2 Hydronic module The hydronic module reduces the installation time. The unit is factory-equipped with the main hydronic components required for the installation: variable speed circulator, expansion tank and safety valve. The hydronic module is integrated into the unit without increasing its dimensions and saves the space normally used for the water pump. COOLING The water heat exchanger and the hydronic module are protected against frost down to -10°C, using pump cycling. 1 2 Hydronic components 8 kW 7 1 6 5 8 kW 1 2 4 12-15 kW 7 12-15 kW 4 1 2 3 4 2 1 4 4 3 4 4 5 6 3 3 4 4 Legend 30RB___9 Integrated water circuit (with pump) 1 Automatic purge valve 2 Flow switch 3 Safety valve (1/2” outlet) 4 Temperature sensor 5 Circulation pump 6 Plug to unblock seized pump 7 Expansion tank 46 30RB___X9 Integrated water circuit (without pump) 1 Automatic valve with air vent 2 Flow switch 3 Safety valve (1/2” outlet) 4 Temperature sensor C A R R I E R 2 0 1 6 / 2 0 1 7
