Sequence of Operation - Solar The following sequence of operation is common to 590, 591 & 596 models and pertains to the solar circuit which is a ‘closed circuit’ containing a heating fluid consisting of propylene glycol and water. For information on electric and gas booster operation refer to page 10. Refer to ‘Sequence of Operation Component Diagram’ on page 10 to view components shown in brackets e.g. (1). 1. When power is supplied to the appliance the controller (1) performs a self check routine.
9. Once the pump (6) ceases operation the system commences to drain back. Fluid in the collectors (8) begins to fall back to the bottom of the heat exchanger (9) via the cold pipe (10) due to gravity; this creates suction on the fluid in the hot pipe (12) which is also drawn back through the collectors (8). At the same time the heated vapour in the heat exchanger (9) is rising up through the distributor (11) and into the hot pipe (12) also forcing the fluid back through the collectors (8).
Gas Boosted Integrated Plumbing Arrangement Solar Circuit It is imperative that both the collector hot and cold pipes must fall continuously by at least 5º, or a 1 in 10 fall, to ensure proper drain back of heat exchange fluid into the storage cylinder. Each collector should be angled 10-15mm from horizontal towards the hot outlet to ensure proper drain back of heat exchange fluid and to ensure that the hot sensor is located in fluid when the pump is on.
Solar Circuit Plumbing Diagrams - All Models The solar collectors must be the highest point of the system. The maximum height of the solar installation, from the base of the solar storage tank to the top of the solar collectors, is 9 m. The pump supplied will not circulate closed circuit fluid through heights greater than 9 m and solar gain will not be achieved. For heights greater than 9m, an auxiliary pump kit (PN 299914) must be installed.
Auxiliary Pump - Solar Circuit The maximum height of the solar installation from the base of the solar storage tank to the top of the solar collectors is 9 m. The pump supplied with the solar storage tank will not circulate closed circuit fluid through heights greater than 9 m and solar gain will not be achieved. For heights greater than 9 m, an auxiliary pump kit (kit PN 299914) must be installed above and within 1 m of the solar storage tank.
Potable Water Plumbing Diagrams Plumbing Diagram - 590 & 591 Models Two temperature zones utilising temperature limiting device Plumbing Diagram - 596 Models Two temperature zones utilising temperature limiting device integrated with water heater Gas boosted integrated plumbing behind front access cover contains a tempering valve and provides both a hot (75ºC) and tempered (50ºC) water outlet. Note: Refer to page 11 for gas boosted integrated plumbing arrangement.
Electronic Controller The control board or electronic controller is used to control the pump by monitoring the water temperatures and heat transfer temperatures at various locations within the system. By monitoring the temperature of the heat transfer fluid returning to the solar collectors (cold sensor) and the temperature of the fluid at the outlet of the collectors (hot sensor), the controller adjusts the pump speed to regulate the temperature rise through the collectors to 10ºC.
Solar Monitor Plug Polarity Test 1. Release water from the T&PR valve until the water temp in the cylinder is < 75ºC. 2. Switch off power for 5 seconds and then restore power. 3. If the LED flashes green (any combination) or is solid red within the first 15 seconds from restoring power, the solar monitor plug is inserted the wrong way around. Solar Monitor LED Indication Each flash lasts for 0.5 seconds and each series of flashes is separated by a two second interval.
Pump An electro-mechanical device that pumps solar transfer fluid through the collectors by centrifugal force. The control board varies the flow rate of the pump by pulsing the electrical supply to the pump motor. The flow rate is proportionate to the pulse rate. e.g. higher pulse rate = higher flow rate. Pump Relay The pump is controlled and switched by the control board however the pump power supply may be interrupted by the relay in the event of a software malfunction or over temperature condition.
Heating Unit (Element) - 591 Models Only A tubular device containing an electric resistance element that converts electrical energy to heat. Standard element ratings are 2.4kW, 3.6kW and 4.8kW. Integral Gas Booster - 596 Models Only An Integrity 26 litre electronic gas instantaneous water heater mounted externally on the heater jacket which will boost the solar preheated water to 60ºC if required. Refer to page 10 for more information.
Effective 10/08/07 – Solar Cold Connection • • • The cold pipe which is foamed into the heater had the large brass fitting removed so that just the pipe protrudes. Item 2 – Union ½”C x ½”M is replaced by 088065 compression union ½”C x ½”C which is now item 2a. Item 10 - 087035 Rubber disc is replaced by 221754 Kelvindale plug which is now item 10a. Note: This means the solar cold connection is different although the installing plumber still makes to two ½” copper connections.
Common Faults When a complaint is lodged about the performance of a hot water system there are a number of causes that should be checked and eliminated. In an attempt to pinpoint the most likely cause it is important to discuss with the customer their reasons for the complaint, the duration of the problem, any change in circumstances or usage and recent weather conditions. This information in conjunction with the following listed common complaints will assist you in locating the most likely cause.
Roof leaking This complaint is usually made during or after wet weather and normally soon after commissioning a new water heater. The movement of persons on the roof during installation can crack roofing material if the load is borne on specific points or the roof material is brittle. \ Replacement of damaged roof materials is essential. Use of a woven plastic roof sheet below the collectors will make water penetration more difficult in the future.
Testing the Sensor Strip Unplug the sensor strip plug from the control board and using a multimeter on the kiloohms scale, measure between the pins of the sensor strip plug*. There are six individual tests to be performed as there are six individual sensors contained along the length of the sensor strip (sensors S0 – S5).
Testing the Hot and Cold Sensors Unplug the relevant sensor from the control board and remove the sensor from its location so its temperature will be the same as the ambient air temperature. Using a multimeter on the kilo-ohms scale, measure between the two pins of the sensor plug*.

Commissioning Procedure Solar Circuit It is necessary to commission and check the operation of the solar circuit upon initial installation and whenever closed circuit fluid is lost due to leakage or when performing a closed circuit component replacement procedure i.e collector replacement. The commissioning procedure includes: • Checking the circulation of closed circuit fluid through the solar circuit. • Checking the drain back function of the solar circuit.
The closed circuit fluid contains food grade additives (rust inhibitor, anti-freeze agent, colour) and is harmless to the environment. However, it is good practice to recover any excess closed circuit fluid and remove from site for appropriate disposal. Warning: Although non-toxic, the following first aid advice and procedures should be followed if the closed circuit fluid concentrate comes into human contact or is spilt: • Swallowed - give milk or water and seek medical attention.
2. The solar collectors will gain a high level of heat during periods of solar radiation. If the solar pump is activated during a period of high solar radiation and the solar collectors have not been covered, the initial flow of closed circuit fluid will absorb this heat and a rumbling sound may be heard. This is normal and the solar circuit will achieve a stable operating condition once full flow through the solar circuit is established. 3. The solar pump is set on speed setting 3.
6. Disconnect the drain line from the solar circuit relief valve at the top of the solar storage tank. Remove the spring clip from the solar circuit relief valve and remove the valve. Warning: The solar circuit may be under pressure. Take care when removing the solar circuit relief valve, as a sudden discharge of pressurised hot vapour may be experienced. This discharge will create a sharp sound of vapour being released. 7. Open the heat exchanger drain valve and remove the plug from the end of the hose.
• The hot sensor lead is disconnected at the solar storage tank. If connected, disconnect the hot sensor lead at the solar storage tank (refer to step 9). • The isolation valve in the pipe work between the outlet of the heat exchanger and the solar pump, located behind the pump access cover of the solar storage tank, is fully open.
15. Note the level of the closed circuit fluid in the fluid level hose. The closed circuit fluid should drain back to the original static level. If the closed circuit fluid does not drain back completely to this level, then check: • There is a continuous fall of at least 5° (1 in 10 grade) in the solar pipe work from the solar collectors to the solar storage tank. • The solar collectors have an inclination of not less than 10°.
17. Determine the correct amount of water to be added to or closed circuit fluid to be drained from the heat exchanger if the dynamic level is either below the text marking “MINIMUM FLUID LEVEL WITH PUMP OPERATING” or more than 150 mm above this mark. Each 100 mm of fluid level height is equivalent to three (3) litres of closed circuit fluid. 20 mm 40 mm 60 mm • 0.6 litres 1.2 litres 1.8 litres 80 mm 100 mm 120 mm 2.4 litres 3.0 litres 3.6 litres 140 mm 160 mm 180 mm 4.2 litres 4.8 litres 5.
18. Add water to top up the level of the closed circuit fluid in the heat exchanger if required. To add water to the closed circuit fluid: • If not already removed, disconnect the drain line and remove the spring clip from the solar circuit relief valve at the top of the solar storage tank and remove the valve (refer to step 6). Warning: The solar circuit may be under pressure. Take care when removing the solar circuit relief valve, as a sudden discharge of pressurised hot vapour may be experienced.
Pressure Testing the Solar Circuit 21. Close the heat exchanger drain valve. 22. Refit the solar circuit relief valve, orientating the valve outlet to the rear of the solar storage tank. Secure with the spring clip. Reconnect the drain pipe to the valve. 23. Switch on the electrical supply at the isolating switch to the solar storage tank. Warning: Take care not to enter the area inside the solar storage tank behind the access covers whilst the power is on as the electrical circuit will be live.
Remove Closed Circuit Fluid Level Hose 29. Remove the clear hose from the solar storage tank when satisfied the commissioning procedure is complete. To remove the hose: • Ensure the heat exchanger drain valve is closed. • Remove the hose from the side of the storage tank and place the end into a container to collect the closed circuit fluid remaining in the hose. • Replace the plug into the free end of the hose and lay the hose flat on the ground.
