to avoid young children touching them.
If any power cords or plugs are damaged, then these must be replaced by a licensed electrician.
To turn off the hot water
The water heater boost should remain on unless you plan to be away from home for length of time.
If you need to switch the system off (system close down), switch off the electrical water heater isolating switch (electric element boost heating), switch off the power to the Solar Control Unit (solar heating), Shut off the cold water-in to the DuoValve (point C) and close the Shut-off ball valve (point D) on the Solar control kit.
To turn on the water heater
Open the DuoValve (point C),- this allows cold water to enter the solar tank, switch on the Solar Control Unit and open the Shutoff ball valve (point D) on the Solar Control kit, If the solar collectors have been drained then follow the instructions in section 14 of this document (14. Priming and filling the system).
Heater Boost control
Under ideal conditions, your solar hot water will be kept up to temperature by the solar collectors. However on cloudy and overcast days and during the winter months, the boost heating element inside the solar water tank (electric boost systems) may be activated to maintain your water temperature. The heating element (immersion heater), must have its own dedicated electrical supply and must remain connected to the electrical supply at all times.
Water pressure
The water pressure used with this Solar Hot Water system must be a minimum of 200kpa.
Tank Sizes
250 litre 1.62m(h) x 620mm dia. 315 litre 1.98m(h) x 620mm dia.
Solar collector roof space required
2 collectors 2.4m(w) x 1.8m(h) 3 collectors 3.6m(w) x 1.8m(h)
Installers:
All installations must be carried out by licensed plumbers or other authorised persons in accordance with the National
Plumbing and Drainage Code AS3500, and in addition, with any specific requirements of local water authorities.
Please familiarise yourself with all the diagrams and pictures before starting to connect the system together.
Installation instructions begin at section 10.
Some diagrams/pictures are representative only and some pictures are shown before pipe insulation has been fitted for clarity. To comply with AS2712 certification, the plumbing between the solar hot water tank and the solar collectors must be installed using 12mm internal pipe diameter with insulation thickness of 19mm on the inlet pipe and 12mm internal pipe diameter with insulation thickness of 19mm on the outlet pipe, both pipes using insulation material to
ISOpipe insulation standards. For Gas Boosted systems the pipe between the Solar preheat tank and Gas Booster must use Armaflex 19mm thickness insulation.

Caring for your system
At the top of the Solar hot water tank there is an 850kpa Pressure and Temperature Relief valve, and it is possible from time to time that a small amount of water will escape from this valve when the water inside the tank expands during heating periods. This is quite normal. Every 6 months this valve should be manually operated to ensure that it is in working order. If at any time you believe that your Suntrap Solar Hot Water system is not functioning correctly, then please give us a call.
Regular Care: Pressure and Temperature Relief (PTR) Valve: This valve is next to the top pipe of the solar tank at point J. The valve should be checked at regular intervals and replaced every 5 years. To check that the valve is working properly, gently lift the lever until water flows, then gently let the lever return to its original position. (See Loosing water from the Expansion Control Valve below)
Collector Glass: To assure that maximum efficiency is gained from the Hot water solar system, ensure that the solar collector glass is kept free of dirt. Hose down the collectors with water and use a soft brush from time to time to keep clean.
Water not hot enough:
This may be caused by the following:
Insufficient sunlight – due to cloudy weather, or cool temperatures during winter – check that the booster heater is working in these circumstances.
Booster heating not working – check that it is switched on at the electrical distribution panel.
Solar water not hot enough when conditions are good – Check that the solar pump indicator is illuminated on the Solar Control Unit:
Check that the pump is plugged into the Solar Control Unit: Check that the Solar Control Unit is plugged into the electrical supply, and switched on. Also check that the collectors have unrestricted access to the sun. 2 x solar collectors for a 315 litre tank, with a 3.6
KW boost heater (or a gas booster) is an ideal combination and will provide the solar water temperatures required, under normal working conditions, if the system is working correctly.
Air in system – Proper circulation of water is not being maintained – Ensure that the air vent is open (point K), then remove (purge) any air from the system as described in sections 9 and 14. (9. Connections to the middle and bottom of the Solar Tank and (14.
Priming and filling the system)
Excessive use of water – The different Suntrap Solar Hot water System models are designed to cover the requirements of a small to large number of users, each having their own demand on hot water. A greater demand will cause the water to cool, and longer use of the booster will be required.
Loosing water from the Pressure and Temperature Relief Valve (Point J) – If thermostat in tank is set too high especially in Summer, this can result in excessive use of electrical boost heating, leaving the solar heating little to do. This can lead to extremely high temperatures and water expansion in the solar collectors and can result in excessive water exit from the PTR Valve. Secondary electric boosting ensures that minimal water temperature is maintained and maximises the benefits and efficiency of solar heating obtained from the sun. Suntrap systems are certified to use continuous electrical boosting.
Thermostat setting (Electric Boost) – A high tank temperature setting (active during boost times) should be avoided but may be obtained by the adjustment of the tank thermostat (by a qualified electrician/tradesperson). Please also note that all hot water will be tempered through the Tempering Valve to prevent scalding from the solar hot water.
Holidays – When away for a period of time, close the system down. Switch off and unplug the solar controller and move the Shut off ball-valve at point D to the off position, turn off the ‘mains water in’ at the DuoValve at point C, switch off the booster supply. If freezing conditions are expected while away, leave the solar controller switched on and the Shut off ball-valve (point D) switched on, so the Solar Hot water system will automatically defrost the Solar collectors as required, otherwise drain the solar collectors and close the system down as above.
Installation Notes
In the Sydney area the ideal orientation and angle to mount the solar collectors for the winter sun (best for all round performance) is for the solar collectors to face True North (approx 11 degrees West of Magnetic North) at an angle of 33 degrees. Suntrap U Tube collectors will also work horizontally at an efficiency of 84%, Standard roofs of 26 degrees will provide an efficiency of approx 97%.
The system is designed to operate with the solar collectors installed on a roof at a height greater than the top of the solar hot water tank, with the solar hot water tank installed at ground level. Insulated copper pipes to and from the solar collectors must be direct, and each direction (flow and return) must always run in a continuous rise and fall situation.
The solar collector should be mounted so the Manifold is at the top (higher) level than the bottom of the solar collector.
The tank must be located onto a firm base and sufficient space must be provided around the solar hot water tank for servicing.
Tanks installed inside a property need to sit in suitably drained ‘Safe Tray’.
The Solar Hot Water system uses a different number of solar collectors depending on the system model being installed and the maximum pipe lengths to and from the solar collectors should not exceed 40 meters. Keep the number of 90 degree bends in the pipe work to the minimum. The system must be installed with all copper piping (with insulation thickness of 19mm all the way to the solar collectors and back to the solar hot water tank, and for Gas Boosted systems use insulation thickness of 19mm on the pipe between the Solar Preheat Tank and Gas Booster).
Warning - Roof assembly and installation of the solar collectors should be undertaken in cool conditions (early morning) as the fittings can get too hot to handle and could cause injury if touched.
Warning – When purging the system using the purge valve at point G, extreme caution must be taken as water expelled at this point can be extremely hot. This is best carried out when the solar collectors are cool.
The installation must comply with the requirements of AS/NZS 3000 and AS/NZS 3500.4.
If the tank is to be installed inside a property, then it must be installed in a ‘safe tray’, so that in the event of a leak, the property will not be damaged by water (AS/NZS 3500.4). Draining of the ‘safe tray’ must also comply with AS/NZS 3500.4.

Mains water supply:
The system is fitted with a water pressure limiting valve (connected to the DuoValve at point C). This ensures that the tank is never under excess pressure. The valve is rated at 500 kpa and must never be changed for a higher rating.
Installation of the Solar Hot Water Tank and Solar Collectors:
The Solar Hot water tank and the Solar Collectors are provided as part of the Suntrap Solar Hot water kit, and all components must be installed, maintained and operated as per instructions otherwise all warranties are null and void.

9. Connections to the middle and bottom of the Solar Tank
• The middle Solar tank connection (Point G)
Solar hot water in - has a non-return valve fitted.
• Please note the purge valve which must be used to remove all the air from the solar collectors and the system during the initial fill with water. Failure to bleed air from this point will prevent the solar return water from operating the non return valve. All air must be expelled at this point and only water be present, otherwise the solar water will not circulate between the solar collectors and the tank. WARNING – water expelled from this point can be extremely hot and precautions must be taken.
• The Solar tank temperature receptacle (Point U) is where the sensor cable from the Solar Control unit (front ‘TANK’ socket marked with a blue label) is placed. Push the sensor head in as far as it will go. This is the point where the tank temperature is measured.
• The mains cold water in at the bottom of the
Solar tank connection (H) is made by screwing the complete assembly into the tank.
• The solar recycle connection (solar flow) is connected from Point P on the tank to the inlet to the Solar Pump Shut off Ball Valve (Point D).

10. The completed Solar Hot Water Tank assembly
• The Tank and Solar control kit must be positioned close together
• The Solar tank must sit on firm and level ground
• If the solar tank is to be installed inside a building, then the solar tank must sit within a
‘Safe Tray’ which meets the drainage requirements of AS/NZS 3500.4
Electric Boost:
Solar hot water is piped directly to the domestic hot water taps (via a Tempering valve). An electrical connection must be made from the
Solar Hot Water tank to a dedicated electrical heater supply to provide a ‘boost’ at times when necessary. (switch off dedicated electrical supply and then connect to Point O for this purpose).
Electrical cable entry is via an entry provided to the side of the access cover
Gas Boost:
A separate Gas Boost heater must be installed on the hot water outlet from the solar tank. For maximum operational efficiency the Gas Boost heater (incorporating the Solar Transfer Valve
(STV)) should be mounted as close as possible to the solar tank to minimise the effect of ‘dead leg’ water (water that goes cold in the pipes between the Tank and Gas Boost heater) and to prevent unnecessary activation of the Gas Boost heater.
A Tempering valve is also required to be fitted, prior to the hot water going to the domestic hot water taps.
Set the Gas Boost heater temperature to 70 degrees centigrade.

11. Check List immediately prior to commissioning System
Pre-check list before starting to commission system:
Do not attempt Solar collector installation on a hot day – the Solar collectors and fittings will be too hot to touch
• Turn off mains water supply valve
• Make sure all connections are tightened
• Make sure all fittings are securely tightened
• Ensure Air vent valve has been opened at least 1 turn (and leave open)
• Understand the importance of correctly purging the system – use of the purge valve at point G (and the Test plug in the Solar Controller Unit) – if air is left in the system, this valve will not open and recirculation will not take place: the Solar collectors and pipe work will pressurise, the pump will be put under strain and damage could result.
WARNING – the water expelled from point G can be extremely hot and precautions must be taken.
• Ensure that the temperature sensors are correctly placed and secure – again, if these are not sensing the correct temperatures, the Solar controller will not operate correctly, which could result in the PTR valve on the tank operating prematurely, and wasting water. (incorrect temperature detected and solar tank water gets too warm)
• Turn on mains water supply valve. Turn on the cold water in DuoValve
• Turn on Ball Valve at point D (handle in-line with pipe)
• Check diagram below – connections and components to be installed in the order shown
• OK to start commissioning system

12. Instructions for assembling and fitting the Solar collectors
• Your solar collectors will arrive with the evacuated glass tubes installed. These evacuated glass tubes must be handled very carefully – Please note that these glass tubes never come into contact with the solar hot water, so if they ever got broken during the operational life of the solar hot water system, no solar hot water will ever get lost.
They are easy to replace in-situ and do not require the system to be drained. This is because the Suntrap Solar
Hot water system uses U-Tube solar collector technology which fully contains all the solar water within high pressure copper pipes which run inside the evacuated glass tubes.
As can be seen from the following pictures, the evacuated glass tubes slide into the collector manifold and are retained by plastic shrouds at the opposite end.
16 U-tubes make up each Solar collector
2 x Solar collectors are shown below
3 x Solar collectors are shown below

12. Instructions for assembling and fitting the Solar Collectors (cont)
• The solar collectors are mounted on a Roof Frame which must be installed using the 2 x lengths of galvanised steel (The Frame),
4 x stainless steel straps and screws supplied.
• 4 x ‘L’ shaped brackets attach each collector to the Roof Frame (2 galvanised steel bars)
• The bottom rail of the Roof Frame is then taken to the roof and placed in its lower position. (Hang as A and B below).
The stainless steel straps must be positioned along the frame (two at the top and two at the bottom to line up with the roof rafters under the roof tiles on which to secure the Frame (assuming a tiled roof). On each stainless steel strap, screw one screw into the galvanised steel frame and the other 2 x screws into a roof rafter. Repeat for each stainless steel strap (see over page for details)

12. Instructions for assembling and fitting the Solar Collectors (cont).
The galvanised steel Roof Frame and the stainless steel straps are taken to the roof with no bends in them. When the position of the Roof Frame has been established, slide a tile up and locate a rafter. Using 2 x of the long roof screws, screw the strap into position on the rafter so that there will be a sufficient length exposed beyond the normal position of the tile to attach to the roof frame. Slide the tile back into its normal position. Re-position the Roof Frame, then bend the strap around the Roof Frame to secure. Repeat this for the other 3 x stainless steel straps.
When the stainless steel straps have been bent around the Roof Frame and the Roof Frame is in its final position, drill through both the strap and the frame with a 3 mm drill, and screw together. Repeat this for the other 3 x stainless steel straps.
Slide the spring clamps into position, fit collectors and couple them up, and tighten as detailed previously in this Section 12.

13. Completing the Installation (cont)
• Fit the Solar hot water outlet connector to the Solar Tank, using thread tape, (Point H).
• Connect the DuoValve (P/N DUO00A) and the water Pressure Limiting Valve (P/N PLV00A) together, ensuring that the arrows on the valves are towards tank (point C), using thread tape. Run a length of
15mm pipe from the Pressure Limiting Valve to the tank. Connect a 15mm pipe from the cold water in (point G) to the
Tempering Valve (Point T), Connect the Solar recycle (point P) on the tank to the solar pump inlet Shut off Ball Valve (Point D).
Run a length of 15mm pipe from the DuoValve (Point C) and connect back to the ‘mains cold water in’ connection.
• Connect the Solar Collectors together using the connectors supplied. Use thread tape on the solar collector threaded connections and grease on the Conetite mating surfaces (Points M and or N). Use two spanners to prevent twisting the manifold.
• Run a length of 15mm pipe and connect from the Check Valve (Solar Pump outlet connection – point W) to the Solar Collector inlet connector (Point L). (use two spanners to prevent twisting the manifold when tightening the
20mm-15mm adapter to the collector).
• Run a length of 15mm pipe and connect from the Solar Collector outlet assembly (Point K) to the Solar input on the Solar Hot
• Water tank (Point G).
• Electric Boost – Connect the tank solar hot water fitting (SHW001 – Point F) to the Tempering Valve (Point R).
• Gas Boost - Connect the solar hot water fitting (SHW001 - Point F) to the tank and run a 20mm pipe to the Water Inlet connection on the Gas Booster.
• Gas Boost - Connect from the Hot Water outlet on the Gas Booster with 15mm pipe to the Tempering Valve (Point R)
• Fit the Lower tank temperature sensor receptacle (part of P/N BSR00A) into Point U).
• Fit the Upper tank temperature sensor receptacle (part of P/N BSR00A) into (Point V).
• Connect a cold water feed (from point G) to the Tempering Valve (Point T).
• From the ‘outlet’ connection – (tempered water) of the Tempering Valve (Point S) run a 15mm copper pipe to the Hot water taps.
• Place the 2 tank sensor probes into their respective temperature sensor receptacles (Points U and V on the tank)
• Fit the Solar collector probe into (Point K on the Solar Collector) and run the sensor cable back to the Solar controller and plug in.
• Silicone seal around the sensor cables, only at the entry point to the temperature receptacles.
• (Note that there is an optional facility to utilise an internal relay within the solar controller to limit the boost element times to between 11pm and 6am. The boost element must be wired in series through these normally open contacts to interrupt the Active/Phase wire that powers the element. Please see HWC1 in the Solar Controller Documentation, available as a download from the Suntrap Website).
• Secure any loose cables with cable ties.
• For all Gas Boosted Heater system installations – Please see diagram in Section 4, and notes in Section 10
Gas connection must be carried by a qualified tradesperson – refer to the Gas Boost heater manufacturers instructions.
• Set the Gas Boost temperature to 70 degrees centigrade.
• Check all fittings and tighten as necessary.
14. Priming and filling the system
• Ensure that the DuoValve (Point C) is closed (on the mains water-in pipe)
• Turn on the main water supply.
• Check for water leaks along this mains ‘cold water in’ pipe.
• Turn on the nearest hot water tap fed from the Solar tank (this assists with the removal of air from the system during initial fill.
• Open the DuoValve (Point C) on the Mains water-in pipe to allow water to enter the Solar tank.
• Open the purge valve on the Solar Return Inlet connection to the tank (point G) (very important to prevent an air lock on initial fill). Warning – the water expelled from point G can be very hot and precautions must be taken. This is best carried out when the Solar Collectors are cool.
• While filling the Solar Tank with water - hold open the 850kpa Pressure and Temperature valve
(Point J) – this also assists with the removal of air during initial fill.
• Also while filling the Solar Tank with water - watch for water to be expelled at the purge valve on the Solar
Return Inlet connection to the Tank point (point G) (water will have now partially filled the on-roof solar collectors and pipes) –air will ‘hiss’ until water is expelled). When only water flows, close the purge valve.
• When water is expelled from the P and T Relief valve (Point J), let the valve close.
• Allow water to continue to enter the Solar Tank. Water will begin to come out of the hot water tap previously left open. When there is a steady flow of water, turn off all hot taps. Check for any water leaks.
• Plug the solar pump into the ‘Pump’ socket on the cable which comes from the underside of the Solar Control Unit.
• Plug the Solar Control Unit into a suitable electricity supply, and switch on the Solar Control Unit. The power light should illuminate. Open the purge valve (Point G). Press and hold the PUMP button on the Solar Controller until the PUMP light flashes and the pump should start. Run the pump for 10 minutes to ensure that all the air is excluded from the solar collectors. Close the purge valve. Remove the purge valve key (or the removable handle) to a safe place.
• Press the PUMP button on the Solar controller to turn the pump off.
• Set the Flow Control Valve (Point W) to 1.2 ltr/min.
• Ensure that Silicone seal is around the tank sensor cables but only at the entry point to the temperature receptacle
(for easy sensor removal if necessary).
• When the Solar Collector water temperature sensor (on the roof) detects that the water temperature is 8 degrees centigrade or more above the tank water temperature, the solar pump will run until the water temperature difference is
5 degrees centigrade. The pump will also run to ensure that a minimum water temperature of 4 degrees centigrade is maintained within the solar collectors to prevent freezing. The ‘PUMP’ light will illuminate when the pump is running.
• Check for any leaks and take corrective action.
• On electric boost systems switch on the boost electrical supply.
• Look forward to a very efficient and cost effective hot water delivery system, powered by the sun.
