7 . FILLING THE COLLECTOR 1 . Fill in collector with water from the long plastic pipe 4.4 until a small quantity of water overflows from the short flexible pipe 4.5 , sign that collector is full and ventilated . 2 . Then you connect : Filling is done using water and antifreeze. The recommended antifreeze is propylene glycol that is non‐toxic. Quantity of propylene glycol shall depend upon frost conditions. 13 ... -
Page 14: Ventilation
Filling of the collector(s) with water and antifreeze shall be done in the morning or in the afternoon during summer months, in order to avoid forming of air bubbles due to overheating, thus causing air trapping, because then the system would not be properly ventilated and it is possible to retain which would reduce performance. Filling up of the collector(s) is to be done with low flow, to let liquid to come out from the opposite copper pipe for better ventilation. The filling with antifreeze is to be done according to the instructions of the ▫ antifreeze (see table) i.e. according to the exterior temperature C under which the system is functioning. 8.VENTILATION Special attention is needed to provide adequate ventilation for the collector(s) so the system runs without problems. Let the hot water ‐ liquid to flow from the opposite site of the filling. Do not fill the system when the collector has been exposed to sun for more than 15 min in summer months and more than 30 min in other cases, because overheating would cause the formation of bubbles in the collector’s loop resulting in malfunctioning. 9 . STORAGE TANK ELECTRICAL CONNECTION For hot water during cloudy days , there is the storage tank electric resistance as a backup . 1 ) Storage tank has to be already full of water . 2 ) Adjust the security thermostat to 50 – 60 ° C. 14 ... -
Page 15: Lightning Protection
10. LIGHTNING PROTECTION In case the collector, is placed on the highest part of the building as usual, special measures for lightning protection shall be taken according to the pertinent regulations. One lighting rod should be considered to install .If there is ready – made lightning protection device, please connect it with collector . 11. ANTIFREEZE PROTECTION Depending on the place of the collector(s) installation there are potential freezing conditions that can cause damage to the collector and the piping. Thus the use of propylene glycol as antifreeze for the protection of the collector(s) and piping is obligatory . The following table gives the necessary volume ratio of antifreeze (water‐antifreeze mixture) for protection against low ambient temperatures, while table no 2 gives the capacity of collector S 2.0 in water. 15 ... - Page 16 ATTENTION: for the right ratio, you have to increase the ratio of the capacity of the collector S2.0, in antifreeze, with the additional quantity A) of the piping form the collector to the boiler B) with the capacity of the closed system of the storage tank .

Page 17: Maintenance Requirements
12. MAINTENANCE REQUIREMENTS 12.1 General The collector(s), as all other devices, needs basic maintenance to ensure constant and high performance at all times. There are various actions that can be done by the user; other actions must be carried out by the manufacturer’s licensed service crew. For high performance and long service life of the entire water heating ‐ distribution installation , maintenance is required and for the rest of installation (boiler, piping, control systems). 12.2 Regular maintenance by the user It is preferred that the user checks twice per year the place where the collector(s) is placed and visually controls the collector and the rest of the components. More specifically: ‐check the leaks in collector’s piping and the leaks in components ‐check for any condensation of the collector ‐check the installation of the collector on the mounting kit and the screws on the mounting kit in order to find any loose screws because of the wind etc. ‐if for any reason there is a need to fill the closed system of the collector with water, you should also add antifreeze to retain the ratio according to table No. 1 ‐Observe any probable cracking of the collector’s glass ‐ Observe the clarity of the glass ‐Observe the condition of the piping insulation conveying water from the collector to the boiler Cleaning of the collector’s glass, when required, is best done without too much sun. It is recommended that a skilled authorized technician visits the installation in all other cases. In case of glass cracking, the glass should be replaced immediately because there is risk of collector corrosion. 12.3 Maintenance by service crew every three years It is recommended that the following controls shall take place periodically every three years by a licensed team: ‐check glass (cleaning, cracking, shading of collector) ‐check collector’s support on the mounting kit ‐check water‐tightness of collectors ‐check insulation of collector It is recommended that the licensed team fill in a printed form quoting the following: ... -
