Page 2: Care For Your Equipment And Safety
Vision Solar Systems - 100 L Gravity Fed Type IMPORTANT NOTICE Please read this manual immediately on receipt of the equipment, before unpacking and installation. Failure to comply with these instructions can render warranties null and void. Care for your equipment and safety Read these instructions before preparing to install the solar water heating system.
Page 3 Vision Solar Systems - 100 L Gravity Fed Type The Electrical Element should be connected by a qualified electrician registered with the Electrical Contractors Board. This will insure that a correct and safe installation is completed. Ensure that all electrical connections are kept dry and protected from the ingress of water and moisture.

Page 6: Unpacking
Vision Solar Systems - 100 L Gravity Fed Type Unpacking It is important when receiving the equipment that you confirm that all the components of the system are received and are in good order. Listed below is a table of some of the most common parts ordered with an indication of whether these parts are supplied as standard or as optional equipment.
Page 7: Principal Of Operation
Vision Solar Systems - 100 L Gravity Fed Type Principal of Operation Construction The system comprises an inner storage tank, an outer cladding and an insulation medium between the two. A cistern tank with a ball or float valve is attached to the main tank and acts as a control valve to keep the main tank full.
Page 8 Vision Solar Systems - 100 L Gravity Fed Type The Collector The collector consists of vacuum tubes that contain some of the thermal fluid (water) and are connected into the tank via a silicon grommet type seal. The vacuum tubes are constructed from two extremely strong Borosilicate glass tubes of different diameters and placed one inside the other.
Page 9 Vision Solar Systems - 100 L Gravity Fed Type Maintaining the energy in the thermal storage tank The tank is constructed of double shell much like the tubes. The inner shell is stainless steel and contains all the connections and seals for the pipes and tubes. This tank is open to the atmosphere and is not under any pressure.
Page 10 Vision Solar Systems - 100 L Gravity Fed Type 2) The tubes are cool on the outside; consequently there is no danger of being burnt should they be touched. 3) No pressure and temperature relief valve is needed provided that the system is correctly installed, with the vent pipes not extended more than 1 meter above the main tank.
Page 11: Performance
Vision Solar Systems - 100 L Gravity Fed Type Performance The output of the solar water will depend on the amount of solar irradiation that reaches the collector throughout the day. On a good day, with 6-7 hours of sunlight, the glass tubes will collect enough energy to heat the water up to 60ºC - 70ºC.

Page 14: Installation
Vision Solar Systems - 100 L Gravity Fed Type Installation Tools Required It is essential that the installation is completed by an accredited plumber who has been trained in solar water installations and has completed an installation training course on this type of solar system.
Page 15 Vision Solar Systems - 100 L Gravity Fed Type Frame Assembly Assemble the frame as indicated in the sketch below: Ensure that all the bolts and nuts are tight. Securing the System Ensure that the intended location is sufficient to support the full weight the system when it is filled with water, and that there will be negligible sag that can damage rigid materials such as tiles if there is any movement.
Page 16 Vision Solar Systems - 100 L Gravity Fed Type Rotate the tank so that the bolts are approximately in the middle of the slots. Place the reservoir tank mounting bracket over the pipe inlet on the right hand side of the tank near the pipe connections.
Page 17 Vision Solar Systems - 100 L Gravity Fed Type Inserting the Vacuum Tubes Do not fill any tubes with cold water if they have been exposed  to the sun. The sudden contraction will cause them to fracture. Keep the tubes covered and in the packaging when not preparing them for insertion into the tank.
Page 18: Using A Timer On The Electrical Heating
Vision Solar Systems - 100 L Gravity Fed Type Using a timer on the Electrical Heating (Optional) Fitting a Timer Enervision recommends that a timer is fitted to control the supply to the element. This should exclude the peak demand periods in the morning between 7am and 10am, in the evening between 6pm and 9pm, and also between 10am and 3pm when normal solar water heating is taking place.

Page 20 Vision Solar Systems - 100 L Gravity Fed Type First Filling with Water and Commissioning Do not fill any tubes with cold water if they have been  exposed to the sun. The sudden contraction will cause them to fracture.
Page 21: Cleaning
Vision Solar Systems - 100 L Gravity Fed Type  Monitor the current on the electrical element with a tong tester. (Do not confirm with voltage measurements.)  The system is now ready for use and will require some time to heat. See performance information on page 11 to gauge the time it will take to heat the water sufficiently.
Page 22 Vision Solar Systems - 100 L Gravity Fed Type Inspection for leaks  Inspect the cold water pipework from point of supply to the geyser for leaks. Look for wet marks below the pipe or markings on the pipe for indication of leaks.
Page 23: Trouble Shooting
Vision Solar Systems - 100 L Gravity Fed Type  Measure the current into the element (1.5kW ± 6.5A) Switch off bypass.  Purging the tank If the water quality is poor, it is recommended that the water in the tank is purged every 6 months to a year to reduce the concentration of salts.
