IE2 otors as standard fro,75 kw to 5,5 kw - IE3 7,5 kw. ALICATIONS The AUATWIN TO sets have been designed and produced to eet the needs of the odern engineering solutions of rain water recycling systes, with consequent saving of drinking water. They are suited to ediu to large applications, such as schools, healthcare establishents, hospitals, apartent coplexes, hotels, gys, shopping centres, for all uses where drinking water is not required for toilet flushing, floor washing, irrigation, car washing, etc. AUATWIN TO characteristic features are versatility of use, silent operation, reliable operation, copact and stable structure. CONSTRUCTION FEATURES AUATWIN TO has a sturdy etal sheet structure, with black cataphoresis paint coating. In addition to better protection fro corrosion and aggressive agents, this solution offers an aesthetically pleasing and captivating look. The structure very efficiently contains the pup set in the botto section, the control panel on the side, and at the top a 15 litre water reservoir, which guarantees continuity of the supply also in case of lack of rain water. The adjustable base feet ensure stability also on irregular surfaces. ADVANTAGES IN TE USE OF UATWIN TO AND RAIN WATER RECOVERY The rain water recovery syste has the objective to reuse rain water as an alternative to water fro the public water network. The rain water, stored in appropriate tanks, can be used to supply all those services that do not need drinking water (washing achine, WC, etc.). Water savings are therefore guaranteed. It is calculated that in doestic application the daily water requireent per person is 15 litres. This is particularly due to the use of the WC flushing syste, cleaning activities, washing achine, garden irrigation, car washing, etc. Approxiately 5% of this water consuption can be et with rain water. The use of rain water offers econoic savings, in line with water savings, and therefore of 5%. In addition to water and econoic savings, the reuse of rain water offers other advantages due to its cheical coposition. Rain water has a liited lie content. This results in softer water, with advantages for the syste: - liited presence of lie scale in the piping syste. - liited aount of lie residuals. - detergent savings, and therefore less pollution for the environent.

2 YDRAULIC SECTION The hydraulic structure of AUATWIN TO is split in several sections. AUATWIN TO RAIN WATER RECOVERY SYSTEM RESSURE BOOSTER SETS B C F The puping section, siilar to a standard doestic pressure booster set consisting of: A B C CONNECTION TO TE RAIN WATER TANK - TROUG TREE-WAY SOLENOID VALVES CONNECTION TO TE 15 L TANK - UBLIC WATER MAINS STAINLESS STEEL DELIVERY MANIFOLD, WIT OSSIBILITY OF CONNECTION ON BOT SIDES E D D 8 LITRE EXANSION VESSEL AND RESSURE SENSOR F MANOMETER G JETINOX OR EUROINOX UMS A G And of a section for autoatic refilling of the 15 litre water reservoir with drinking water, using a so-called AIR GA syste, which coplies with UNI EN 1717: rotection against pollution of potable water in water installations and general requireents of devices to prevent pollution by backflow. AUATWIN coplies with this standard thanks to the "AIR GA" syste, which consists in an air gap that prevents contact between water fro the public water network and rain water, eeting the safety distance requireents between the point of supply and the axiu tank level (overflow liit "").

3 AUATWIN TO RAIN WATER RECOVERY SYSTEM RESSURE BOOSTER SETS ELECTRICAL SECTION I 55 protection class self-extinguishing, shock-resistant plastic electric control panel on the on the front section. The control panel protects the electric pups with an aperoetric protection against dry run and controls the operating sequence, keeping the syste at an average pressure value already preset at the factory. The average pressure value ay be changed using a trier found inside the control panel (S). The pup starting order is switched at each operating cycle. A dedicated electronic card anages the rain water tank levels (AUATWIN TO can handle one or two independent first collection tanks), controlling the two rain water/ public water network switching solenoid valves and the refilling of the 15 litre tank to ensure service continuity. Front panel coponents: - General disconnector with padlockable door lock. - AUT - - MAN function selection pushbuttons. - Alar RESET pushbutton. - Operation, stop, alar notification laps. - Overflow alar buzzer. - Syste onitoring graphic display. Soe additional connections are possibles in the E-Nox card, including: - Dry run or overpressure pressure switch connection terinals (optional). - Alar notification clean contacts (voltage free).
